Quantum walk on a chimera graph

Shu Xu, Xiangxiang Sun, Jizhou Wu +3

We analyze a continuous-time quantum walk on a chimera graph, which is a graph of choice for designing quantum annealers, and we discover beautiful quantum-walk features such as lo…

Entanglement-assisted capacities of time-correlated amplitude-damping channel

Nigum Arshed, A. H. Toor

We calculate the information capacities of a time-correlated amplitude-damping channel, provided the sender and receiver share prior entanglement. Our analytical results show that…

Quantum capacity of an amplitude-damping channel with memory

Rabia Jahangir, Nigum Arshed, A. H. Toor

We calculate the quantum capacity of an amplitude-damping channel with time correlated Markov noise, for two channel uses. Our results show that memory of the channel increases it'…

Channel Capacities of an Exactly Solvable Spin-Star System

N. Arshed, A. H. Toor, D. A. Lidar

We calculate the entanglement-assisted and unassisted channel capacities of an exactly solvable spin star system, which models the quantum dephasing channel. The capacities for thi…

Entanlement-Assisted Classical Capacity of Quantum Channels with Correlated Noise

Nigum Arshed, A. H. Toor

We calculate the entanglement-assisted classical capacity of symmetric and asymmetric Pauli channels where two consecutive uses of the channels are correlated. It is evident from o…
