Enhancing non-Markovianity by quantum feedback control
Numerical simulations show that the quantum-jump-based feedback control can be used to enhance the measure of non-Markovianity and can further be optimized by choosing appropriate feedback amplitude. Expand
Enhancing the absorption and energy transfer process via quantum entanglement
In the two-qubit initial state case, the initial entanglement between the donors can help to improve the absorption and energy transfer process for both the near-resonant and large-detuning cases. Expand
Protection of qubit-coherence on a Bloch sphere
Single qubit pure state is a fundamental resource in quantum information and quantum computation. Therefore, it is of great importance to protect the coherence of single qubits against decoherence.Expand
Protecting multipartite entanglement against weak-measurement-induced amplitude damping by local unitary operations
A scheme for protecting tripartite entanglement against decaying caused by weak-measurement-induced damping based on local pulse series, which suggests that the scheme is much simpler and feasible, which may warrant its experimental realization. Expand
Protecting remote atomic entanglement against spontaneous emission by separated photonic pulses
We study the entanglement dynamics between two spatially separated atoms trapped in two separate optical cavities. Based on cavity-assisted interactions between the atoms and separated photonicExpand
State-independent purity and fidelity of quantum operations
The purity and fidelity of quantum operations are of great importance in characterizing the quality of quantum operations. The currently available definitions of the purity and fidelity of quantumExpand
Optical simulation of a Popescu-Rohrlich Box
The comprehensive loophole opened by the results selection within “two-state vector formalism” may be another possible explanation of why post-quantum correlations are incompatible with quantum mechanics and seem not to exist in nature. Expand
