Record Logical Entanglement
Partnering with Microsoft, Quantinuum successfully generated 12 reliable logical qubits from just 56 physical qubits on their H2 QCCD trapped-ion system, demonstrating an error rate 800 times lower than bare physical qubits.
Derivation & Evidence
These are the precise 2024 performance metrics drawn from the report. In research collaboration with Microsoft, they fully validated 12 error-corrected logical models using just a 56-physical-qubit environment (the H2 platform), resulting in an incredibly efficient 4.6-to-1 overhead ratio, fundamentally proving fault tolerance viability.
