Shadow simulation of quantum processes
arxiv(2024)
摘要
We introduce the task of shadow process simulation, where the goal is to
reproduce the expectation values of arbitrary quantum observables at the output
of a target physical process. When the sender and receiver share classical
random bits, we show that the performance of shadow process simulation exceeds
that of conventional process simulation protocols in a variety of scenarios
including communication, noise simulation, and data compression. Remarkably,
shadow simulation provides increased accuracy without any increase in the
sampling cost. Overall, shadow simulation provides a unified framework for a
variety of quantum protocols, including probabilistic error cancellation and
circuit knitting in quantum computing.
