A Norwegian University of Science and Technology team, working with an international group led by Copenhagen's Niels Bohr Institute, cut measurement time to about 10 milliseconds from roughly one second.
The technique tracks fluctuating relaxation rates in superconducting qubits in near real time, exposing rapid changes previously missed and helping identify why quantum information disappears unpredictably.
Researchers say the advance could improve testing and tuning of quantum processors, addressing a major barrier to making quantum computers stable, reliable and practical.
With a new 'quantum stethoscope' tracking errors 100x faster, can we finally build the perfect qubit material?
As scientists watch quantum data vanish in real-time, is the industry's race for more qubits missing the point?
Real-Time Quantum Data Loss Tracking at Millisecond Scale: The 2026 Breakthrough Enabling Reliable Quantum Computers
Overview
In February 2026, researchers from NTNU and the Niels Bohr Institute introduced a groundbreaking method for tracking quantum data loss in real-time, published in Physical Review X. This ultra-fast technique allows scientists to precisely monitor how quickly quantum information vanishes, measuring information loss in superconducting qubits in just 10 milliseconds—a dramatic improvement over previous one-second methods. This substantial reduction in measurement time is critical for accelerating quantum research and directly addresses one of the biggest challenges in building reliable quantum computers, providing crucial insights into the delicate nature of quantum states.
