Nearly Optimal Amplitude Estimation at any Depth
Jona Erle, Bálint Koczor
We develop a class of amplitude estimation algorithms with tunable circuit depth and circuit repetitions , requiring neither ancilla qubits nor controlled Grover operations.…

A Shadow Enhanced Greedy Quantum Eigensolver
Jona Erle, Balint Koczor
While ground-state preparation is expected to be a primary application of quantum computers, it is also an essential subroutine for many fault-tolerant algorithms. In early fault-t…

The non-equilibrium solvent response force: What happens if you push a Brownian particle
Fabian Koch, Jona Erle, Tanja Schilling
In this letter we discuss how to add forces to the Langevin equation. We derive the exact generalized Langevin equation for the dynamics of one particle subject to an external forc…
