Exponential quantum speedups for near-term molecular electronic structure methods
Oskar Leimkuhler, K. Birgitta Whaley
We prove classical simulation hardness, under the generalized conjecture, for quantum circuit families with applications in near-term chemical ground st…
Efficient state preparation for the quantum simulation of molecules in first quantization
William J. Huggins, Oskar Leimkuhler, Torin F. Stetina +1
The quantum simulation of real molecules and materials is one of the most highly anticipated applications of quantum computing. Algorithms for simulating electronic structure using…
A quantum eigenvalue solver based on tensor networks
Oskar Leimkuhler, K. Birgitta Whaley
Electronic ground states are of central importance in chemical simulations, but have remained beyond the reach of efficient classical algorithms except in cases of weak electron co…
Say NO to Optimization: A Non-Orthogonal Quantum Eigensolver
Unpil Baek, Diptarka Hait, James Shee +5
A balanced description of both static and dynamic correlations in electronic systems with nearly degenerate low-lying states presents a challenge for multi-configurational methods…
