I did my Ph. D. at Universidad de Murcia (Spain) working on low-temperature transport in semiconductors and optical lattices. After that, I first moved to LPTHE (France) and then to Rutgers Uiversity (US) to work on topics related to Many-Body Localization and superconducting circuits. I came back to Spain, to Quinfog group, thanks to the “Juan de la Cierva” National post-doc program. Currently, I work on the Comfuturo project “Ordenador adiabático cuántico: rendimiento en problemas Np” given by the Fundación General del CSIC .
Scientific interests
I like topics as Many-Body Localization, low temperature transport in disordered systems, quantum chaos or superconducting circuits. I find very exciting the field of quantum technologies. It is a fast developing area with people coming from many different backgrounds, which still find their way to understand each others.
One of my objectives is to describe a glassy dynamics using the laws of quantum mechanics. Although this is a fundamental problem, a better understanding of glassy quantum systems could help us to find the efficiency of quantum computers, specially quatum annealers.
We have recently proposed an improvement in the hardware of quantum annealers so to reduce substantially their error rate. Error correction usually employs logical qubits, which are made of several physical qubits, so that the excess of entropy due to an error does not affect the encoded information. Similarly, our proposal accounts to use the degrees of freedom of the qubit-qubit couplers. Those couplers are already presented in many of the modern quantum computers hardwares to allow flexible and long-range qubit-qubit couplings. We have shown that it is possible to tune those couplers so that the excess of entropy of a local error is absorbed by couplers, thus correcting the error.
