Fast emulation of fermionic circuits with matrix product states
Justin Provazza, Klaas Gunst, Huanchen Zhai +4
We describe a matrix product state (MPS) extension for the Fermionic Quantum Emulator (FQE) software library. We discuss the theory behind symmetry adapted matrix product states fo…
Quantum Simulation of Realistic Materials in First Quantization Using Non-local Pseudopotentials
Dominic W. Berry, Nicholas C. Rubin, Ahmed O. Elnabawy +5
This paper improves and demonstrates the usefulness of the first quantized plane-wave algorithms for the quantum simulation of electronic structure, developed by Babbush et al. and…
Quantum computation of stopping power for inertial fusion target design
Nicholas C. Rubin, Dominic W. Berry, Alina Kononov +7
Stopping power is the rate at which a material absorbs the kinetic energy of a charged particle passing through it -- one of many properties needed over a wide range of thermodynam…
Zero and Finite Temperature Quantum Simulations Powered by Quantum Magic
Andi Gu, Hong-Ye Hu, Di Luo +3
We introduce a quantum information theory-inspired method to improve the characterization of many-body Hamiltonians on near-term quantum devices. We design a new class of similarit…
Dynamics of magnetization at infinite temperature in a Heisenberg spin chain
Eliott Rosenberg, Trond Andersen, Rhine Samajdar +178
Understanding universal aspects of quantum dynamics is an unresolved problem in statistical mechanics. In particular, the spin dynamics of the 1D Heisenberg model were conjectured…
Stable Quantum-Correlated Many Body States through Engineered Dissipation
X. Mi, A. A. Michailidis, S. Shabani +164
Engineered dissipative reservoirs have the potential to steer many-body quantum systems toward correlated steady states useful for quantum simulation of high-temperature supercondu…
Phase transition in Random Circuit Sampling
A. Morvan, B. Villalonga, X. Mi +182
Undesired coupling to the surrounding environment destroys long-range correlations on quantum processors and hinders the coherent evolution in the nominally available computational…
Measurement-induced entanglement and teleportation on a noisy quantum processor
Jesse C. Hoke, Matteo Ippoliti, Eliott Rosenberg +160
Measurement has a special role in quantum theory: by collapsing the wavefunction it can enable phenomena such as teleportation and thereby alter the "arrow of time" that constrains…
Fault-tolerant quantum simulation of materials using Bloch orbitals
Nicholas C. Rubin, Dominic W. Berry, Fionn D. Malone +8
The simulation of chemistry is among the most promising applications of quantum computing. However, most prior work exploring algorithms for block-encoding, time-evolving, and samp…
Drug design on quantum computers
Raffaele Santagati, Alan Aspuru-Guzik, Ryan Babbush +12
Quantum computers promise to impact industrial applications, for which quantum chemical calculations are required, by virtue of their high accuracy. This perspective explores the c…
Expanding the reach of quantum optimization with fermionic embeddings
Andrew Zhao, Nicholas C. Rubin
Quadratic programming over orthogonal matrices encompasses a broad class of hard optimization problems that do not have an efficient quantum representation. Such problems are insta…
