This research advances error mitigation in quantum computing by extending randomized compiling from discrete gates to continuous time processes, effectively addressing environmental memory effects that accumulate during operations. By utilizing the continuous process tensor framework, the study provides practical strategies for managing ongoing interactions between quantum systems and their surroundings, a critical step toward building reliable quantum processors.

Researchers Bound Quantum Process Errors Using Total Variation

Quantum ZeitgeistOctober 4, 20264 min read

Extending randomised compiling beyond isolated gates now allows accurate control of errors within evolving quantum systems. Continuous-process randomized compilation unifies random controls with environmental dynamics on a shared timescale, addressing how ‘memory’ affects calculations. Distinguishing logical transparency, interval classicalization, and operational decoupling represents a shift away from methods limited by boundary descriptions.

Precise control over quantum systems experiencing environmental memory has long been a key challenge to building practical technologies. Continuous-process randomized compilation (CPRC) extends existing randomized compiling techniques from discrete operations into continuous time processes, allowing detailed description of how errors evolve during an operation rather than just at its start and end points. The method better manages errors arising from environmental ‘memory’ affecting quantum calculations over time. Current approaches typically address mistakes after each distinct step, but CPRC…
