Researchers have successfully used mid-circuit measurements on a superconducting quantum processor to resolve individual trajectories in many-body systems, moving beyond traditional ensemble averages. This breakthrough allows for the direct observation of glass-like dynamical heterogeneity and scaling behaviors previously hidden by noise and averaging effects. The study validates current hardware capabilities for probing complex quantum dynamics at the trajectory level.

Researchers Find Glass Behaviour on Quantum Computer

Quantum ZeitgeistSeptember 7, 20263 min read

Can complex systems exhibiting glass-like behaviour be probed one trajectory at a time using today’s quantum computers? Measurements on a superconducting processor now demonstrate that detailed observation *is* possible, revealing how inactivity spreads through the system via analysis of space-time regions. This establishes present day processors as platforms capable of studying these dynamics beyond ensemble averages.

Mid-circuit measurements provide direct access to trajectory-level observables, revealing dynamical structures in many-body systems previously hidden within ensemble-averaged quantities. This capability was used to realise and study an instance of the Floquet-East model on a superconducting quantum processor. The interplay between mid-circuit measurements, kinetically constrained unitary operations and hardware noise generates…
