Noise Reduction for Universal Hybrid Oscillator-Qubit Quantum Computation
Mohammad Nobakht, Ivan Kassal
Hybrid continuous-variable--discrete-variable (CV--DV) architectures process quantum information in bosonic modes and qubits, but noise limits their performance. To reduce the nois…
Programmable generation of arbitrary continuous-variable anharmonicities and nonlinear couplings
Teerawat Chalermpusitarak, Kai Schwennicke, Ivan Kassal +1
Harmonic oscillators are promising continuous-variable (CV) quantum resources because their infinite-dimensional Hilbert spaces allow for resource-efficient quantum computing and s…
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…
Programmable quantum simulation of anharmonic dynamics
Cameron McGarry, Teerawat Chalermpusitarak, Kai Schwennicke +9
Continuous-variable-discrete-variable (CV-DV) quantum simulators offer a natural route to simulating bosonic dynamics relevant to many branches of physics and chemistry. However, p…
Delocalisation explains efficient transport and charge generation in neat Y6 organic photovoltaics
Daniel Balzer, Paul A. Hume, Geoffrey R. Weal +2
Non-fullerene acceptors (NFA), such as Y6, have significantly improved the efficiency of organic photovoltaic devices (OPVs). However, the fundamental processes behind the high eff…
Using bosons to improve resource efficiency of quantum simulation of vibronic molecular dynamics
Henry L. Nourse, Vanessa C. Olaya-Agudelo, Ivan Kassal
Simulating chemical dynamics is computationally challenging, especially for nonadiabatic dynamics, where numerically exact classical simulations scale exponentially with system siz…
