Alternate qubit design does error correction in hardware | Early-stage technology has the potential to cut qubits needed for useful computers
Early-stage technology has the potential to cut qubits needed for useful computers.
The technology underlying this work is termed a bosonic qubit, and they're not anything new; an optical instrument company even has a product listing for them that notes their potential for use in error correction. So there's no question that Nord Quantique is well behind a number of the leaders in quantum computing that can perform (error-prone) calculations with dozens of qubits and have far lower error rates. Over the next year, the company expects to demonstrate that the error correction scheme can function while pairs of qubits are used to perform gate operations, the fundamental units of calculations.
