Overview
QubitAF aims at developping the potential of cold atom platforms that have already shown interest for quantum simulation: arrays of interacting atoms in optical tweezers and in optical lattices.
Keywords: Cold atoms, Quantum computation, Quantum simulation, Rydberg atoms, Optical lattices, Entanglement
In a nutshell
Afin de s’approcher des critères de l’ordinateur quantique, trois leviers ont été identifiés :In order to approach the criteria for quantum computing, we have identified three development directions:
- Increase the number of manipulated atoms
- Characterize and certify the results of quantum simulators with large numbers of atoms
- Study the role of dissipation on the performance of these platforms.
On the Rydberg platforms, we will increase the number of atoms, the fidelity of the operations and the total operation time. In parallel, we will develop and experimentally demonstrate original methods for platform certification, in particular for large atom number entanglement, which is central to obtaining a quantum advantage. Finally, we will build two new types of quantum simulators to study the many-body problem in a dissipative regime, with controlled dissipation.
This project gathers 3 teams of experimentalists, a team of theorists and the startup Pasqal with complementary skills, covering basic experimental developments, engineering of technological solutions, and exploration of applications, from the most fundamental to the most applied.
Challenges
- Develop the potential of cold atom platforms for quantum simulation and computation with very large numbers of atoms (more than 500). These platforms have already shown strong interest from industry, particularly with well-defined use cases.
Tasks
- WP1: Experimental developments towards the quantum computer, by improving simulators
- WP2: Development and testing of methods for characterizing N-body quantum states, and certification of simulator results
- WP3: Study of new academic and industrial use cases
- WP4: Setting up a web platform for on-line quantum simulation
