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…

Using gradient-based algorithms to determine ground state energies on a quantum computer
Tomislav Piskor, Florian G. Eich, Jan-Michael Reiner +4
Variational algorithms are promising candidates to be implemented on near-term quantum computers. The variational quantum eigensolver (VQE) is a prominent example, where a parametr…
