Simulation of the spin-boson model with superconducting phase qubit coupled to a transmission line
Long-Bao Yu, Ning-Hua Tong, Zheng-Yuan Xue +2
Based on the rapid experimental developments of circuit QED, we propose a feasible scheme to simulate a spin-boson model with the superconducting circuits, which can be used to det…
An unconventional geometric phase gate with two nonresonant quantum dots trapped in a photonic crystal cavity
Jian-Qi Zhang, Ya-Fei Yu, Zhi-Ming Zhang
We propose a scheme for realizing a two-qubit controlled phase gate via an unconventional geometric phase with two nonresonant quantum dots trapped in a photonic crystal cavity. In…
Efficient Phase-Encoding Quantum Key Generation with Narrow-Band Single Photons
Hui Yan, Shi-Liang Zhu, Shengwang Du
We propose an efficient phase-encoding quantum secret key generation scheme with heralded narrow-band single photons. The key information is carried by the phase modulation directl…
An Experimental Proposal to Test Dynamic Quantum Non-locality with Single-Atom Interferometry
Shi-Liang Zhu, Zheng-Yuan Xue, Dan-Wei Zhang +1
Quantum non-locality based on the well-known Bell inequality is of kinematic nature. A different type of quantum non-locality, the non-locality of the quantum equation of motion, i…
Fast geometric gate operation of superconducting charge qubits in circuit QED
Zheng-Yuan Xue
A scheme for coupling superconducting charge qubits via a one-dimensional superconducting transmission line resonator is proposed. The qubits are working at their optimal points, w…
