The Quantum Approximate Optimization Algorithm performance with low entanglement and high circuit depth
Rishi Sreedhar, Pontus Vikstål, Marika Svensson +3
Variational quantum algorithms constitute one of the most widespread methods for using current noisy quantum computers. However, it is unknown if these heuristic algorithms provide…
Quantifying Qubit Magic Resource with Gottesman-Kitaev-Preskill Encoding
Oliver Hahn, Alessandro Ferraro, Lina Hultquist +2
Quantum resource theories are a powerful framework to characterize and quantify relevant quantum phenomena and identify processes that optimize their use for different tasks. Here,…
Qubit Motion as a Microscopic Model for the Dynamical Casimir Effect
Andrés Agustí, Laura García-Álvarez, Enrique Solano +1
The generation of photons from the vacuum by means of the movement of a mirror is known as the dynamical Casimir effect (DCE). In general, this phenomenon is effectively described…
Benchmarking the Variational Quantum Eigensolver through Simulation of the Ground State Energy of Prebiotic Molecules on High-Performance Computers
P. Lolur, M. Rahm, M. Skogh +2
We use the Variational Quantum Eigensolver (VQE) as implemented in the Qiskit software package to compute the ground state energy of small molecules derived from water, HO, and…
Efficient simulatability of continuous-variable circuits with large Wigner negativity
Laura García-Álvarez, Cameron Calcluth, Alessandro Ferraro +1
Discriminating between quantum computing architectures that can provide quantum advantage from those that cannot is of crucial importance. From the fundamental point of view, estab…
From the Bloch sphere to phase space representations with the Gottesman-Kitaev-Preskill encoding
L. García-Álvarez, A. Ferraro, G. Ferrini
In this work, we study the Wigner phase-space representation of qubit states encoded in continuous variables (CV) by using the Gottesman-Kitaev-Preskill (GKP) mapping. We explore a…
