Computational Complexity in Electronic Structure
James D. Whitfield, Peter J. Love, Alan Aspuru-Guzik
In quantum chemistry, the price paid by all known efficient model chemistries is either the truncation of the Hilbert space or uncontrolled approximations. Theoretical computer sci…
Quantum Transport Enhancement by Time-Reversal Symmetry Breaking
Zoltan Zimboras, Mauro Faccin, Zoltan Kadar +3
Quantum mechanics still provides new unexpected effects when considering the transport of energy and information. Models of continuous time quantum walks, which implicitly use time…
Ground State Spin Logic
J. D. Whitfield, M. Faccin, J. D. Biamonte
Designing and optimizing cost functions and energy landscapes is a problem encountered in many fields of science and engineering. These landscapes and cost functions can be embedde…
Simulating chemistry efficiently on fault-tolerant quantum computers
N. Cody Jones, James D. Whitfield, Peter L. McMahon +4
Quantum computers can in principle simulate quantum physics exponentially faster than their classical counterparts, but some technical hurdles remain. Here we consider methods to m…
Introduction to Quantum Algorithms for Physics and Chemistry
Man-Hong Yung, James D. Whitfield, Sergio Boixo +2
In this introductory review, we focus on applications of quantum computation to problems of interest in physics and chemistry. We describe quantum simulation algorithms that have b…
