Superconducting Quantum Computing without Switches
Marc J. Feldman, Xingxiang Zhou
This paper presents a very simple architecture for a large-scale superconducting quantum computer. All of the SQUID qubits are fixed-coupled to a single large superconducting loop.

A general framework of nondistortion quantum interrogation
Zheng-Wei Zhou, Xingxiang Zhou, Xiu-Ding Lin +2
We present a general framework to study nondistortion quantum interrogation which preserves the internal state of the quantum object being detected. We obtain the necessary and suf…

High efficiency Nondistortion Quantum Interrogation of atoms in quantum superpositions
Xingxiang Zhou, Zheng-Wei Zhou, Guang-Can Guo +1
We consider the nondistortion quantum interrogation (NQI) of an atom prepared in a quantum superposition. By manipulating the polarization of the probe photon and making connection…
