Controlling and reversing the transition from classical diffusive to quantum ballistic transport in a quantum walk by driving the coin
Peng Xue, Barry C. Sanders
We show that the standard quantum-walk quantum-to-classical transition, characterized by ballistic-to-diffusive spreading of the walker's position, can be controlled by externally…
Non-Markovian Dynamics of Spin Squeezing
Peng Xue
We evaluate the spin squeezing dynamics of N independent spin-1/2 particles with exchange symmetry. Each spin interacts with its own reservoir, and the reservoirs are independently…
Spin Squeezing Property of Weighted Graph States
Peng Xue
We study the spin squeezing property of weighted graph states, which can be used to improve the sensitivity in interferometry. Decoherence reduces the spin squeezing property but t…
Probing multipartite entanglement in a coupled Jaynes-Cummings system
Peng Xue, Zbigniew Ficek, Barry C. Sanders
We show how to probe multipartite entanglement in coupled Jaynes-Cummings cells where the degrees of freedom are the electronic energies of each of the atoms in separate si…
Non-Markovian Decoherent Quantum Walks
Peng Xue, Yongsheng Zhang
Quantum walk acts obviously different from its classical counterpart, but decoherence will lessen and close the gap between them. To understand this process, it is necessary to inv…
Two quantum walkers sharing coins
Peng Xue, Barry C. Sanders
We consider two independent quantum walks on separate lines augmented by partial or full swapping of coins after each step. For classical random walks, swapping or not swapping coi…
