Non-adiabatic universal holonomic quantum gates    [PDF]

Utkan Güngördü, Yidun Wan, Mikio Nakahara
We propose a novel way of implementing non-adiabatic universal set of holonomic quantum gates using dynamical invariants, by Lie-algebraic methods. Unlike previous implementations, presented scheme does not rely on secondary methods such as double-loop or spin-echo and avoids associated experimental difficulties. It turns out that such gates exist purely in the non-adiabatic regime for these systems.
