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…
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…
