Researchers Bound Quantum Process Errors Using Total Variation

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…
