The Magic Scroll: Leveraging biased noise to improve magic state cultivation in register-based architectures
Ian D. Thorvaldson, Jeffrey Marshall, Jack R. Craig +3
Multiple quantum computing platforms across neutral atoms [1], nitrogen vacancy centres [2, 3], gate-defined dots [4-6] and 14|15 phosphorus atom qubits [7, 8] in silicon are exper…
Optimisation-Free Recursive QAOA for the Binary Paint Shop Problem
Gary J Mooney, Jedwin Villanueva, Bhaskar Roy Radhan +3
The Quantum Approximate Optimisation Algorithm (QAOA) is a leading candidate for near-term quantum advantage, yet its practical impact is hindered by limited performance on symmetr…
Practical learning of multi-time statistics in open quantum systems
Gregory A. L. White, Lloyd C. L. Hollenberg, Charles D. Hill +1
Randomised measurements can efficiently characterise many-body quantum states by learning the expectation values of observables with low Pauli weights. In this paper, we generalise…
Unifying non-Markovian characterisation with an efficient and self-consistent framework
Gregory A. L. White, Petar Jurcevic, Charles D. Hill +1
Noise on quantum devices is much more complex than it is commonly given credit. Far from usual models of decoherence, nearly all quantum devices are plagued both by a continuum of…
Hybrid quantum optimization in the context of minimizing traffic congestion
Jedwin Villanueva, Gary J Mooney, Bhaskar Roy Bardhan +3
Traffic optimization on roads is a highly complex problem, with one important aspect being minimization of traffic congestion. By mapping to an Ising formulation of the traffic con…
Grover's algorithm in a four-qubit silicon processor above the fault-tolerant threshold
Ian Thorvaldson, Dean Poulos, Christian M. Moehle +15
Spin qubits in silicon are strong contenders for realizing a practical quantum computer. This technology has made remarkable progress with the demonstration of single and two-qubit…
