Mind the gap: Achieving a super-Grover quantum speedup by jumping to the end
Alexander M. Dalzell, Nicola Pancotti, Earl T. Campbell +1
We present a quantum algorithm that has rigorous runtime guarantees for several families of binary optimization problems, including Quadratic Unconstrained Binary Optimization (QUB…
Quantum Computation for Periodic Solids in Second Quantization
Aleksei V. Ivanov, Christoph Sünderhauf, Nicole Holzmann +4
In this work, we present a quantum algorithm for ground-state energy calculations of periodic solids on error-corrected quantum computers. The algorithm is based on the sparse qubi…
Parallel window decoding enables scalable fault tolerant quantum computation
Luka Skoric, Dan E. Browne, Kenton M. Barnes +2
Large-scale quantum computers have the potential to hold computational capabilities beyond conventional computers for certain problems. However, the physical qubits within a quantu…
Post-selection-free preparation of high-quality physical qubits
Ben Barber, Neil I. Gillespie, J. M. Taylor
Rapidly improving gate fidelities for coherent operations mean that errors in state preparation and measurement (SPAM) may become a dominant source of error for fault-tolerant oper…
Hierarchies of resources for measurement-based quantum computation
Markus Frembs, Sam Roberts, Earl T. Campbell +1
For certain restricted computational tasks, quantum mechanics provides a provable advantage over any possible classical implementation. Several of these results have been proven us…
Improved decoding of circuit noise and fragile boundaries of tailored surface codes
Oscar Higgott, Thomas C. Bohdanowicz, Aleksander Kubica +2
Realizing the full potential of quantum computation requires quantum error correction (QEC), with most recent breakthrough demonstrations of QEC using the surface code. QEC codes u…
