A Validation Framework for Quantum Simulation of Spin Dynamics against Inelastic Neutron Scattering and Classical Simulation
Gilles Buchs, Elaine Wong, Anshumitra Baul +15
Quantitative validation of quantum simulations of dynamical spin response remains challenging because experiment, classical simulation, and quantum simulation do not produce the sa…
Benchmarking quantum simulation with neutron-scattering experiments
Yi-Ting Lee, Keerthi Kumaran, Bibek Pokharel +7
Realistic simulation of quantum materials is a central goal of quantum computation. Although quantum processors have advanced rapidly in scale and fidelity, it has remained unclear…
Robust Chiral Edge Dynamics of a Kitaev Honeycomb on a Trapped Ion Processor
Ammar Ali, Joe Gibbs, Keerthi Kumaran +6
Kitaev's honeycomb model is a paradigmatic exactly solvable system hosting a quantum spin liquid with non-Abelian anyons and topologically protected edge modes, offering a platform…
Superdiffusion resilience in Heisenberg Chains with 2D interactions on a quantum processor
Keerthi Kumaran, Manas Sajjan, Bibek Pokharel +7
Observing superdiffusive scaling in the spin transport of the integrable 1D Heisenberg model is one of the key discoveries in non-equilibrium quantum many-body physics. Despite thi…
Transmon qutrit-based simulation of spin-1 AKLT systems
Keerthi Kumaran, Faisal Alam, Norhan Eassa +5
Qutrit-based quantum circuits could help reduce the overall circuit depths, and hence the effect of noise, when the system of interest has a local dimension of three. Accessing sec…
Random Projection using Random Quantum Circuits
Keerthi Kumaran, Manas Sajjan, Sangchul Oh +1
The random sampling task performed by Google's Sycamore processor gave us a glimpse of the "Quantum Supremacy era". This has definitely shed some spotlight on the power of random q…
