A Sum-of-Squares Hierarchy with Quadratic Convergence for Quantum Channel Coding
Hoang Ta, Hoang Anh Tran
Computing the optimal success probability for transmitting classical messages through a single use of a quantum channel is NP-hard, even for two messages. An existing semidefinite…

Efficient Approximation of Quantum Channel Fidelity Exploiting Symmetry
Yeow Meng Chee, Hoang Ta, Van Khu Vu
Determining the optimal fidelity for the transmission of quantum information over noisy quantum channels is one of the central problems in quantum information theory. Recently, [Be…

A hierarchy of efficient bounds on quantum capacities exploiting symmetry
Omar Fawzi, Ala Shayeghi, Hoang Ta
Optimal rates for achieving an information processing task are often characterized in terms of regularized information measures. In many cases of quantum tasks, we do not know how…
