PEPR

Through several projects within the Quantum Priority Research Program and Equipment (PEPR), Université Paris Cité actively contributes to structuring French research in quantum technologies, from computing to communication, including architecture and simulation.

A strategic involvement in PEPR Quantum

Université Paris Cité is engaged in multiple PEPR Quantum projects, a national program supporting the National Acceleration Strategy for Quantum Technologies. These projects aim to develop the scientific, technological, and instrumental building blocks that will shape future generations of quantum computers and networks.

By actively participating in these PEPR projects, Université Paris Cité asserts its role as a driver of French quantum innovation, at the intersection of fundamental research, technological development, and industrial applications.

Exploring the foundations of quantum computing (EPIQ project)

The EPIQ project develops algorithmic techniques for both noisy intermediate-scale quantum (NISQ) machines and fault-tolerant systems.

Its focus areas include:

• Better understanding the advantages and limits of quantum computing through research in complexity and algorithms

• Designing high-level programming languages and comparing different computational models to optimize programs

• Developing simulation tools to anticipate the real-world performance of algorithms on noisy machines

An open infrastructure for research and industry (HQI project)

The HQI initiative provides academic and industrial scientists, in France and across Europe, with free access to evaluate the potential of quantum computing on a public infrastructure. The project also encourages international collaborations to support open and shared research.

Towards secure quantum communications (QCOMMTESTBED project)

The QCOMMTESTBED project establishes a national testbed for quantum communication, with two major infrastructures in Paris and Nice. Its objectives are to:

• Develop innovative and operational quantum communication devices

• Design and test communication protocols

• Assess the security of exchanges under real-world conditions

Designing the quantum error-correcting codes of the future (NISQ2LSQ project)

The NISQ2LSQ project accelerates research on error-correcting codes adapted to quantum architectures. It explores two promising approaches—bosonic codes and LDPC (Low-Density Parity-Check) codes—applied to two types of platforms: superconducting circuits and photonic circuits.

A technological breakthrough: flying qubits (eQubitFly project)

With eQubitFly, researchers are developing a new quantum architecture based on flying electronic qubits. This innovative approach aims to:

• Generate single-electron excitations on demand, on picosecond timescales

• Detect these flying electrons individually, opening the way to faster and interconnected quantum devices

Connecting microwaves and light (QUMOMI project)

The QUMOMI project is designing a quantum interface between microwaves and infrared optics, a key milestone for the interoperability of quantum architectures. Its goal is to enable optical entanglement of distant microwave qubits, facilitating the scaling and connectivity of future quantum systems.
