Nonadiabatic conditional geometric phase shift with NMR.
A conditional geometric phase shift gate, which is fault tolerant to certain types of errors due to its geometric nature, was realized recently via nuclear magnetic resonance (NMR) under adiabatic conditions. However, in quantum computation, everything must be completed within the decoherence time. The adiabatic condition makes any fast conditional Berry phase (cyclic adiabatic geometric phase)...

A conditional geometric phase shift gate, which is fault tolerant to certain types of errors due to its geometric nature, was realized recently via nuclear magnetic resonance(NMR) under adiabatic conditions. By the adiabatic requirement, the result is inexact unless the Hamiltonian changes extremely slowly. However, in quantum computation, everything must be completed within the decoherence tim...

متن کاملOn the nonadiabatic conditional geometrical phase with NMR
Wang Xiang-bin∗ Much long before the appearing time of the Comment [1], the main issue addresed there had been resolved already. Our correction to Eq.(11) in the Letter [2] first appeared in quant-ph/0101038(v4 and onwards), then appeared again in the extended version, quantph/0108111, and were finalized in ref [3](Erratum: PRL, 88, 179901(2002)). Surprisingly, in the Comment, Cen et al have ne...
متن کاملNonadiabatic Geometric Phase in Quaternionic Hilbert Space
We develop the theory of the nonadiabatic geometric phase, in both the Abelian and non-Abelian cases, in quaternionic Hilbert space.
