Journal ArticleDOI
Minimum Rényi and Wehrl entropies at the output of bosonic channels
TL;DR: It is shown that the Renyi output entropies of integer orders z{>=}2 and the Wehrl output entropy are minimized when the channel input is a coherent state.
Journal ArticleDOI
Multiple-access bosonic communications
Brent J. Yen,Jeffrey H. Shapiro +1 more
TL;DR: It is shown that the sum-rate upper bound is achievable with a coherent-state encoding and that the entire region is asymptotically achievable in the limit of large mean input photon numbers.
Journal ArticleDOI
Optimal quantum states for image sensing in loss.
Ranjith Nair,Brent J. Yen +1 more
TL;DR: It is shown that a pure input state of light with the signal modes in a mixture of number states minimizes the cost among all ancilla-assisted parallel strategies.
Journal ArticleDOI
Classical capacity of free-space optical communication
Vittorio Giovannetti,Saikat Guha,Seth Lloyd,Lorenzo Maccone,Jeffrey H. Shapiro,Brent J. Yen,Horace P. Yuen +6 more
TL;DR: The classical-information capacity of lossy bosonic channels is studied, with emphasis on the far-field free space channel.
Journal ArticleDOI
Symmetric M -ary phase discrimination using quantum-optical probe states
TL;DR: In this paper, a theoretical study of minimum error probability discrimination with quantum-optical probe states is presented, where the probe state is allowed to have any number of signal and ancillary modes and to be pure or mixed.
