Phys. Rev. A 69, 050301(R) (2004) [4 pages]Geometric manipulation of the quantum states of two-level atoms
Manipulation of the quantum states of two-level atoms has been investigated using laser-controlled geometric phase change, which has the potential to build robust quantum logic gates for quantum computing. For a qubit based on two electronic transition levels of an atom, two basic quantum operations that can make any universal single qubit gate have been designed employing resonant laser pulses. An operation equivalent to a phase gate has been demonstrated using Tm3+ doped in a yttrium aluminum garnet crystal. © 2004 The American Physical Society URL:
