Rydberg Atom Quantum Computing

Project: Third tier

Projectdetails

Omschrijving

The qubits in our platform are based on ultracold (Rydberg) atoms. With optical tweezers these atoms will be hold in a lattice configuration with good optical access, controllability and readout. Our lab contains an operational atomic Rubidium quantum computing testbed, and we are constructing a cloud-based quantum computing facility based on Strontium atoms. In both platforms, with the excitation to Rydberg states, strong nearest-neighbor coupling can be realised, giving rise to multi-qubit entanglement. These Ryberg platforms are very suitable for the execution of specific tasks such as hybrid algorithms for quantum chemical problems.

Omschrijving in begrijpelijke taal

Quantum computers are currently in the noisy intermediate scale quantum (NISQ) era, where noise and decoherence are still a major challenge for quantum computing platforms, and which also limits the scale of the machines that can be built. However, a combination of hardware-dependent optimization, hybridization with classical computing and clever algorithms can demonstrate quantum advantage for specific tasks. We develop a scalable platform along these principles, based on ultracold Rydberg atoms in optical tweezers.

The Rydberg atom platform is a development platform both for technology and for applications, and it will be available for the Dutch quantum ecosystem and beyond, via the Quantum Inspire facility, accessible 24/7 online. This project brings different areas of expertise together: the knowledge of fundamental atomic physics on interacting atoms, the development of hardware-specific hybrid quantum-classical algorithms, the experimental knowledge of laser cooling and quantum gases, and the engineering of all components to a full stack cloud-based quantum computer.
