Optimal probabilistic storage and retrieval of unitary channels

M Sedlák, A Bisio, M Ziman - Physical review letters, 2019 - APS
We address the question of quantum memory storage for quantum dynamics. In particular,
we design an optimal protocol for N→ 1 probabilistic storage and retrieval of unitary …

Optimal quantum networks and one-shot entropies

G Chiribella, D Ebler - New Journal of Physics, 2016 - iopscience.iop.org
We develop a semidefinite programming method for the optimization of quantum networks,
including both causal networks and networks with indefinite causal structure. Our method …

Optimal universal programming of unitary gates

Y Yang, R Renner, G Chiribella - Physical review letters, 2020 - APS
A universal quantum processor is a device that takes as input a (quantum) program,
containing an encoding of an arbitrary unitary gate, and a (quantum) data register, on which …

A coding theorem for bipartite unitaries in distributed quantum computation

E Wakakuwa, A Soeda, M Murao - IEEE Transactions on …, 2017 - ieeexplore.ieee.org
We analyze implementations of bipartite unitaries by means of local operations and classical
communication (LOCC) assisted by shared entanglement. We employ concepts and …
