Offer Description
The Nobel prize 2022 crowned the work realized by Alain Aspect on entangled photon pairs more than 40 years ago. Here we propose to exploit the specific quantum nature of single photons and photon pairs for enhancing fluorimetric applications. Our goal is twofold:
A) Enhanced fluorimetry in the two photon regime*.
When pairs of photons of frequencies f1/f2 resulting from a biexcitonic or cascade process are emitted by an individual fluorophore in a short lapse of time T, superposed to a continuous background noise, the signal/noise ratio associated to their joint detection is equal to C12.T/((S1.T).(S2.T)) with C the non-accidental coincidence rate, and S1/2 the rate of single detections at frequencies f1/f2. It increases proportionally to the inverse of T which can become very large for small values of T. This technique is promising regarding metrological performances of conventional fluorimetry, in the low intensity regime.
B) New anti-counterfeiting strategies based on quantum signature**.
Our second goal, roughly expressed, is to conceive quantum filigrans (filigrees) based on the specific optical response of well-chosen fluorophores, in the single photon regime (among others in the quantum strong-coupling regime). Like its classical counterpart, a quantum filigran is characterised by an optical response that is difficult to reproduce and/or to mimic.
Here we propose to identify specific quantum properties of the new types of fluorophores manufactured in the framework of the Artemis*** project in order to conceive new markers aimed at preventing counterfeiting, with potential applications to anti-counterfeiting in art and industry for instance.
Both techniques are promising regarding metrological performances of conventional fluorimetry, in the low intensity regime, with potential applications in tracing and marking**.
