Bias-induced chiral current and topological blockadein triple quantum dots
YuanDong Wang, ZhenGang Zhu, JianHua Wei +1
We theoretically investigate the quantum transport properties of a triangular triple quantum dot (TTQD) ring connected with two reservoirs by means of analytical derivation and acc…
Macroscopic Quantum Criticality in a Circuit QED
Y. D. Wang, H. T. Quan, Yu-xi Liu +2
Cavity quantum electrodynamic (QED) is studied for two strongly-coupled charge qubits interacting with a single-mode quantized field, which is provided by a on-chip transmission li…
Quantum storage and information transfer with superconducting qubits
Y. D. Wang, Z. D. Wang, C. P. Sun
We design theoretically a new device to realize the general quantum storage based on dcSQUID charge qubits. The distinct advantages of our scheme are analyzed in comparison with ex…
Cooling of Nanomechanical Resonator Based on Periodical Coupling to Cooper Pair Box
P. Zhang, Y. D. Wang, C. P. Sun
We propose and study an active cooling mechanism for the nanomechanical resonator (NAMR) based on periodical coupling to a Cooper pair box (CPB), which is implemented by a designed…
Spin wave based quantum storage of electronic spin with a ring array of nuclear spins
Y. D. Wang, Y. Li, Z. Song +1
We propose a solid state based protocol to implement the universal quantum storage for electronic spin qubit. The quantum memory in this scheme is the spin wave excitation in the r…
A nonlinear mechanism of charge qubit decoherence in a lossy cavity: the quasi normal mode approach
Y. B. Gao, Y. D. Wang, C. P. Sun
In the viewpoint of quasi normal modes, we describe a novel decoherence mechanism of charge qubit of Josephson Junctions (JJ) in a lossy micro-cavity, which can appear in the reali…
