Variational matrix product states for combinatorial optimization
Guillermo Preisser, Conor Mc Keever, Michael Lubasch
To compute approximate solutions for combinatorial optimization problems, we describe variational methods based on the product state (PS) and matrix product state (MPS) ansätze. We…
Quantum circuits for partial differential equations in Fourier space
Michael Lubasch, Yuta Kikuchi, Lewis Wright +1
For the solution of partial differential equations (PDEs), we show that the quantum Fourier transform (QFT) can enable the design of quantum circuits that are particularly simple,…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Filter-enhanced adiabatic quantum computing on a digital quantum processor
Erenay Karacan, Conor Mc Keever, Michael Foss-Feig +2
Eigenstate filters underpin near-optimal quantum algorithms for ground state preparation. Their realization on current quantum computers, however, poses a challenge as the filters…
