Quantinuum unveils Helios, claims a massive leap toward practical quantum computing

The Helios hardware houses 98 physical qubits. But practical quantum computing isn't measured merely in quantity: physical qubits are vulnerable to minute environmental disturbances, which can produce errors even during short computations. The industry instead often focuses on "logical" qubits, which result when many physical qubits are interlinked via error-correction...
