Ordering Matters: Structure, Accuracy and Gate Cost in Second-Order Suzuki Product Formulas
Matthew A Lane, Dan E Browne
Product formula methods, particularly the second-order Suzuki decomposition, are an important tool for simulating quantum dynamics on quantum computers due to their simplicity and…
Continuous-time quantum walks for MAX-CUT are hot
Robert J. Banks, Ehsan Haque, Farah Nazef +21
By exploiting the link between time-independent Hamiltonians and thermalisation, heuristic predictions on the performance of continuous-time quantum walks for MAX-CUT are made. The…
Union-find quantum decoding without union-find
Sam J. Griffiths, Dan E. Browne
The union-find decoder is a leading algorithmic approach to the correction of quantum errors on the surface code, achieving code thresholds comparable to minimum-weight perfect mat…
A fault-tolerant variational quantum algorithm with limited T-depth
Hasan Sayginel, Francois Jamet, Abhishek Agarwal +2
We propose a variational quantum eigensolver (VQE) algorithm that uses a fault-tolerant gate-set, and is hence suitable for implementation on a future error-corrected quantum compu…
Extending Matchgate Simulation Methods to Universal Quantum Circuits
Avinash Mocherla, Lingling Lao, Dan E. Browne
Matchgates are a family of parity-preserving two-qubit gates, nearest-neighbour circuits of which are known to be classically simulable in polynomial time. In this work, we present…
Rapid quantum approaches for combinatorial optimisation inspired by optimal state-transfer
Robert J. Banks, Dan E. Browne, P. A. Warburton
We propose a new design heuristic to tackle combinatorial optimisation problems, inspired by Hamiltonians for optimal state-transfer. The result is a rapid approximate optimisation…
