Closest Accessible Symmetry reduction: a tool for Hamiltonian interpolation analysis
Ana Palacios, Artur Garcia-Saez, Arnau Riera +1
We introduce a framework for analysing the spectrum of Hamiltonian interpolations without heavily relying on discretising the interpolation parameter. The method is based on the co…
Quantum entanglement patterns in the structure of atomic nuclei within the nuclear shell model
A. Pérez-Obiol, S. Masot-Llima, A. M. Romero +4
Quantum entanglement offers a unique perspective into the underlying structure of strongly-correlated systems such as atomic nuclei. In this paper, we use quantum information tools…
Bounding first-order quantum phase transitions in adiabatic quantum computing
Matthias Werner, Artur García-Sáez, Marta P. Estarellas
In the context of adiabatic quantum computation (AQC), it has been argued that first-order quantum phase transitions (QPTs) due to localisation phenomena cause AQC to fail by expon…
One qubit as a Universal Approximant
Adrián Pérez-Salinas, David López-Núñez, Artur García-Sáez +2
A single-qubit circuit can approximate any bounded complex function stored in the degrees of freedom defining its quantum gates. The single-qubit approximant presented in this work…
