Nonadiabatic geometric quantum computation
Z.S. Wang,Chunfeng Wu,Xun-Li Feng,Leong Chuan Kwek,Leong Chuan Kwek,Choy Heng Lai,Choo Hiap Oh,Vlatko Vedral,Vlatko Vedral +8 more
TL;DR: In this article, a different way to realize nonadiabatic geometric quantum computation is proposed by varying parameters in the Hamiltonian for nuclear-magnetic resonance, where the dynamical and geometric phases are implemented separately without the usual operational process.
Journal ArticleDOI
Scheme for unconventional geometric quantum computation in cavity QED
TL;DR: In this paper, the authors presented a scheme for implementing the unconventional geometric two-qubit phase gate with nonzero dynamical phase based on two-channel Raman interaction of two atoms in a cavity.
Journal ArticleDOI
Geometric phase induced by quantum nonlocality
Z.S. Wang,Chunfeng Wu,Xun-Li Feng,Leong Chuan Kwek,Leong Chuan Kwek,Choy Heng Lai,Choo Hiap Oh,Vlatko Vedral,Vlatko Vedral +8 more
TL;DR: By analyzing an instructive example, for testing many concepts and approaches in quantum mechanics, of a one-dimensional quantum problem with moving infinite square-well, Wang et al. as discussed by the authors define geometric phase of the physical system and find that there exist three dynamical phases from the energy, the momentum and local change in spatial boundary condition respectively.
Journal ArticleDOI
Unconventional geometric quantum computation in a two-mode cavity
Chunfeng Wu,Chunfeng Wu,Z.S. Wang,Xun-Li Feng,Hsi-Sheng Goan,Leong Chuan Kwek,Leong Chuan Kwek,Choy Heng Lai,Choo Hiap Oh +8 more
TL;DR: In this paper, the authors proposed a two-qubit phase gate with metastable states of the atom and hence is not affected by spontaneous emission, and the effect of cavity decay on the gate is investigated.
Journal ArticleDOI
Quantum tunneling via quantum geometric phase
TL;DR: In this article, a new geometric phase is proposed by considering both energy and momentum conservation, where the corresponding dynamical phases have two parts differently from the conventional calculations for the phase.
