    Achieving an advantage over conventional computers to solve problems which are ubiquitous in society.

    Quantum Computation (QC) is arguably the most revolutionary of all new quantum technologies, as it may transform many industrial sectors with a direct impact on society. In the past five years, the field has experienced a huge transformation as it is being adopted and developed by industry after two decades being an almost purely academic endeavor.

    There exist today small-scale prototypes produced by both research groups and large corporations. Those devices are getting powerful enough to provide advantages over conventional computers in specific applications. However, in order to achieve the long-sought “quantum supremacy”, several key developments are still necessary.

    IFAE is fully engaged in this technology since 2019. The particular implementation developed at IFAE, quantum annealing, is one of the most promising avenues by which to achieve an advantage over conventional computers by solving optimization problems which are ubiquitous in society (delivery, traffic, chemistry, etc.).

    The QCT group develops superconducting circuits for applications in quantum computation. By employing Josephson-junction technology, the group engineers superconducting qubits for the implementetion of quantum algorithms. Part of the research is focused on improving the qubit quality by mitigation of environmental noise sources, while at the same time the circuits are used to investigate fundamental physics of quantum optics phenomena.

      Plan Complementario, 2021

      Comunicación Cuántica

      This program is aligned with the key European initiatives in this area, both the Quantum Flagship and the European Quantum Communications Infrastructure (EuroQCI), by creating cutting-edge infrastructures and acting as a motor for the European quantum industry. IFAE participates in the NESQQ subproject, that will aim at improving qubit quality by intensive fabrication efforts, both studying the addition of novel materials as well as by modifications of the qubit device structure. This project will be run in collaboration with IMB-CNM-CSIC via the researcher Dr. Gemma Rius, an active collaborator of the QCT group

        Proyectos I+D Generación de Conocimiento, 2021

        Interacción de la radiación cósmica en cúbits (ICRQ)

        The ICQR project aims to develop superconducting qubits that are resilient against the impact of ionizing radiation, which limit their performance as quantum sensors and hinder the implementation of quantum error correction schemes. This will be achieved by suppressing the generation of spurious quasiparticles in the superconductor through the use of complementary approaches, including operation in a deep underground laboratory, the use of radiopure materials, and on-chip patterns for quasiparticle abatement. Project coordinated by IFAE.

          Avaqus

          H2020-FETOPEN, 2019

          Annealing-based VAriational QUantum processorS (AVaQus)

          AVaQus is a European project funded in the FET-Open 2019 call to develop a quantum processor that demonstrates coherent quantum annealing and its potential to solve real-life optimization problems. Project coordinated by IFAE.

          QUANTERA Logo

          Programa Estatal de I+D+i Orientada a los Retos de la Sociedad, 2019

          Superinductor-based Quantum Technologies with Ultrastrong Couplings (SiUCs)

          SiUCS focus on improving the efficiency of qubit operations involving light-matter interactions. In addition, superinductors are used to engineer a missing device of the superconducting quantum circuit toolbox: the microwave single photon detector.
