Scalable fault-tolerant quantum computation in DFS blocks
Zheng-Wei Zhou, Bo Yu, Xingxiang Zhou +2
We investigate how to concatenate different decoherence-free subspaces (DFSs) to realize scalable universal fault-tolerant quantum computation. Based on tunable interactions,…
Dispersive Manipulation of Paired Superconducting Qubits
Xingxiang Zhou, Michael Wulf, Zhengwei Zhou +2
We combine the ideas of qubit encoding and dispersive dynamics to enable robust and easy quantum information processing (QIP) on paired superconducting charge boxes sharing a commo…
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.
Quantum computation with un-tunable couplings
Xingxiang Zhou, Zheng-Wei Zhou, Guang-Can Guo +1
Most quantum computer realizations require the ability to apply local fields and tune the couplings between qubits, in order to realize single bit and two bit gates which are neces…
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…
