Optimized quantum algorithms for simulating the Schwinger effect
Angus Kan, Jessica Lemieux, Olga Okrut +1
The Schwinger model, which describes lattice quantum electrodynamics in space-time dimensions, provides a valuable framework to investigate fundamental aspects of quantum fie…
Reducing quantum resources for observable estimation with window-assisted coherent QPE
Harriet Apel, Cristian L. Cortes, Jessica Lemieux +1
Quantum Phase Estimation (QPE) routines are known to fail probabilistically even with perfect gates and input states. This effect stems from an incompatibility of finite-sized quan…
Multi-qubit Lattice Surgery Scheduling
Allyson Silva, Xiangyi Zhang, Zak Webb +7
Fault-tolerant quantum computation using two-dimensional topological quantum error correcting codes can benefit from multi-qubit long-range operations. By using simple commutation…
Quantum sampling algorithms for quantum state preparation and matrix block-encoding
Jessica Lemieux, Matteo Lostaglio, Sam Pallister +4
The problems of quantum state preparation and matrix block-encoding are ubiquitous in quantum computing: they are crucial parts of various quantum algorithms for the purpose for in…
