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…
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…
The Grand Challenge of Quantum Applications
Ryan Babbush, Robbie King, Sergio Boixo +6
This perspective outlines promising pathways and critical obstacles on the road to developing useful quantum computing applications, drawing on insights from the Google Quantum AI…
The FLuid Allocation of Surface code Qubits (FLASQ) cost model for early fault-tolerant quantum algorithms
William J. Huggins, Tanuj Khattar, Amanda Xu +6
Holistic resource estimates are essential for guiding the development of fault-tolerant quantum algorithms and the computers they will run on. This is particularly true when we foc…
Block encoding with low gate count for second-quantized Hamiltonians
Diyi Liu, Shuchen Zhu, Guang Hao Low +2
Efficient block encoding of many-body Hamiltonians is a central requirement for quantum algorithms in scientific computing, particularly in the early fault-tolerant era. In this wo…
Optimal quantum simulation of linear non-unitary dynamics
Guang Hao Low, Rolando D. Somma
We present a quantum algorithm for simulating the time evolution generated by any bounded, time-dependent operator with non-positive logarithmic norm, thereby serving as a nat…
