Key Highlights
- ➤54-qubit IQM Emerald processor fully entangled simultaneously across the entire chip
- ➤Full-chip cloud access now lets customers use all 54 qubits in one computation
- ➤Fidelity reached 0.516 at 54 qubits with readout error mitigation applied
- ➤Quantum-operation error rates fell by up to 50% after hardware and calibration improvements
Expert Statements
Craig Ciesla, CTO, IQM Quantum Computers
“Entangling the entire chip means every qubit and every connection between them has to work correctly in the same circuit. Getting there came down to being smarter about how we prepare the state itself, choosing the gate order to keep idle time to a minimum”
Craig Ciesla, CTO, IQM Quantum Computers
“Our current and prospective cloud customers now have the chance to benefit from the same tools and system performance that made this achievement possible.”
IQM Demonstrates Entanglement Across a Complete 54-Qubit Processor, Bringing Full-Chip Performance to Cloud Users
An automated state-preparation routine and enhanced calibration protocol keep fidelity above the entanglement threshold at full scale, and cloud users now have access to the same system performance.
