Experimental implementation of high-fidelity unconventional geometric quantum gates using an NMR interferometer
Physical Review A. Atomic, Molecular, and Optical Physics
Following a key idea of unconventional geometric quantum computation developed earlier [Phys. Rev. Lett. 91, 197902 (2003)], here we propose a more general scheme in such an intriguing way: γ_d=α_g+ηγ _g, where γ_d and γ_g are respectively the dynamic and geometric phases accumulated in the quantum gate operation, with η as a constant and α_g being dependent only on the geometric feature of the operation. More arrestingly, we demonstrate the first experiment to implement a universal set of such
... kind of generalized unconventional geometric quantum gates with high fidelity in an NMR system.
