Classical simulatability, entanglement breaking, and quantum computation thresholds

S. Virmani, Susana F. Huelga, Martin B. Plenio

We investigate the amount of noise required to turn a universal quantum gate set into one that can be efficiently modelled classically. This question is useful for providing upper…

Entangled states maximize the two qubit channel capacity for some Pauli channels with memory

C. Macchiavello, G. M. Palma, S. Virmani

We prove that a general upper bound on the maximal mutual information of quantum channels is saturated in the case of Pauli channels with an arbitrary degree of memory. For a subse…

Construction of extremal local positive operator-valued measures under symmetry

S. Virmani, M. B. Plenio

We study the local implementation of POVMs when we require only the faithful reproduction of the statistics of the measurement outcomes for all initial states. We first demonstrate…

The asymptotic relative entropy of entanglement

K. Audenaert, J. Eisert, E. Jane +3

We present an analytical formula for the asymptotic relative entropy of entanglement for Werner states of arbitrary dimension. We then demonstrate its validity using methods from c…

Optimal local discrimination of two multipartite pure states

S. Virmani, M. F. Sacchi, M. B. Plenio +1

In a recent paper, Walgate et. al. demonstrated that any two orthogonal multipartite pure states can be optimally distinguished using only local operations. We utilise their result…

Tripartite entanglement and quantum relative entropy

E. F. Galvao, M. B. Plenio, S. Virmani

We establish relations between tripartite pure state entanglement and additivity properties of the bipartite relative entropy of entanglement. Our results pertain to the asymptotic…
