Experimental implementation of high-fidelity unconventional geometric quantum gates using NMR interferometer
J. Du, P. Zou, Z. D. Wang
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 intrig…

Geometric phases for non-degenerate and degenerate mixed states
K. Singh, D. M. Tong, K. Basu +2
This paper focuses on the geometric phase of general mixed states under unitary evolution. Here we analyze both non-degenerate as well as degenerate states. Starting with the non-d…
