Tackling Systematic Errors in Quantum Logic Gates with Composite Rotations
H. K. Cummins, G. Llewellyn, J. A. Jones
We describe the use of composite rotations to combat systematic errors in single qubit quantum logic gates and discuss three families of composite rotations which can be used to co…

Approximate Quantum Cloning with Nuclear Magnetic Resonance
H. K. Cummins, C. Jones, A. Furze +4
Here we describe a Nuclear Magnetic Resonance (NMR) experiment that uses a three qubit NMR device to implement the one to two approximate quantum cloning network of Buzek et al.

Resonance Offset Tailored Pulses for NMR Quantum Computation
H. K. Cummins, J. A. Jones
We describe novel composite pulse sequences which act as general rotors and thus are suitable for nuclear magnetic resonance (NMR) quantum computation. The Resonance Offset Tailori…
