Quantum Computing Milestones: IQM Achieves Record Fidelity and Coherence Time

IQM Quantum Computers, a prominent player in the field of superconducting quantum computing, has reached significant milestones in two key metrics characterizing the quality of quantum computers. The company has demonstrated a record low error rate for two-qubit operations, achieving a CZ gate between two qubits with 99.91% fidelity, as well as impressive coherence times, including a qubit relaxation time (T1) of 0.964 milliseconds and dephasing time (T2 echo) of 1.155 milliseconds.

The achievement of high two-qubit gate fidelity is particularly noteworthy, as it is the most fundamental and hardest to achieve characteristic of a quantum processor. This milestone is essential for generating entangled states between qubits and executing quantum algorithms. The results were validated using interleaved randomized benchmarking, a rigorous method for assessing the performance of quantum gates.

The coherence times demonstrated by IQM are also among the key metrics for assessing the performance of a single qubit. These times indicate how long quantum information can be stored in a physical qubit and are critical for the development of reliable and efficient quantum computers. The results show that IQM’s fabrication technology has matured, paving the way for the next generation of high-performance quantum processors.
