On Performance and Limitations of Quantum Wave Packet Dynamics Simulated using NISQ Hardware
Tamila Kuanysheva, Jonathan Andrade-Plascencia, Jayakrushna Sahoo +2
We investigate one-dimensional quantum wave-packet dynamics using a grid-based encoding of the wave function onto qubit registers. Time evolution is implemented using a split opera…
Long-range states in collisions of ultracold molecules
James F. E. Croft, Brian K. Kendrick, Jeremy M. Hutson
We use coupled-channel calculations to explore the nature of near-threshold bound states in a simplified model of Rb+KRb. This is a prototype for systems with very strong coupling…
Quantum Simulation of Molecular Dynamics Processes -- A Benchmark Study Using Classical Simulator and Present-Day Quantum Hardware
Tamila Kuanysheva, Brian Kendrick, Lukasz Cincio +1
We explore how the fundamental problems in quantum molecular dynamics can be modelled using classical simulators (emulators) of quantum computers and the actual quantum hardware av…
Electronic structure with direct diagonalization on a D-Wave quantum annealer
Alexander Teplukhin, Brian K. Kendrick, Sergei Tretiak +1
Quantum chemistry is regarded to be one of the first disciplines that will be revolutionized by quantum computing. Although universal quantum computers of practical scale may be ye…
Long-lived complexes and signatures of chaos in ultracold K2+Rb collisions
J. F. E. Croft, N. Balakrishnan, B. K. Kendrick
Lifetimes of complexes formed during ultracold collisions are of current experimental interest as a possible cause of trap loss in ultracold gases of alkali-dimers. Microsecond lif…
Symmetry and the Geometric Phase in Ultracold Hydrogen-Exchange Reactions
J. F. E. Croft, J. Hazra, N. Balakrishnan +1
Quantum reactive scattering calculations are reported for the ultracold hydrogen-exchange reaction and its non-reactive atom-exchange isotopic counterparts, proceeding from excited…
