Harvard and QuEra run algorithms on 48 logical qubits

QuEra Computing/Aquila and gate-based systems

In Nature, Harvard, QuEra, MIT and NIST/University of Maryland researchers reported a programmable processor of encoded logical qubits using up to 280 physical neutral atoms. They ran algorithms on up to 48 logical qubits with hundreds of logical entangling operations.

• Up to 280 physical neutral atoms used to encode logical qubits in a single array.
• 48 logical qubits demonstrated; ran algorithms with hundreds of logical entangling operations.
• Programmable processor shows scaling toward larger logical-qubit systems.
• Multi-institution collaboration (Harvard, QuEra, MIT, NIST/UMD) published in Nature.
