Analog simulation of noisy quantum circuits
Etienne Granet, Kévin Hémery, Henrik Dreyer
It is well-known that simulating quantum circuits with low but non-zero hardware noise is more difficult than without noise. It requires either to perform density matrix simulation…
Experimental Demonstration of Break-Even for the Compact Fermionic Encoding
Ramil Nigmatullin, Kevin Hemery, Khaldoon Ghanem +8
The utility of solving the Fermi-Hubbard model has been estimated in the billions of dollars. Digital quantum computers can in principle address this task, but have so far been lim…
Dilution of error in digital Hamiltonian simulation
Etienne Granet, Henrik Dreyer
We provide analytic, numerical and experimental evidence that the amount of noise in digital quantum simulation of local observables can be independent of system size in a number o…
Practicality of quantum adiabatic algorithm for chemistry applications
Etienne Granet, Khaldoon Ghanem, Henrik Dreyer
Despite its simplicity and strong theoretical guarantees, adiabatic state preparation has received considerably less interest than variational approaches for the preparation of low…
Benchmarking a heuristic Floquet adiabatic algorithm for the Max-Cut problem
Etienne Granet, Henrik Dreyer
According to the adiabatic theorem of quantum mechanics, a system initially in the ground state of a Hamiltonian remains in the ground state if one slowly changes the Hamiltonian.…
A noise-limiting quantum algorithm using mid-circuit measurements for dynamical correlations at infinite temperature
Etienne Granet, Henrik Dreyer
It is generally considered that the signal output by a quantum circuit is attenuated exponentially fast in the number of gates. This letter explores how algorithms using mid-circui…
