Experiment

We are developing experiments to create large entangled states of neutral atoms using quantum-coherent control, and investigate new possibilities for high-fidelity quantum control and measurement. This builds upon our prior, foundational work with entangling interactions using ultra-cold Rydberg atoms controlled in optical tweezers, as well as novel techniques for matter wave interferometry. Our current investigations cover aspects of matter wave interferometry, quantum synchronization, and an exploration of computational complexity versus robustness with entangled atomic spins.

Our group studies the linear and nonlinear dynamics of light in photonic lattices and in semiconductor microcavities at the laboratory PhLAM of the Univeristy of Lille and the CNRS.

Our current projects are:

Lattice quantum electrodynamics in an open cavity
Synthetic lattices in coupled fibre rings
Out of equilibrium photon condensates and superfluids

The Photonics and Quantum Information (QPI) team at the institute of Physics of Nice, INPHYNI (UMR 7010 CNRS/Uni. Côte d’Azur, Nice, France) is one of the world experts in quantum photonics.

The experimental division of Quantum Computing, directed by Prof. Frederico Brito, is one of the 6 R&D divisions at the Quantum Research Centre (QRC) of the Technology Innovation Institute (TII) in Abu Dhabi, United Arab Emirates. TII is a non-profit state-funded organization that aims to become a major international hub for Science & Technology (https://www.tii.ae/).

Based at Insubria University, on the shore of Lake Como in Italy, the Quantum and Ultrafast Photonics (QUP) laboratory is at the forefront of research on quantum states of light, with over fifteen years of experience in quantum and nonlinear optics. Our expertise spans the generation of entangled photons in nonlinear media and their characterization, ultrafast nonlinear optics, innovative quantum imaging techniques, and advancements in integrated quantum photonics.

Cybersecurity based on Optical Quantum Communications

University of Padua opens a new research line in experimental quantum computing, with a new trapped ion laboratory. The experiment, trapping Barium ions, focuses on developing algorithms and protocols for quantum computing and simulations, and on the design of scalable quantum systems.

We study how the fundamental laws of quantum mechanics govern electronic transport in micro or nano-devices made of exotic quantum materials. In particular, topological phases represent an ideal playground with rich and exotic physics connected to the peculiar topological properties of the electronic wave functions in those materials.

The group led by Prof. Alexey Ustinov is located at the university campus of KIT and has a long successful record of exploring the physics of superconducting circuits, both classical and quantum. We are using superconducting qubits for state-of-the-art experiments, challenge new physics questions and explore opportunities for the next generation of quantum information processing. Our group pioneered frequency domain multiplexing readout of qubits, detection and manipulation of microscopic two-level defects, and studied qubit arrays as quantum metamaterials.
