Quantum Chemistry in the Age of Quantum Computing
Yudong Cao, Jonathan Romero, Jonathan P. Olson +10
Practical challenges in simulating quantum systems on classical computers have been widely recognized in the quantum physics and quantum chemistry communities over the past century…
QAOA for Max-Cut requires hundreds of qubits for quantum speed-up
G. G. Guerreschi, A. Y. Matsuura
Computational quantum technologies are entering a new phase in which noisy intermediate-scale quantum computers are available, but are still too small to benefit from active error…
Quantum algorithm for calculating molecular vibronic spectra
Nicolas P. D. Sawaya, Joonsuk Huh
We present a quantum algorithm for calculating the vibronic spectrum of a molecule, a useful but classically hard problem in chemistry. We show several advantages over previous qua…
Impact of qubit connectivity on quantum algorithm performance
Adam Holmes, Sonika Johri, Gian Giacomo Guerreschi +2
Quantum computing hardware is undergoing rapid development from proof-of-principle devices to scalable machines that could eventually challenge classical supercomputers on specific…
Repeat-Until-Success circuits with fixed-point oblivious amplitude amplification
Gian Giacomo Guerreschi
Certain quantum operations can be built more efficiently through a procedure known as Repeat-Until-Success. Differently from other non-deterministic quantum operations, this proced…
Rent's rule and extensibility in quantum computing
David P. Franke, James S. Clarke, Lieven M. K. Vandersypen +1
Quantum computing is on the verge of a transition from fundamental research to practical applications. Yet, to make the step to large-scale quantum computation, an extensible qubit…
