Tech giant Microsoft and leading quantum computer developer Quantinuum have hit two more significant markers on the path towards scientific quantum advantage. They have successfully created 12 highly reliable logical qubits and demonstrated a hybrid end-to-end chemistry simulation, utilising a combination of HPC, AI, and quantum. The logical qubit breakthrough was achieved on Quantinuum’s H2 trapped-ion 56 physical qubit quantum computer using Microsoft’s Azure Quantum’s qubit-virtualisation system. It triples the pair’s previous achievement of four reliable logical qubits, announced in April this year. The team also demonstrated several fault-tolerant computations with the improved logical qubits which, when entangled, have a…
