Energy-constrained private and quantum capacities of quantum channels
Mark M. Wilde, Haoyu Qi
This paper establishes a general theory of energy-constrained quantum and private capacities of quantum channels. We begin by defining various energy-constrained communication task…
On the minimum output entropy of single-mode phase-insensitive Gaussian channels
Haoyu Qi, Mark M. Wilde, Saikat Guha
Recently de Palma et al. [IEEE Trans. Inf. Theory 63, 728 (2017)] proved---using Lagrange multiplier techniques---that under a non-zero input entropy constraint, a thermal state in…
Self-tallying Quantum Anonymous Voting
Qingle Wang, Chaohua Yu, Fei Gao +2
Anonymous voting is a voting method of hiding the link between a vote and a voter, the context of which ranges from governmental elections to decision making in small groups like c…
Capacities of Quantum Amplifier Channels
Haoyu Qi, Mark M. Wilde
Quantum amplifier channels are at the core of several physical processes. Not only do they model the optical process of spontaneous parametric down-conversion, but the transformati…
