Density functionals and Kohn-Sham potentials with minimal wavefunction preparations on a quantum computer

Thomas E. Baker, David Poulin

One of the potential applications of a quantum computer is solving quantum chemical systems. It is known that one of the fastest ways to obtain somewhat accurate solutions classica…

Entanglement and classical correlations at the doping-driven Mott transition in the two-dimensional Hubbard model

C. Walsh, P. Sémon, D. Poulin +2

Tools of quantum information theory offer a new perspective to characterize phases and phase transitions in interacting many-body quantum systems. The Hubbard model is the archetyp…

Resource estimate for quantum many-body ground-state preparation on a quantum computer

Jessica Lemieux, Guillaume Duclos-Cianci, David Sénéchal +1

We estimate the resources required to prepare the ground state of a quantum many-body system on a quantum computer of intermediate size. This estimate is made possible using a comb…

Efficient Quantum Walk Circuits for Metropolis-Hastings Algorithm

Jessica Lemieux, Bettina Heim, David Poulin +2

We present a detailed circuit implementation of Szegedy's quantization of the Metropolis-Hastings walk. This quantum walk is usually defined with respect to an oracle. We find that…

Fault-tolerant gates on hypergraph product codes

Anirudh Krishna, David Poulin

Hypergraph product codes are a class of quantum low density parity check (LDPC) codes discovered by Tillich and Zémor. These codes have a constant encoding rate and were recently s…

Topological wormholes

Anirudh Krishna, David Poulin

Locality plays a fundamental role in quantum computation but also severely restricts our ability to store and process quantum information. We argue that this restriction may be unw…
