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…

Post-processing noisy quantum computations utilizing N-representability constraints
Tomislav Piskor, Florian G. Eich, Michael Marthaler +2
We propose and analyze a method for improving quantum chemical energy calculations on a quantum computer impaired by decoherence and shot noise. The error mitigation approach relie…
