Quantum Enhanced Photonic Integrated Sensors For Metrology

Key optical and optomechanical functionalities on a single chip.

PROJECT AIM

Photonic quantum enhanced sensors at the next level of integration and usability

Sensors are ubiquitous in modern society. Over the years they expanded their field of use from scientific exploration to consumer electronics, and the sensor market evolved accordingly being now multi.billion euro in size. Quantum enhanced sensors hold the promise to outperform classical sensors and revolutionize the way we measure physical quantifies.

QUANTIFY overall objective consists in bringing photonic quantum enhanced sensors at the next level of integration and usability. Specifically, the project wants develop the essential building blocks and novel quantum enhanced techniques for future chip scale optical clocks, optically pumped magnetometers and optomechanical temperature sensors.

PROJECT AIM

Develop a novel optical probe

QUANTIFY will introduce a novel optical procbe: a photonic integrated squeezed light source, to increase the performance of the two photon optical clock and of the optically pumped magnetometer beyond classical capabilities.

Furthermore, the photonics integrated squeezed light source will have impact beyond this project, being an important step for realising a universal quantum computer based on photonics.

LATEST TOPICS

Pertinence of the objectives to the european work program topic

QUANTIFY will: use quantum states of light and matter to show disruptive progresses in three types of sensors: magnetometers, optical clocks and thermometers; develop ad-hoc metrology systems to benchmark performance and reliability of the sensors; increase the TRL of the essential elements for the miniaturization of such quantum devices and integrated laser technology; leverage the most suitable photonic platform for each sub-component: III-IV semiconductors for light emission, LNOI for squeezed state generation and efficient light modulation, SiN for low-loss circuites and high finesse lasercavities and GaP for optomechanical photonic crystal cavities oscillators; adopt the most advanced method for heterogeneous integration of such components (µTP) to bring all such functionalities on-chip.

All these objectives will allow a drastic reduction of SWaP and increased efficiency, reliability and robustness, greatly extending the field of application in new scenarios like small satellites or portable devices. 

OUR AMBITION

Develop the next generation of miniaturized, quantum enhanced, optical sensing devices to extend their usability in domains where low SWaP, reliability and reproducibility are of paramount importance.

To achieve this goal QUANTIFY will advance the stat-of-the-art in photonic integration, laser and quantum state miniaturization, quantum enhanced probing techniques and metrological protocols.
