The USTUTT group started a decade ago to work on solid state quantum spintronics and quantum optics as well as metrology and biophotonics. The group comprises 5 senior scientists, 10 PostDocs and 20 PhD students. Major research areas are diamond-based quantum technology including magnetic and electric field sensing as well as design and application of photonic and plasmonic nano- and microstructures. Rare earth quantum structures are used for quantum spintronics as well as biophotonics. Among others the work is supported by an ERC Advanced Grant which started in 2017.
The Stuttgart group has pioneered the field of solidstate spin physics most notably diamond spintronics and sensing geared towards quantum applications in diamond as well as novel sensing application of diamond defects is such diverse areas as medical diagnostics or fundamental tests of quantum physics. Starting from the first successful observation of single defects, the group demonstrate quantum operations in single defects and bring together materials scientists as well as quantum physicist to work on engineering quantum grade diamond material and structures. The group pioneered the field of nanodiamond application is sensing and bio labeling applications. The achievements represent milestones in demonstrating stable defect fluorescence for small doped nanodiamonds and combining optical microscopy with techniques known from magnetic resonance imaging to demonstrate ultraprecise location of defect centres.
In the past years, the group has gathered considerable expertise in quantum nano sensing using spin defects. Also, the applicants group has gathered considerable knowledge in defect engineering and materials surface preparation. The applicant also has expertise in biophysics and single molecule spectroscopy, required for the present project.
Role in project
In WP3, USTUTT takes advantage of our micro- and nanofabrication facilities. They fabricate solid immersion lenses directly on diamond using photolithography, chemical reflow of the photoresist and reactive ion etching. This will increase the number of collected photons from single NV centres and small, localised ensembles. Since the fabrication process is scalable, it is of particular interest for commercial applications.
In WP5, USTUTT develops a new sensing functionality for robust and accurate electric field sensing with solid state spin ensembles. USTUTT tailors the spin Hamiltonian via proper magnetic field adjustment to map out the ac electric field strength and polarization. For high precision measurements, classical lock-in detection with aspects from quantum phase estimation are combined for effective suppression of technical noise.
USTUTT further demonstrates quantum-enabled thermal sensing by use of NV centres. Backing on promising proofs of- concepts that have sparked increasing interest worldwide, ASTERIQS pushes the performances of diamond based thermal sensors to unprecedented sensitivities in the 10 μK/Hz1/2 range combined with sub-10 nm spatial resolution.
In WP6, USTUTT receives a sensor for caspase 8- activity from the Institute of Organic Chemistry and Biochemistry of the CAS (Czech Rep), which is an advance of the pH and redox potential sensor, which was already studied at USTUTT. USTUTT first characterizes this sensor in vitro by doing T1 measurements in the presence or absence of caspase 8. Control measurements are done with a non-cleavable analogue of the sensor.
Afterwards the plan is to introduce the sensor into mammalian cells, track the particles and do the T1 measurements in vivo. After the sensor is well characterized, USTUTT plans to induce apoptosis to detect caspase 8- activity with the sensor. This sensor will be – after its optimization- a prototype for the development of other sensors.
In WP7, USTUTT performs scanning NV magnetometry to investigate new nanoscale magnetic phenomena such as spin-liquids in RuCl3 and current distribution in WTe2.

UNIVERSITÄT DES SAARLANDES
The Quantum Optics group at the physics department of Saarland University (USAAR) has been founded in 2005. The scientific environment at the physics department in particular comprises 6 groups working in the field of quantum technologies. The quantum optics group has demonstrated experience in the fields of spectroscopy, quantum optics, quantum sensing and cavity quantum electrodynamics with colour centres in diamond and single photon nonlinear optics. Current research is focused on efficient narrow-band single photon sources at roomtemperature; generation and optical spectroscopy of novel colour centres in diamond; fabrication of diamond nanocrystals for efficient photon collection; coupling of colour centres to optical micro-cavities for enhanced singlephoton emission and realization of atom-photon-interfaces; design, fabrication and investigation of photonic crystal cavities in diamond; coherent all-optical control of spin states; and frequency conversion of single photons from the visible spectral range to the telecommunications band.
The group participates in several national and European research projects on quantum metrology, quantum sensing and quantum communication as well as on fundamental building blocks for these fields, e.g.:
- “Diamond Devices Enabled Metrology and Sensing (DIADEMS)”, EU, FP7.
- “Wavelength tunable advanced single photon sources (WASPS)”, EU, FP7.
- “Single-photon sources for quantum technologies (SIQUTE)”, EU, EMRP joint research proposal.
- “Mechanical and Opto-mechanical Interfaces for Single Color Centres in Diamond (FOR-1493)”, DFG, Germany.
Role in project
ASTERIQS project benefits from the group’s expertise in production and investigation of micro- and nanophotonic structures in diamond and investigation of novel color centres, in particular experience in the fields: room-temperature and cryogenic spectroscopy of single colour centres in diamond; efficient single photon sources based on colour centres in diamond; all-optical and microwave coherent single spin manipulation of single colour centres in diamond; fabrication of photonic crystal and open fiber-based cavities for colour centre coupling; employing microcavities to enhance magnetic sensing technologies. The Quantum Optics Group contributes to the project within WPs 3 and 5:
In WP3 USAAR leads task 3.3 and fabricate miniaturized, monolithic diamond cavities for enhancing the IR absorption on the NV centre singlet transition with the goal of realizing a compact magnetic field sensor with high contrast measurement signals. Here, the cavity consists of a heavily NV-doped diamond slab with polished side facets which allow for total-internal reflection of both pump and absorption light. Both light fields are evanescently coupled into the slab via a high-index coupling prism. One facet of the slab will feature a curved surface produced by microfabrication techniques to yield a stable cavity operation. USAAR investigates the samples and demonstrate evanescent coupling to the cavity and the magnetic field sensing capability of this approach. Further, USAAR develops, fabricates, and tests planar directional antennas based on a very thin diamond membrane embedded in metallic and dielectric thin films for broad-band, room-temperature enhancement of the emission and the collection of the fluorescence light. The spatial emission pattern might be designed to largely overlap with Gaussian modes, facilitating coupling to low-NA optics and optical fibers. USAAR will fabricate such antenna samples and will verify their operation and photon collection efficiency. For the latter approach, USAAR will closely collaborate with partners BOSCH and UNIBAS.
In WP5 USAAR contributes to task 5.1 with investigations of SiV centres for all-optical magnetometry in high magnetic fields of several tesla (with UNIBAS); measurements of pressure and magnetic fields in diamond anvil cells via all-optical methods using ensembles of SiV centres in diamond; and, together with E6, employing laser cutting and thinning to fabricate thin, strongly SiV-doped samples for pressure sensing as well as studies of spectroscopic properties of these SiV ensembles under high stress for sensing. For these investigations USAAR makes use of the fact that the electronic levels of SiV centres are strongly susceptible to external fields, temperature and local strain. Interestingly, the SiV’s spin degrees of freedom can be manipulated all-optically, without the need for microwave radiation. The centre of the SiV zero phonon line transition can be determined from spectroscopic measurements or based on coherent effects (e.g. spectral hole burning or coherent population trapping), which will be exploited here. As the SiV spin coherence time is limited by photon-driven transitions, high-sensitivity measurements are limited to ultra-low temperatures (~100 mK). An alternative system is color centres of similarly advantageous optical properties but larger ground state splitting suppressing the phononic decoherence effects, such as the recently discovered SnV centres. Consequently, within task 5.2 USAAR explores all-optical spin control and long spin coherence times of SnV centres with the aim of exploiting these for magnetic field and pressure sensing at elevated temperatures as compared to SiV centres (liquid He temperatures).

The Fraunhofer Institute for Applied Solid State Physics (IAF) is a leading science and technology centre in the field of micro and nano-structured compound semiconductors and devices made from synthetic diamond. Research and development are focused on micro and optoelectronic circuits, modules and systems for applications in safety, security and communication systems as well as for medical applications and environmental protection. The institute features a cutting-edge semiconductor process line, thus being able to provide leading edge devices, circuits and modules with the highest functionalities as prototypes or in small quantities. Our national and international partners in research and technology are the Federal Ministry of Defence (BMVg), the Federal Ministry of Education and Research (BMBF), national state governments, the European Commission, and industrial enterprises. The Institute was founded in 1957 and now has a total staff of 280 scientists, engineers and technicians. Our annual budget amounts to 28 million €. The IAF is one of the 60 research institutes of the Fraunhofer-Gesellschaft and is member of the Fraunhofer Alliance for Microelectronics (VμE) and the Fraunhofer Alliance for Defence and Security
Research (VVS). The Diamond Research Department led by C.E. Nebel and consists of 25 members. The diamond laboratory is equipped with 10 plasma-enhanced CVD (PECVD) reactors (diamond growth), state of the art technology and characterization tools. The team has developed outstanding expertise in a) homoepitaxial growth of PECVD diamond, in b) diamond related technologies like polishing, cutting, etching, bonding, and in c) fabrication of IR windows and cooling systems from diamond for laser applications. The team growth utra-pure diamond, atomically flat diamond, isotopically enriched diamond and doped (boron- and phosphorus) as well as intrinsic diamond. It has developed a method to generate 3D diamond structures by growth.
Role in project
In this project IAF apply their diamond homoepitaxial technology to grow ultra-pure isotopically enriched diamond films. Focussed areas are nitrogen delta-doping of atomically flat (111) oriented diamond layers.
Optimization of high-density nitrogen doping (> 1018 cm-3) to improve the nitrogen (P1) to NV conversion. In addition, the bottom-up growth technique of diamond tips and of (111)-oriented surfaces on (100) substrates are implemented, optimized and characterized at IAF. To generate single crystalline diamond tips, IAF also applies oxygen based ICP etching for the fabrication of tips in the nano-meter regime with NV in the very tip for magnetometry. These tips are singulated by a laser cutting step and mounted on AFM cantilevers for application and characterization by their colleagues. The use of thin diamond plates in insulating layers (DoI technique) is explored applying newly developed wafer-bonding technology in combination with planar thinning. Aims are to realize planar opto-electronic NV-arrays for 2 and 3D sensing. Main device interests are the development of sensing system for navigation and spatially resolved current measurements to characterize integrated circuits.

DEPARTMENT OF PHYSICS AND EARTH SCIENCES – NUCLEAR SOLID-STATE PHYSICS
The accelerator Lab in Leipzig operates three linear ion accelerators and provides all types of ions with kinetic energies between a few hundreds eV and several MeV. The lab is equipped with a semiconductor lab as well as several analytic methods. We developed special techniques to implant single ions with nm lateral resolution e.g. to produce shallow NV centres in diamond bulk materials or nano-clusters. The lab is associated with the IOM Leipzig institute and has admission to a 10 MeV electron accelerator. This provides an increase of the NV production yield.
Role in project
ULEI performs the implantation of all ion species in an energy range between a few eV to several MeV. ULEI provides a large number of material science techniques like plasma etching, ion beam analytics, annealing procedure and surface modification. ULEI performs quality test methods and try to install new specifications for a standardization of quantum materials. At least, ULEI is responsible for the production of color centres especially the NV centres with high lateral resolution. One goal is to investigate the mechanism of NV creation and their optimization in order to create NV centres deterministically.

EMMY NOETHER RESEARCH GROUP “QUANTUM SENSORS FOR LIFE SCIENCE”, WALTER SCHOTTKY INSTITUTE
The group of Friedemann Reinhard is an independent research group established in 2014, funded by the German Excellence Program “Emmy Noether”. This scheme is comparable to an ERC starting grant with respect to funding and responsibilities. The group is embedded into the Walter Schottky Institute (WSI), a central interdisciplinary institute of TUM. Initially founded for focused research on semiconductors, the institute has developed research on nanoscale quantum systems into one of its major activities over the past decade. Scientific work of the quantum sensing group is centred on nanoscale magnetic resonance using NV centres, in particular the development of magnetic resonance imaging at the single molecule level.
Role in project
TUM develops a novel approach to scanning-probe nano-sensing. It is based on planar diamond sensors  rather than nanofabricated tips. These planar sensors are approached into the sub-100nm proximity of arbitrary planar samples by 5D nanopositioning, guided by a far-field optical measurement of sensor-sample distance and tilt. This optical measurement is implemented in the same confocal microscope that serves as a readout tool for the NV Centre, using ellipsometry or optical interferometry. This approach aims to greatly reduce the technical barrier for groups entering NV-based scanning probe microscopy (NV-SPM), since it could transform scanning probe setups from a major independent instrument into a minor upgrade of an existing confocal microscope. It moreover promises to expand NV-SPM to applications requiring high-coherence NV centres, such as nanoscale magnetic resonance. TUM coordinates its effort with work on materials (E6, LSPM, IAF) to adapt sensor fabrication to the new technique. It leads development of a prototype setup to demonstrate the new technique, aiming to push its technology readiness level from ~TRL3 to ~TRL6. It employs this setup to replicate existing tip-based results on both NV-based near-field microscopy and magnetometry. It brings these results into the consortium and survey potential for novel applications in science and technology jointly with academic (CNRS-L2C) and industrial partners (ATTOCUBE, BOSCH, NVISION, SQUTEC, THALES). It provides measurements on its prototype setup to these groups for benchmarks and demonstrations. If a clear use case is identified, TUM seeks to either found a spin-off company to bring the technique to the market or transfer it to the industrial partners in a licensing scheme.

The Ecole normale supérieure Paris-Saclay (ENS Paris-Saclay, the operating name of the legal entity Ecole normale supérieure de Cachan) is a public institution of research and higher education, who covers a wide spectrum in science, engineering and humanities.
ENS Paris-Saclay started a research activity on NV centres more than 15 years ago, with the first realization of practical quantum cryptography testbeds and single-photon interference based on the photoluminescence of a single NV Centre. This knowledge was then applied to build NV-based magnetometers. Members of ENS Paris-Saclay were involved in the STREP EQUIND “Engineered Quantum Information in Nanostructured Diamond” (2007-2011) of the FP6 program, with Jean-François Roch as the coordinator, and in the FET-Open DIADEMS project.
Role in project
- Record the NV spin resonance under high pressure at both room- and low-temperature, by adaptation of an Attocube cryostat equipped with a superconducting vector magnet (WP5).
- Perform optical spectroscopy of the NV Centre investigated under high strain conditions, at both room temperature and cryogenic temperature, to develop a fundamental understanding of the effect of strain of the NV optical and spin properties (WP5).
- Use a dedicated FIB machine to create NV centres in diamond anvils by ion implantation and optimize their luminescence collection efficiency in realistic conditions associated to a diamond anvil cell environment(WP5).
- Characterize the NV Centre doping in overgrown layers on a single-crystal substrate with a millimeter size (WP2). The optimized sample hosting NV centres at a controllable depth will then be cut and polished into the Boehler-Almax anvil geometry. The goal is to integrate these anvils into a diamond anvil cell that can be operated above 100 GPa (WP5).
- Use the NV magnetic sensitivity to probe the magnetic and superconducting properties of iron and various hydrogen-rich compounds (WP7).
