Proof of the Gaussian maximizers conjecture for the communication capacity of noisy heterodyne measurements
A. S. Holevo, S. N. Filippov
Basing on recently developed convex programming framework in the paper [arXiv:2204.10626], we provide a proof for a long-standing conjecture on optimality of Gaussian encondings fo…

Log-Sobolev inequality and proof of Hypothesis of the Gaussian Maximizers for the capacity of quantum noisy homodyning
A. S. Holevo
In the present paper we give proof that the information-transmission capacity of the approximate position measurement with the oscillator energy constraint, which underlies noisy G…
