QUANTUM METROLOGY AND COHERENCE IN STRUCTURED ENVIRONMENTS

Operation co-funded by EU cohesion policy (European Regional Development Fund (ERDF)) under the programme Multi-regional Spain - ERDF (2014ES16RFOP002), managing authority: Subdirección General de Gestión del FEDER, de la Dirección General de Fondos Europeos del Ministerio de Hacienda.. The source names no beneficiary for this operation. Location: Spain. Budget: total eligible expenditure EUR 29,645; EU co-financing EUR 23,716 (co-financing rate 80%), as stated by the source. Runs 2019-01-01 to 2021-12-31. Source: Kohesio, EU cohesion policy projects managed by national and regional authorities (not CORDIS). Summary from Kohesio (English machine translation by the source): QUANTUM TECHNOLOGIES REPRESENT THE NEXT STEP FORWARD IN WHICH QUANTUM PROPERTIES SUCH AS COHERENCE AND ENTANGLEMENT WILL BE MASTERED TO IMPROVE AND ENHANCE OUR CLASSICAL WORLD. THE PROBLEM OF DECOHERENCE, DISSIPATION AND DELETERIOUS ENVIRONMENTAL PROCESSES IS THE PRINCIPAL HURDLE THAT THE DEVELOPMENT OF SUCH QUANTUM TECHNOLOGIES MUST OVERCOME IN ORDER TO BECOME SCALABLE AND MOVE BEYOND THE PROOF-OF-PRINCIPLE STAGE. EACH AND EVERY REALISATION OF A PHYSICAL QUBIT IN THE REALM OF QUANTUM TECHNOLOGIES WILL UNAVOIDABLY SUFFER FROM INTERACTIONS WITH THEIR UNCONTROLLABLE ENVIRONMENT. IN THE EARLY DAYS OF THE DEVELOPMENT OF QUANTUM TECHNOLOGIES, IT WAS POSSIBLE TO MODEL THIS INTERACTION AS RESULTING FROM WHITE NOISE DISREGARDING OTHER CONTRIBUTIONS. THE ADVANCES IN DEVELOPMENT OF QUBIT IMPLEMENTATIONS AND IN THE LIGHT OF THEIR SCALABILITY, IT BECOMES INCREASINGLY APPARENT THAT THE REMAINING RELEVANT NOISE SOURCES ORIGINATE FROM POSSIBLY STRONG COUPLING TO STRUCTURED ENVIRONMENTS, WHICH WILL TYPICALLY GIVE RISE TO NON-MARKOVIAN EFFECTS. QUANTUM SENSING (QS) OR METROLOGY EXPLOITS PHYSICAL LAWS GOVERNING INDIVIDUAL QUANTUM SYSTEMS AND CORRELATIONS BETWEEN THEM, TO MEASURE PHYSICAL QUANTITIES WITH HIGH PRECISION. RECENTLY, AN APPRECIATION OF THE VAST POTENTIAL FOR A VARIETY OF APPLICATIONS, INCLUDING MAGNETIC AND ELECTRIC FIELD DETECTION, PRESSURE AND TEMPERATURE SENSORS, AND IMAGING AT THE NANOSCALE, HAS POSITIONED QS AT THE CENTRE OF QUANTUM SCIENCE AND TECHNOLOGY. QS IS A RAPIDLY GROWING FIELD, WITH THE MOST COMMON IMPLEMENTATION PLATFORMS BEING SPIN QUBITS AND TRAPPED IONS. ACCORDINGLY, SMALL QUANTUM DEVICES ARE EXPECTED TO BECOME A LEADING TECHNOLOGY WITHIN THE COMING YEARS. HOWEVER, THE BASIC SCIENCE SUPPORTING QUANTUM TECHNOLOGIES MUST FIRST TACKLE THE ISSUE OF SCALABILITY. THERE ARE SOME FUNDAMENTAL PROBLEMS IN INTERACTING DISORDERED MATERIALS, WHERE QUANTUM EFFECTS ARE RELEVANT, WHICH ARE STILL FAR FROM BEING UNDERSTOOD OWING TO THE COMPLEXITY OF ACHIEVING A FULL [shortened; the full text is on the Kohesio page]
