Fast quantum logic by selective displacement of hot trapped ions

Abstract:
A report on the fast quantum logic by selective displacement of hot trapped ions was presented in the article. The effect of imperfections in a pair of π pulses which are used to implement a 'spin echo' to cancel correlated errors was also analyzed. It was found that whereas the pushing gate is not as resistant to imperfection as was supposed, it remains a significant candidate for ion trap quantum computing since it does not require ground state cooling.
