Spectral amplification for ground-state energy estimation of electronic structure in first quantization
Alicja Dutkiewicz, Alec F. White, Guang Hao Low +6
We demonstrate an asymptotic gate complexity improvement in first-quantized ground-state energy estimation of electronic structure Hamiltonians in a plane wave basis by employing t…
Constant Factor Analysis of Optimal Quantum Linear Solvers in Practice
Pedro C. S. Costa, Alexander M. Dalzell, Dong An +1
Optimal quantum linear equation solvers provide complexity , where is the condition number and is the allowable error. The optimal solver using a discrete ad…
End-to-End Simulation of Chemical Dynamics on a Quantum Computer
Elliot C. Eklund, Arkin Tikku, Patrick Sinnott +4
Simulations of chemical dynamics are a powerful means for understanding chemistry. However, classical computers struggle to simulate many chemical processes, especially non-adiabat…
Quantum simulation of electronic structure via quantum fast multipole method
Dominic W. Berry, Kianna Wan, Andrew D. Baczewski +3
Here we describe an approach for simulating electronic structure on quantum computers with significantly lower asymptotic complexity than prior work. The approach uses a real-space…
Large time-step discretisation of adiabatic quantum dynamics
Dong An, Pedro C. S. Costa, Dominic W. Berry
Adiabatic quantum computing is a general framework for preparing eigenstates of Hamiltonians on quantum devices. However, its digital implementation requires an efficient Hamiltoni…
Quantum algorithm for linear matrix equations
Rolando D. Somma, Guang Hao Low, Dominic W. Berry +1
We describe an efficient quantum algorithm for solving the linear matrix equation AX+XB=C, where A, B, and C are given complex matrices and X is unknown. This is known as the Sylve…
