Quantum readout techniques and technologies (QUARTET)

QUARTET is exploiting quantum information to develop new powerful methods for the retrieval and recognition of classical data from a range of such physical systems. Specifically, it is exploiting quantum properties to enhance (1) the readout of classical data from digital memories (quantum reading); (2) the recognition of classical patterns (quantum pattern recognition); (3) the optical measurement of concentration in fragile biomedical samples (quantum bio-probing); (4) the microwave detection of target objects (microwave quantum illumination or quantum radar).

A cross-disciplinary team of researchers from the UK (York CS/NSC), Italy, Denmark, Austria and Finland, funded by the EU, is developing a series of experimental prototypes. These prototypes could open the way to much more powerful and radically new forms of information and detection technologies, with direct benefit for science and the wider society. 

Quantum reading may increase data-transfer rates and storage capacities of current digital memories. Quantum bio-probing and pattern recognition could have long-term applications in biology and medicine, allowing non-invasive analysis of very fragile biological samples or human tissues, and better recognition of hidden patterns associated with bacterial growths or cancerous cells. Quantum radar may have applications for detection and surveillance technology.
