Optimal Coherent Quantum Phase Estimation via Tapering
Dhrumil Patel, Shi Jie Samuel Tan, Yigit Subasi +1
Due to its significance as a subroutine, in this work, we consider the coherent version of the quantum phase estimation problem, where given an arbitrary input state and black-box…
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…
