Suppressing Weak Ising Couplings: Tailored Gates for Quantum Computation

Jonathan A. Jones

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.

Always on non-nearest-neighbour coupling in scalable quantum computing

Yong Hu, Zheng-Wei Zhou, Guang‐Can Guo

In many previous 'always-on' quantum computing (QC) schemes the non-nearest-neighbour couplings are often omitted because of their weak strength compared with the nearest-neighbour coupling. In this paper, we consider the problem of residual long-range interaction. We propose a QC scheme in which by the method of generalized 'barrier spin' encoding, the influence of the long-range coupling can be significantly suppressed. The universal quantum gates could be deterministically established. We also study the application of this scheme in a Josephson junction system.

Robust Ising gates for practical quantum computation

Jonathan A. Jones

I describe the use of techniques based on composite rotations to combat systematic errors in controlled phase gates, which form the basis of two-qubit quantum logic gates. Although developed and described within the context of nuclear magnetic resonanace quantum computing these sequences should be applicable to any implementation of quantum computation based on Ising couplings. In combination with existing single-qubit gates this provides a universal set of robust quantum logic gates.
