Efficient quantum computation of molecular forces and other energy gradients
Thomas E. O'Brien, Michael Streif, Nicholas C. Rubin +12
While most work on the quantum simulation of chemistry has focused on computing energy surfaces, a similarly important application requiring subtly different algorithms is the comp…
Simulations of Quantum Circuits with Approximate Noise using qsim and Cirq
Sergei V. Isakov, Dvir Kafri, Orion Martin +15
We introduce multinode quantum trajectory simulations with qsim, an open source high performance simulator of quantum circuits. qsim can be used as a backend of Cirq, a Python soft…
Compressing Many-Body Fermion Operators Under Unitary Constraints
Nicholas C. Rubin, Joonho Lee, Ryan Babbush
The most efficient known quantum circuits for preparing unitary coupled cluster states and applying Trotter steps of the arbitrary basis electronic structure Hamiltonian involve in…
Observation of Time-Crystalline Eigenstate Order on a Quantum Processor
Xiao Mi, Matteo Ippoliti, Chris Quintana +102
Quantum many-body systems display rich phase structure in their low-temperature equilibrium states. However, much of nature is not in thermal equilibrium. Remarkably, it was recent…
pq: A tool for prototyping many-body methods for quantum chemistry
Nicholas C. Rubin, A. Eugene DePrince
pq is a C++ accelerated Python library designed to generate equations for many-body quantum chemistry methods and to realize proof-of-concept implementations of these equ…
Unbiasing Fermionic Quantum Monte Carlo with a Quantum Computer
William J. Huggins, Bryan A. O'Gorman, Nicholas C. Rubin +3
Many-electron problems pose some of the greatest challenges in computational science, with important applications across many fields of modern science. Fermionic quantum Monte Carl…
What the foundations of quantum computer science teach us about chemistry
Jarrod R. McClean, Nicholas C. Rubin, Joonho Lee +5
With the rapid development of quantum technology, one of the leading applications is the simulation of chemistry. Interestingly, even before full scale quantum computers are availa…
Fault-Tolerant Quantum Simulations of Chemistry in First Quantization
Yuan Su, Dominic W. Berry, Nathan Wiebe +2
Quantum simulations of chemistry in first quantization offer important advantages over approaches in second quantization including faster convergence to the continuum limit and the…

K. J. Satzinger, Y. Liu, A. Smith +95
The discovery of topological order has revolutionized the understanding of quantum matter in modern physics and provided the theoretical foundation for many quantum error correctin…
The Fermionic Quantum Emulator
Nicholas C. Rubin, Klaas Gunst, Alec White +5
The fermionic quantum emulator (FQE) is a collection of protocols for emulating quantum dynamics of fermions efficiently taking advantage of common symmetries present in chemical,…
Exponential suppression of bit or phase flip errors with repetitive error correction
Zijun Chen, Kevin J. Satzinger, Juan Atalaya +88
Realizing the potential of quantum computing will require achieving sufficiently low logical error rates. Many applications call for error rates in the regime, but state…
Information Scrambling in Computationally Complex Quantum Circuits
Xiao Mi, Pedram Roushan, Chris Quintana +90
Interaction in quantum systems can spread initially localized quantum information into the many degrees of freedom of the entire system. Understanding this process, known as quantu…
