The project is to develop, exploit and analyze high-precision analog quantum simulators for the experimental exploration and theoretical understanding of a wide range of strongly-correlated electron phenomena and quantum criticality. We plan to develop devices that will provide experimental testbeds
Optically-addressable spin qubits in silicon 28 – OCTOPUS
The OCTOPUS project aims at developing all the building blocks of an efficient spin-photon interface operating at telecom wavelengths in an isotopically-purified silicon 28 wafers, by investigating the magneto-optical properties of an isovalent carbon-related impurity, the so-called G-center. The OC
An Algorithmic Theory of Communication – ACOM
In the road towards quantum technologies that can achieve a quantum advantage, a major bottleneck is the large overhead needed to correct for errors caused by unwanted noise. Despite important research activity and great progress in designing better error correcting codes, the fundamental limits of
Integrated quantum optics using Site-controlled Quantum Dots and molecules – I-SQUAD
Quantum logic operations require manipulation of qubits using both one and two-qubit gates, the latter based on coherent interaction between pairs of qubits. Semiconductor Quantum Dots (QDs) are appealing solid state qubits and their ease of incorporation into conventional semiconductor devices make
High-accuracy model reduction for open quantum systems – HAMROQS
Three objectives: 1. reducing the dimension of systems by eliminating degrees of freedom which converge fast to their steady state value, while keeping a high accuracy in the memory effects induced by this fast convergence. Using these reduced models to get insight on phenomena, design guidelines.
Simulating the Bose Hubbard Model in Superconducting Circuits – BOCA
The main goal of this project is to demonstrate the potential of circuit QED to simulate the Bose-Hubbard (BH) model, which is the canonical model for interacting bosons on a lattice.The BH model has found applications in various fields of condensed matter physics including superconducting thin-film

Since the XIXth century, classical thermodynamics has developed the conceptual and practical tools to harness thermal noise, turning it into a resource. Heat engines efficiently convert heat produced by thermal baths into useful and possibly storable work, by engineering the transformations of worki
Modeling and Assessment of Qubits on Silicon – MAQSi
Quantum information technologies could lead to breakthroughs in computing/simulation and cryptography. France develops an original platform for quantum information, based on the "Silicon on Insulator" (SOI) technology. Yet many aspects of the physics of silicon quantum bits (qubits) remain poorly un
Quantum Information Processing with Hybrid Superconducting Circuits – QIPHSC
Traditional superconducting qubits are based on tunnel Josephson junctions and rely on macroscopic degrees of freedom, namely the superconducting phase difference and the charge difference across the junction. They are therefore intrinsically bosonic by nature. Electronic spin qubits are based on el
