Quantum receiver for phase-shift keying at the single photon level
Jasminder S. Sidhu, Shuro Izumi, Jonas S. Neergaard-Nielsen +2
Quantum enhanced receivers are endowed with resources to achieve higher sensitivities than conventional technologies. For application in optical communications, they provide improv…
Adaptive generalized measurement for unambiguous state discrimination of quaternary phase-shift-keying coherent states
Shuro Izumi, Jonas S. Neergaard-Nielsen, Ulrik L. Andersen
Generalized quantum measurements identifying non-orthogonal states without ambiguity often play an indispensable role in various quantum applications. For such unambiguous state di…
Limit of Gaussian operations and measurements for Gaussian state discrimination, and its application to state comparison
David E. Roberson, Shuro Izumi, Wojciech Roga +3
We determine the optimal method of discriminating and comparing quantum states from a certain class of multimode Gaussian states and their mixtures when arbitrary global Gaussian o…
Experimental demonstration of a quantum receiver beating the standard quantum limit at the telecom wavelength
Shuro Izumi, Jonas S. Neergaard-Nielsen, Shigehito Miki +2
Discrimination of coherent states beyond the standard quantum limit (SQL) is an important tasknot only for quantum information processing but also for optical coherent communicatio…
