Compiling the 2D Fermi-Hubbard ground-state energy estimation algorithm for active volume quantum architectures
Harriet Apel, Athena Caesura, Carys Harvey +11
As quantum computing enters the early fault-tolerant era, circuit compilation choices will increasingly depend on details of the underlying architecture rather than solely optimizi…
Faster quantum chemistry simulations on a quantum computer with improved tensor factorization and active volume compilation
Athena Caesura, Cristian L. Cortes, William Pol +8
Electronic structure calculations of molecular systems are among the most promising applications for fault-tolerant quantum computing (FTQC) in quantum chemistry and drug design. H…
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…
A case study against QSVT: assessment of quantum phase estimation improved by signal processing techniques
Sean Greenaway, William Pol, Sukin Sim
In recent years, quantum algorithms have been proposed which use quantum phase estimation (QPE) coherently as a subroutine without measurement. In order to do this effectively, the…
