A review of perfect quantum state transfer, from one to two and three dimensional arrays of qubits
Marzieh Asoudeh, Vahid Karimipour
In the light of recent advances in fabricating single layer quantum chips and a possible road toward development of multi-layer quantum chips, we review, in a detailed way, the sub…

Bending hyperplanes: nonlinear entanglement witnesses via envelopes of linear witnesses
AmirHossein Tangestaninejad, Vahid Karimipour
Entanglement witnesses (EWs) are fundamental tools for detecting entanglement. However traditional linear witnesses often fail to identify most of the entangled states. In this wor…

Exact Quantum Capacity of Decohering Channels in Arbitrary Dimensions
Shayan Roofeh, Vahid Karimipour
We derive exact analytical expressions for the quantum capacity of a broad subclasses of generalized dephasing channels of the form , where represents a…
