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…
Classical Estimation of the Free Energy and Quantum Gibbs Sampling from the Markov Entropy Decomposition
Samuel O. Scalet, Angela Capel, Anirban N. Chowdhury +4
We revisit the Markov Entropy Decomposition, a classical convex relaxation algorithm introduced by Poulin and Hastings to approximate the free energy in quantum spin lattices. We i…
Roadmap for Molecular Benchmarks in Nonadiabatic Dynamics
Léon E. Cigrang, Basile F. E. Curchod, Rebecca A. Ingle +42
Simulating the coupled electronic and nuclear response of a molecule to light excitation requires the application of nonadiabatic molecular dynamics. However, when faced with a spe…
Experimental demonstration of the advantage of adaptive quantum circuits
Michael Foss-Feig, Arkin Tikku, Tsung-Cheng Lu +16
Adaptive quantum circuits employ unitary gates assisted by mid-circuit measurement, classical computation on the measurement outcome, and the conditional application of future unit…
Circuit depth versus energy in topologically ordered systems
Arkin Tikku, Isaac H. Kim
We prove a nontrivial circuit-depth lower bound for preparing a low-energy state of a locally interacting quantum many-body system in two dimensions, assuming the circuit is geomet…
Non-additivity in classical-quantum wiretap channels
Arkin Tikku, Mario Berta, Joseph M. Renes
Due to Csiszar and Koerner, the private capacity of classical wiretap channels has a single-letter characterization in terms of the private information. For quantum wiretap channel…
Variational Quantum State Diagonalization
Ryan LaRose, Arkin Tikku, Étude O'Neel-Judy +2
Variational hybrid quantum-classical algorithms are promising candidates for near-term implementation on quantum computers. In these algorithms, a quantum computer evaluates the co…
