Will Zeng from Rigetti visits us

We have recently received a distinguished visitor at QUANTIC, Will Zeng who is one of the software leaders in the new startup Rigetti Computing, which aim at building a quantum computer. The company recently opened up their 19-qubit small quantum computer for remote user access through their cloud environment. The researchers at QUANTIC are already testing this new technological wonder.

Will led the development of the software and theory teams at Rigetti Computing, including the Forest quantum programming environment.  He started working with superconducting qubits in Michel Devoret and Andreas Wallraff’s labs before his PhD at Oxford on the mathematical structure of quantum algorithms.

It was nice having you around Will!

We are on Twitter!

Our group has launched a twitter account, @QUANTIC_BSC

Our twitter profile. It’s a Q, using the loop of a flux qubit.

We will be generating content as news from our group and from the world on quantum computation, simulation and in general quantum technologies unfold.

Workshop Bilbao Quantum Computation and Simulation

Last week one of the most important events this year on Quantum Computation and Simulation took place in Bilbao. The workshop gathered some of the experts in the field from all over the world, both in the experimental as well as the theory areas. As a novelty, a round table including representatives of the quantum technology industry was chaired by Víctor Canivell, president of the Quantum World Association. Prof. J. I. Latorre participated in the table as a partner of the consultancy Entanglement Partners.

Our group was represented at the workshop as organizers (Pol Forn-Díaz and José Ignacio Latorre) and as presenters. Artur García-Sáez presented his latest work on a non-trivial and potentially useful new quantum algorithm, the adiabatically-assisted variational quantum eigensolver (AAVQE) that caused some sensation. This work is the first project at QUANTIC seeing the light.

Two new TFG students!

Sergi Ramos and Sergi Duaigües have joined QUANTIC to work on their TFG (‘treball de final de grau’, or undergraduate thesis). They will both join Prof. J. I. Latorre’s theory team to work on coherent quantum annealing and variational quantum algorithms, respectively. They will stay until the end of the semester. Welcome to QUANTIC!

New PhD student!

The QUANTIC family is growing. A new PhD student, Carlos Bravo Prieto, joined the team to work on quantum algorithms. Carlos will be based at UB under Prof. J. I. Latorre. He will work closely with the experimental team at BSC to design a first generation of algorithms for real quantum computers. Welcome Carlos!

New paper on Two-photon Quantum Rabi model

A new publication has appeared led by Dr. Pol Forn-Díaz on the theoretical implementation of the two-photon quantum Rabi model. A purely genuine, two-photon interaction is a very intriguing effect, and it is very difficult to find a system in nature that exhibits such phenomenon. In this work, which is a collaboration with the group of Prof. Solano at UPV-EHU in Bilbao, the team found a superconducting circuit which is described by a purely two-photon interaction. The work also investigated the very intriguing phenomenon of a spectral collapse, when the two-photon interaction exceeds a certain critical value and the spectrum of the systems becomes unbounded. The work appeared in Physical Review A. The full reference is Phys. Rev. A 97, 013851 (2018).

This circuit, consisting of a dc-SQUID and a flux qubit, implements the two-photon quantum Rabi model.

 

New group member

MSc. Chris W. Warren joined the QUANTIC group as a ‘Research Engineer’. Chris will join the experimental team to set up the first generation of experiments with superconducting qubits. Chris just finished his Master thesis at the Institute for Quantum Computation (University of Waterloo) under the supervision of Prof. C. M. Wilson.

Welcome Chris!

Pol Forn-Díaz awarded MISTI Seed Fund

Dr. Pol Forn-Díaz has been awarded the MIT International Science and Technology Initiative Seed Fund, together with MIT Professor William D. Oliver and Dr. Simon Gustavsson. The 20,000 USD grant is awarded by the MIT-Spain – “La Caixa” Foundation.

The award will strengthen the already existing collaboration between the BSC and MIT groups in their project to build a superconducting quantum processor.
