Quantum Machines and Academia Sinica speed up qubit tuning with AI

Quantum Machines and Academia Sinica have dramatically accelerated a critical step in quantum computing, reducing two-qubit gate calibration from approximately 15 minutes to just 25 seconds. This speed-up, achieved by directly connecting Quantum Machines’ OPX1000 controller to a classical GPU accelerator via OPNIC, enables real-time hardware feedback for a reinforcement learning agent, the company says. Beyond single gates, the agent simultaneously optimized all parameters of a five-qubit circuit to prepare a GHZ state, demonstrating a path toward continuous calibration for larger quantum processors. This speed-up addresses a critical bottleneck in scaling quantum processors, where maintaining calibration across hundreds or even thousands of qubits demands faster, more autonomous routines capable of optimizing numerous parameters simultaneously. The core of this advancement lies in the direct connection of Quantum Machines’ OPX1000 controller to the GPU via OPNIC, a technology that enables the rapid exchange of data crucial for the agent’s learning process, according to the company.
