Suppressing Weak Ising Couplings: Tailored Gates for Quantum Computation
arXiv:quant-ph/0307050 · doi:10.1016/S0375-9601(03)01130-7
Abstract
I describe the use of techniques based on composite rotations to develop controlled phase gates in which the effects of weak Ising couplings are suppressed. A tailored composite phase gate is described which both suppresses weak couplings and is relatively insensitive to systematic errors in the size of strong couplings.
