Performance of Coherent Frequency-Shift Keying for Classical Communication \\ on Quantum Channels
Matteo Rosati
We evaluate the performance of coherent frequency-shift keying (CFSK) alphabets for communication on quantum channels. We show that, contrarily to what previously thought, the squa…
Reinforcement-learning calibration of coherent-state receivers on variable-loss optical channels
Matias Bilkis, Matteo Rosati, John Calsamiglia
We study the problem of calibrating a quantum receiver for optical coherent states when transmitted on a quantum optical channel with variable transmissivity, a common model for lo…
Real-time calibration of coherent-state receivers: learning by trial and error
M. Bilkis, M. Rosati, R. Morral Yepes +1
The optimal discrimination of coherent states of light with current technology is a key problem in classical and quantum communication, whose solution would enable the realization…
Accessible coherence in open quantum system dynamics
María García Díaz, Benjamin Desef, Matteo Rosati +5
Quantum coherence generated in a physical process can only be cast as a potentially useful resource if its effects can be detected at a later time. Recently, the notion of non-cohe…
Beyond the swap test: optimal estimation of quantum state overlap
Marco Fanizza, Matteo Rosati, Michalis Skotiniotis +2
We study the estimation of the overlap between two unknown pure quantum states of a finite dimensional system, given and copies of each type. This is a fundamental primitiv…
Using and reusing coherence to realize quantum processes
María García Díaz, Kun Fang, Xin Wang +4
Coherent superposition is a key feature of quantum mechanics that underlies the advantage of quantum technologies over their classical counterparts. Recently, coherence has been re…
