The effects of shot noise on the quantum computation of NMR spectra
Sebastian Walch, Keith R. Fratus, Jan-Michael Reiner +1
Recent advances in the field of quantum computing hardware motivate the search for applications which demonstrate so-called quantum advantage. One promising use case that has been…
Can a Quantum Computer Simulate Nuclear Magnetic Resonance Spectra Better than a Classical One?
Keith R. Fratus, Nicklas Enenkel, Sebastian Zanker +3
The simulation of the spectra measured in nuclear magnetic resonance (NMR) spectroscopy experiments is a computationally non-trivial problem which, due to its natural interpretatio…
The Discrete Noise Approximation in Quantum Circuits
Keith R. Fratus, Juha Leppäkangas, Michael Marthaler +1
When modeling the effects of noise on quantum circuits, one often makes the assumption that these effects can be accounted for by individual decoherence events following an otherwi…
A quantum algorithm for solving open system dynamics on quantum computers using noise
Juha Leppäkangas, Nicolas Vogt, Keith R. Fratus +6
In this paper we present a quantum algorithm that uses noise as a resource. The goal of our quantum algorithm is the calculation of operator averages of an open quantum system evol…
Describing Trotterized Time Evolutions on Noisy Quantum Computers via Static Effective Lindbladians
Keith R. Fratus, Kirsten Bark, Nicolas Vogt +4
We consider the extent to which a Trotterized time evolution implemented on a quantum computer is altered by the presence of decoherence. Given a specific set of assumptions regard…
