Quantum Phaselift
Dhrumil Patel, Laura Clinton, Steven T. Flammia +1
Estimating quantum time-series such as the Loschmidt amplitude is central to spectroscopy, Hamiltonian analysis, and many phase-…
Programmable digital quantum simulation of 2D Fermi-Hubbard dynamics using 72 superconducting qubits
Faisal Alam, Jan Lukas Bosse, Ieva Čepaitė +41
Simulating the time-dynamics of quantum many-body systems was the original use of quantum computers proposed by Feynman, motivated by the critical role of quantum interactions betw…
Fermionic dynamics on a trapped-ion quantum computer beyond exact classical simulation
Faisal Alam, Jan Lukas Bosse, Ieva Čepaitė +37
Simulation of the time-dynamics of fermionic many-body systems has long been predicted to be one of the key applications of quantum computers. Such simulations -- for which classic…
Quantum Phase Estimation without Controlled Unitaries
Laura Clinton, Toby S. Cubitt, Raul Garcia-Patron +3
In this work we demonstrate the use of adapted classical phase retrieval algorithms to perform control-free quantum phase estimation. We eliminate the costly controlled time evolut…
Towards near-term quantum simulation of materials
Laura Clinton, Toby Cubitt, Brian Flynn +6
Simulation of materials is one of the most promising applications of quantum computers. On near-term hardware the crucial constraint on these simulations is circuit depth. Many qua…
Phase Estimation of Local Hamiltonians on NISQ Hardware
Laura Clinton, Johannes Bausch, Joel Klassen +1
In this work we investigate a binned version of Quantum Phase Estimation (QPE) set out by [Somma 2019] and known as the Quantum Eigenvalue Estimation Problem (QEEP). Specifically,…
Hamiltonian Simulation Algorithms for Near-Term Quantum Hardware
Laura Clinton, Johannes Bausch, Toby Cubitt
The quantum circuit model is the de-facto way of designing quantum algorithms. Yet any level of abstraction away from the underlying hardware incurs overhead. In the era of near-te…
