Possible realization of entanglement, logical gates and quantum information transfer with superconducting-quantum-interference-device qubits in cavity QED
Chui-Ping Yang, Shih-I Chu, Siyuan Han
We present a scheme to achieve maximally entangled states, controlled phase-shift gate, and SWAP gate for two superconducting-quantum-interference-device (SQUID) qubits, by placing…
Coherent control of atomic spin currents in a double well
H. T. Ng, Shih-I Chu
We propose an experimental feasible method for controlling the atomic currents of a two-component Bose-Einstein condensate in a double well by applying an external field to the ato…
Steady-state entanglement in a double-well Bose-Einstein condensate through coupling to a superconducting resonator
H. T. Ng, Shih-I Chu
We consider a two-component Bose-Einstein condensate in a double-well potential, where the atoms are magnetically coupled to a single-mode of the microwave field inside a supercond…
Time-dependent localized Hartree-Fock density-functional linear response approach for photoionization of atomic excited states
Zhongyuan Zhou, Shih-I Chu
We present a time-dependent localized Hartree-Fock density-functional linear response approach for the treatment of photoionization of atomic systems. This approach employs a spin-…
Decoherence of a driven multilevel quantum system interacting with a multi-bath reservoir
Zhongyuan Zhou, Shih-I Chu, Siyuan Han
A general theory is presented for the treatment of decoherence of a multilevel quantum system (with many degrees of freedom) interacting with multi-bath reservoir and driven by ac…
A unified approach to realize universal quantum gates in a coupled two-qubit system with fixed always-on coupling
Zhongyuan Zhou, Shih-I Chu, Siyuan Han
We demonstrate that in a coupled two-qubit system any single-qubit gate can be decomposed into two conditional two-qubit gates and that any conditional two-qubit gate can be implem…
