Warm-Starting the VQE with Approximate Complex Amplitude Encoding
Felix Truger, Johanna Barzen, Frank Leymann +1
The Variational Quantum Eigensolver (VQE) is a Variational Quantum Algorithm (VQA) to determine the ground state of quantum-mechanical systems. As a VQA, it makes use of a classica…
Comparing Quantum Service Offerings
Julian Obst, Johanna Barzen, Martin Beisel +3
With the emergence of quantum computing, a growing number of quantum devices is accessible via cloud offerings. However, due to the rapid development of the field, these quantum-sp…
Investigating the effect of circuit cutting in QAOA for the MaxCut problem on NISQ devices
Marvin Bechtold, Johanna Barzen, Frank Leymann +4
Noisy Intermediate-Scale Quantum (NISQ) devices are restricted by their limited number of qubits and their short decoherence times. An approach addressing these problems is quantum…
