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 phas…
Programmable digital quantum simulation of 2D Fermi-Hubbard dynamics using 72 superconducting qubits
Faisal Alam, Jan Lukas Bosse, Ieva ÄepaitÄ +32
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 ÄepaitÄ +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…
