We would like to offer support to researchers conducting their work in Ukraine that saw their projects disrupted to continue their work in our group in Barcelona. We can offer logistic support, travel, accommodation and all necessary research facilities at our reach. We are an experimental group but we welcome theoretical researchers as well. We are participating in a global effort of labs supporting Ukranian scientists .
If you know any Ukranian researchers at the Masters, PhD and/or postdoctoral level working on quantum physics, quantum computing, superconductivity, please tell them to contact us.
The Quantum Computing Technologies (QCT) group at the Institute for High Energy Physics (IFAE) offers a one month internship in the context of IFAE’s 7th Summer Internship initiative IFAE’s offcial webpage .
The aim of this one-month stay is to become the first step of University students research career. Participants will have the opportunity to discover the real life of a scientist working side by side with QCT researchers. This programme is valuable complement to your physics education.
The Quantum Computing Technologies (QCT) group at the Institute for High Energy Physics (IFAE) and the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) offer a joint postdoctoral position within the project Nanofabrication-Enhanced Superconducting Qubit Quality (NESQQ), funded by the Spanish Ministry of Science and Innovation.
Project NESQQ aims at the improvement of superconducting qubit quality by combining nanofabrication and noise filtering techniques. The project will look at improving qubit coherence time and parameter reproducibility by reduction of on-chip microscopic flux and charge noise following state-of-the-art nanolithography and processing techniques.
The QCT group has observed the first superconducting flux qubit in the experimental setup at IFAE. This is a milestone for the group. The chip was designed at IFAE and manufactured in Glasgow as part of the AVaQus Collaboration. The group will soon characterize the qubit spectrum and lifetime.
The image shows the unequivocal sign of the presence of a superconducting qubit. The horizontal line is the resonance frequency of the resonator that is used to measure the qubit.
As part of the 2021 BIST Conference and this year’s Setmana de la Ciència, the Barcelona Institute of Science and Technology brought together more than 1400 students from 44 schools across Catalonia to learn about quantum technologies.
Pol Forn-Díaz presented a talk and participated in a discussion panel on the 2021 BIST Conference of Quantum technologies: Present and Future. The topic of the discussion was about the future and implementation of quantum computing, in scope of both local and global industry and research. The 2021 BIST Conference ‘Quantum Technologies: Present and Future’ invites its entire community and its many stakeholders and partners to meet, discuss and present the latest developments in Catalonia in the areas of quantum communication, simulations, computing, sensing, and infrastructures.
As every year, at the end of September, the European Researchers’ Night events help to spread fundamental concepts of research’s world to the most generic public possible. This year, our David López-Núñez gave a talk titled “How do you make a quantum computer?”. Any other information can be find at this link .
Carla Caro Villanova earned the first place in the European Union Contest for Young Scientists (EUCYS) 2021, thanks to her project “Formulation and implementation of a support vector machine on D-Wave’s quantum annealer”, held in Salamanca (Spain) on 19th, September. The contest rewards the best young scientific talent that Europe has to offer. Carla conducted her research project co-supervised by David López-Núñez and already won the first prize of the competition XXXII Certamen Jóvenes Investigadores .
We welcome Ariadna Gómez del Pulgar, from Universitat de Barcelona in our group. Ariadna is doing her Bachelor thesis in superconducting rasonators with granular aluminium, with a particoular stress on fabrication techniques. Welcome aboard!
We present theoretical transmission spectra of a strongly driven, damped, flux qubit coupled to a dissipative resonator in the ultrastrong coupling regime. Such a qubit-oscillator system, described within a dissipative Rabi model, constitutes the building block of superconducting circuit QED platforms. The addition of a strong drive allows one to characterize the system properties and study novel phenomena, leading to a better understanding and control of the qubit-oscillator system. In this work, the calculated transmission of a weak probe field quantifies the response of the qubit, in frequency domain, under the influence of the quantized resonator and of the strong microwave drive.
