High-fidelity gates towards error correction with neutral atoms
Researchers at CESQ, Princeton and Yale have achieved the demonstration of high-fidelity one- and two-qubit gates with neutral ytterbium atoms, and of a way to identify when errors occur in quantum computers more easily than ever before. The family of two-qubit gates has been invented by Sven Jandura and Guido Pupillo at the CESQ within the Quantum Flagship project EuRyQa and the MSCA project “MOQS – Molecular quantum simulations”. Qubits are encoded into metastable states of the atoms, which facilitates the detection of errors in mid-circuit measurements and their conversion into erasure errors that are easier to deal with in the context of fault-tolerant quantum computing. The results were published in Nature. These gates have also been realized in a recent experiment with rubidium atoms at Harvard, achieving a record 99.5% fidelity. READ THE PAPER
Quantum Computing for Chemistry
Registrations are now open for the second edition of the training Quantum Computing for Chemistry co-organised by the University of Strasbourg (CESQ) and Qunasys. The training is open to anyone from industry, academia and students interested in quantum computing. For more information, please visit https://q4chem.eu/
The new CESQ building will be inaugurated on Oct. 16-17. Stay tuned for a scientific program!
