Scientific applications of quantum computing: challenges and opportunities
Bruno Camino, C. Richard A. Catlow, John Buckeridge +13
The predictive simulation of molecules and materials has had a broad and significant impact. It nevertheless remains constrained by the cost of accurately treating electronic corre…
Numerical methods for the simulation of quantum walks and quantum annealing
Asa Hopkins, Viv Kendon
It is known that Chebyshev based polynomial approximation gives a near-optimal rate of convergence for calculating a function of a Hermitian matrix. However, previous work has not…
Quantum annealing and condensed matter physics
Viv Kendon, Nicholas Chancellor
Quantum annealing leverages the properties of interacting quantum spin systems to solve computational problems, typically optimisation problems. Current hardware now has capabiliti…
Continuum Limits of Lazy Open Quantum Walks
Lara Janiurek, Viv Kendon
We derive the continuous spacetime limit of the one dimensional lazy discrete time quantum walk, obtaining explicit macroscopic evolution equations for a three state model in the p…
Heuristics for multi-stage quantum walks to find Ising ground states
Asa Hopkins, Viv Kendon
One way to approximate a quantum annealing schedule is to use multiple quantum walks chained together, without intermediate measurements, to produce a multi-stage quantum walk (MSQ…
Improving success probability in the LHZ parity embedding by computing with quantum walks
Jemma Bennett, Nicholas Chancellor, Viv Kendon +1
The LHZ parity embedding is one of the front-running methods for implementing difficult-to-engineer long-range interactions in quantum optimisation problems. Continuous-time quantu…
A Review and Collection of Metrics and Benchmarks for Quantum Computers: definitions, methodologies and software
Deep Lall, Abhishek Agarwal, Weixi Zhang +15
Quantum computers have the potential to provide an advantage over classical computers in a number of areas. Numerous metrics to benchmark the performance of quantum computers, rang…

Quantum computing promises to provide the next step up in computational power for diverse application areas. In this review, we examine the science behind the quantum hype, and the…
Quantum search with hybrid adiabatic-quantum walk algorithms and realistic noise
James G. Morley, Nicholas Chancellor, Sougato Bose +1
Computing using a continuous-time evolution, based on the natural interaction Hamiltonian of the quantum computer hardware, is a promising route to building useful quantum computer…
The quantum walk search algorithm: Factors affecting efficiency
Neil B. Lovett, Matthew Everitt, Robert M. Heath +1
We numerically study the quantum walk search algorithm of Shenvi, Kempe and Whaley [PRA \textbf{67} 052307] and the factors which affect its efficiency in finding an individual sta…
Thermal concurrence mixing in a 1D Ising model
D. Gunlycke, S. Bose, V. M. Kendon +1
We investigate the entanglement arising naturally in a 1D Ising chain in a magnetic field in an arbitrary direction. We find that for different temperatures, different orientations…
Persistence exponents in a 3D symmetric binary fluid mixture
V. M. Kendon, M. E. Cates, J-C. Desplat
The persistence exponent, theta, is defined by N_F sim t^theta, where t is the time since the start of the coarsening process and the "no-flip fraction", N_F, is the number of poin…
A scaling theory of 3D spinodal turbulence
V M Kendon
A new scaling theory for spinodal decomposition in the inertial hydrodynamic regime is presented. The scaling involves three relevant length scales, the domain size, the Taylor mic…
3D Spinodal Decomposition in the Inertial Regime
V. M. Kendon, J-C. Desplat, P. Bladon +1
We simulate late-stage coarsening of a 3D symmetric binary fluid using a lattice Boltzmann method. With reduced lengths and times l and t respectively (scales set by viscosity, den…
