A superconducting cavity bus for single Nitrogen Vacancy defect centres in diamond

J. Twamley, S. D. Barrett

Circuit-QED has demonstrated very strong coupling between individual microwave photons trapped in a superconducting coplanar resonator and nearby superconducting qubits. In this wo…

Error Correction and Degeneracy in Surface Codes Suffering Loss

T. M. Stace, S. D. Barrett

Many proposals for quantum information processing are subject to detectable loss errors. In this paper, we give a detailed account of recent results in which we showed that topolog…

Continuous-variables entanglement purification with atomic systems

Stojan Rebic, Stefano Mancini, Giovanna Morigi +1

We present a proposal for entanglement purification of the continuous-variable quantum state of two propagating optical fields. The scheme is based on letting each field interact w…

Vectorization of quantum operations and its use

Alexei Gilchrist, Daniel R. Terno, Christopher J. Wood

We give a detailed exposition of the "vectorized" notation for dealing with quantum operations. This notation is used to highlight the relationships between representations of comp…

Anyonic Quantum Walks

Gavin K. Brennen, Demosthenes Ellinas, Viv Kendon +3

The one dimensional quantum walk of anyonic systems is presented. The anyonic walker performs braiding operations with stationary anyons of the same type ordered canonically on the…

Black-box Hamiltonian simulation and unitary implementation

Dominic W. Berry, Andrew M. Childs

We present general methods for simulating black-box Hamiltonians using quantum walks. These techniques have two main applications: simulating sparse Hamiltonians and implementing b…
