PEPR NISQ2LSQ

  • Description: The project aims to significantly accelerate R&D in the theory and design of efficient error-correcting codes in hardware, focusing on bosonic codes and LDPC codes for superconducting and photonic circuits. It aims at demonstrating a fault-tolerant prototype quantum processor based on cat-qubits and to prepare for rapid scaling towards LSQ by the end of the project. In the photonics field, the aim is to define measurement-based computing architectures based on these codes and to experimentally demonstrate the necessary elements for their construction. In the LDPC code field, the focus is on developing essentially optimal codes in terms of encoding rate and error correction, efficient decoding algorithms, and fault-tolerant logical operations specific to LDPC codes.

  • Our contribution: Efficient error characterization, algorithm design.

Quantum Internet Alliance (QIA)

  • Description: QIA’s mission is to develop a full-stack prototype network for a global Quantum Internet made in Europe, while driving innovation in the European Quantum Internet ecosystem. Their specific goals are to establish an innovative platform for Quantum Internet development and advance Quantum Internet technology through the integration of all sub-systems into a prototype network. Their ultimate objective is to build two metropolitan scale networks containing quantum processors connected by a long-distance fiber backbone using quantum repeaters to demonstrate inter-networking capability and pave the way towards a true Quantum Internet.

  • Our contribution: Co-design of client’s hardware and protocols for secure delegated quantum computation.

Efficient Verification of Quantum computing architectures with Bosons (VeriQuB)

  • Description: Quantum devices offer great promise for computation, cryptography, communication, and sensing. Alternative approaches to quantum information processing in which bosonic modes are the carriers of information have attracted increasing attention, because they offer a hardware-efficient path to fault-tolerance and scalability thanks to their inherently large Hilbert space. However, this poses the problem of providing rigorous guarantees of the correct functioning of these promising bosonic architectures, a task known as quantum verification. To date, this verification is performed by general-purpose tomographic techniques, which rapidly become intractable for large quantum systems. Thus, other methods are needed as quantum devices are scaled up to achieve real-world advantages. VeriQuB aims to develop a new approach to the efficient verification of quantum computing architectures with bosons, using continuous-variable measurements.

  • Our contribution: Verification protocol design, bosonic resource theory, complexity theory.

Digital methods in analog quantum simulation (DigiAnaQsim)

  • Description: Quantum materials and molecular systems are governed by strongly correlated particles that can overwhelm classical computation. Analog quantum simulators based on ultracold atoms already access important regimes, but their native models, measurements, and precision remain limited. DigiAnaQsim addresses this gap by importing selected digital quantum-computation techniques into analog cold-atom platforms.

  • Our contribution: Digital-analog protocol design, quantum error mitigation
