Periodic Reporting for period 1 - QuMicro (Quantum Microwave Detection with Diamond Spins)
Période du rapport: 2022-04-01 au 2023-03-31
The project objectives are as follows:
1) A thorough demonstration of the quantum heterodyne measurement principle.
2) The development of tailored quantum microwave detection protocols usable for commercial applications.
3) A fully self-contained quantum heterodyne microwave detector system technology.
4) Development of entanglement-based sensing methodology.
The project research work addressed 3 scientific work-packages and1 management WP, and this in particular:
WP1 Quantum Microwave Detector System Architecture
WP2 Materials and Microstructures
WP3 Quantum Dynamics and Protocols
Although there was only one deliverable in this period, which was timely submitted (D1.1 Test device architecture, M12), all WPs progressed towards the project goal, i.e. to develop a MW sensing platform using quantum heterodyne detection based on photoelectric detection of magnetic resonances, a breakthrough concept that we are applying in the QuMicro project.

As a highlight, we have demonstrated first MW detectors with a high bandwidth, of 25 GHz with frequency resolution down to 1 MHz, a millisecond temporal resolution and a large dynamic range (40 dB). The work has been upgraded by using photoelectric detection (Appl. Phys. Lett. 122, 19400, 2023). There were further achievements, described in individual WPs.
The project objectives relate to two main domains:
A. Research and development activities leading to demonstration of a novel concept of MW sensors, based on quantum effects, allowing to reach high frequency bandwidth, targeting 5G and 6G applications, high spectral resolution and compact design. The proposed device is based upon implementing the photoelectrical readout of NV centres in diamond, benchmarked with optical readout. The photoelectric readout should lead to higher signal/noise ratio and at the same time allowing a higher device integrability and compactness.
B. In parallel with the development of quantum heterodyne detection, we are exploring novel type of sensing platform, using quantum entanglement. The proposed methodology is based on quantum phase transitions based on many-body effects. When working at quantum critical points, marking passage from one to another quantum phases, extremely small external perturbances, such as electromagnetic field can lead to phase transitions, that are then detected. NV electron spin interaction serve as a many-body quantum system.
