IQM Quantum Computers Achieves Landmark Full-Chip Entanglement!

IQM Quantum Computers has successfully achieved simultaneous entanglement of all 54 qubits in its Emerald processor, a breakthrough that validates its full-chip performance. Users can now access the entire chip via IQM Resonance, up from a previous limit of 30 qubits. This milestone was reached after a year of calibration improvements, showcasing genuine multipartite entanglement with GHZ fidelity exceeding 0.516. The achievement enables advanced quantum algorithms and research at larger scales.
