Sudden death of distillability in qutrit-qutrit systems
Wei Song, Lin Chen, Shi-Liang Zhu
We introduce the concept of distillability sudden death, i.e., free entangled states can evolve into non-distillable (bound entangled or separable) states in finite time under loca…
Large Scale Quantum Computation in an Anharmonic Linear Ion Trap
G. -D. Lin, S. -L. Zhu, R. Islam +5
We propose a large-scale quantum computer architecture by stabilizing a single large linear ion chain in a very simple trap geometry. By confining ions in an anharmonic linear trap…
A scheme for generating entangled cluster state of atomic ensembles
Ya-Fei Yu, Feng Mei, Zhi-Ming Zhang +1
It was shown in Ref.[Phys.Rev.A 77,045802(2008)] that the dynamics of a control atom and an atomic sample interacting dispersively with a cavity can be discribed by the Jaynes-Cumm…
Implementing topological quantum manipulation with superconducting circuits
Zheng-Yuan Xue, Shi-Liang Zhu, J. Q. You +1
A two-component fermion model with conventional two-body interactions was recently shown to have anyonic excitations. We here propose a scheme to physically implement this model by…
Quantum computation in decoherence-free subspace with superconducting devices
Zheng-Yuan Xue, Shi-Liang Zhu, Z. D. Wang
We propose a scheme to implement quantum computation in decoherence-free subspace with superconducting devices inside a cavity by unconventional geometric manipulation. Universal s…
