Overview

• The team from the Niels Bohr Institute, MIT, NTNU, and Leiden published the approach in PRX Quantum on August 26, 2025.
• The method, called Frequency Binary Search, runs on a Quantum Machines controller with an integrated FPGA to avoid slow data round‑trips to a desktop computer.
• Experimental validation was carried out at MIT with collaborators Lukas Pahl and Melvin Mathews, confirming real‑time tracking of qubit frequency fluctuations.
• The authors say the technique can handle many qubits and different qubit types, with calibration requiring fewer measurements than conventional routines.
• According to the researchers, the procedure can achieve exponential precision with under 10 measurements and is accessible thanks to Python‑like FPGA programming tools.
