Quantum computation mediated by ancillary qudits and spin coherent states (2015)
Journal Article
Proctor, T. J., Dooley, S., & Kendon, V. (2015). Quantum computation mediated by ancillary qudits and spin coherent states. Physical Review A, 91(1), Article 012308. https://doi.org/10.1103/physreva.91.012308

Models of universal quantum computation in which the required interactions between register (computational) qubits are mediated by some ancillary system are highly relevant to experimental realizations of a quantum computer. We introduce such a unive... Read More about Quantum computation mediated by ancillary qudits and spin coherent states.

When does a physical system compute? (2014)
Journal Article
Horsman, C., Stepney, S., Wagner, R. C., & Kendon, V. (2014). When does a physical system compute?. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 470(2169), Article 20140182. https://doi.org/10.1098/rspa.2014.0182

Computing is a high-level process of a physical system. Recent interest in non-standard computing systems, including quantum and biological computers, has brought this physical basis of computing to the forefront. There has been, however, no consensu...

Minimal ancilla mediated quantum computation (2014)
Journal Article
Proctor, T. J., & Kendon, V. (2014). Minimal ancilla mediated quantum computation. EPJ Quantum Technology, 1(1), Article 13. https://doi.org/10.1140/epjqt13

Schemes of universal quantum computation in which the interactions between the computational elements, in a computational register, are mediated by some ancillary system are of interest due to their relevance to the physical implementation of a quant...

Nonreversal and nonrepeating quantum walks. (2014)
Journal Article
Proctor, T., Barr, K., Hanson, B., Martiel, S., Pavlovic, V., Bullivant, A., & Kendon, V. (2014). Nonreversal and nonrepeating quantum walks. Physical Review A, 89(4), Article 042332. https://doi.org/10.1103/physreva.89.042332

We introduce a variation of the discrete-time quantum walk, the nonreversal quantum walk, which does not step back onto a position that it has just occupied. This allows us to simulate a dimer and we achieve it by introducing a different type of coin... Read More about Nonreversal and nonrepeating quantum walks..
