Evidence that All States Are Unitarily Equivalent to X States of the Same Entanglement
Samuel R. Hedemann
Strong numerical evidence is presented suggesting that all two-qubit mixed states are equivalent to X states by a single entanglement-preserving unitary (EPU) transformation, so th…
Inverse Engineering Control in Open Quantum Systems
Jun Jing, Lian-Ao Wu, Marcelo S. Sarandy +1
We propose a scheme for inverse engineering control in open quantum systems. Starting from an undetermined time evolution operator, a time-dependent Hamiltonian is derived in order…
One Component Dynamical Equation and Noise Induced Adiabaticity
Jun Jing, Lian-Ao Wu, Ting Yu +3
The adiabatic theorem addresses the dynamics of a target instantaneous eigenstate of a time-dependent Hamiltonian. We use a Feshbach P-Q partitioning technique to derive a closed o…
Restoration of Quantum State in Dephasing Channel
Xinyu Zhao, Samuel R. Hedemann, Ting Yu
In this paper, we propose an explicit scheme to fully recover a multiple-qubit state subject to a phase damping noise. We establish the theoretical framework and the operational pr…
