Increase of entanglement by local PT -symmetric operations
Shin-Liang Chen, Guang-Yin Chen, Yueh-Nan Chen
Entanglement plays a central role in the field of quantum information science. It is well known that the degree of entanglement cannot be increased under local operations. Here, we…
Quantum coherence in ultrastrong optomechanics
D. Hu, S. -Y. Huang, J. -Q. Liao +2
Ultrastrong light-matter interaction in an optomechanical system can result in nonlinear optical effects such as photon blockade. The system-bath couplings in such systems play an…
Multi-stability and condensation of exciton-polaritons below threshold
Jiun-Yi Lien, Yueh-Nan Chen, Natsuko Ishida +3
Exciton-polaritons can condense to a macroscopic quantum state through a non-equilibrium process of pumping and decay. In recent experiments, polariton condensates are used to obse…
Optimal control for fast and high-fidelity quantum gates in coupled superconducting flux qubits
Shang-Yu Huang, Hsi-Sheng Goan
We apply the quantum optimal control theory based on the Krotov method to implement single-qubit and gates and two-qubit CNOT gates for inductively coupled superconducting…
Optimal control of quantum gates in an exactly solvable non-Markovian open quantum bit system
Jung-Shen Tai, Kuan-Ting Lin, Hsi-Sheng Goan
We apply quantum optimal control theory (QOCT) to an exactly solvable non-Markovian open quantum bit (qubit) system to achieve state-independent quantum control and construct high-…
Surface plasmons in a metal nanowire coupled to colloidal quantum dots: Scattering properties and quantum entanglement
Guang-Yin Chen, Neill Lambert, Chung-Hsien Chou +2
We investigate coherent single surface-plasmon transport in a metal nanowire strongly coupled to two colloidal quantum dots. Analytical expressions are obtained for the transmissio…
