Volumetric Benchmarking of Quantum Computing Noise Models
Tom Weber, Kerstin Borras, Karl Jansen +2
The main challenge of quantum computing on its way to scalability is the erroneous behaviour of current devices. Understanding and predicting their impact on computations is essent…

A measurement-based variational quantum eigensolver
Ryan R. Ferguson, Luca Dellantonio, Karl Jansen +3
Variational quantum eigensolvers (VQEs) combine classical optimization with efficient cost function evaluations on quantum computers. We propose a new approach to VQEs using the pr…

Zeta-regularized vacuum expectation values
Tobias Hartung, Karl Jansen
It has recently been shown that vacuum expectation values and Feynman path integrals can be regularized using Fourier integral operator -function, yet the physical meaning of th…
