Quantum circuit simulation of superchannels

Blog Article

Quantum simulation is one of the central discipline to demonstrate the power of quantum computing.In recent years, the theoretical framework of quantum superchannels has been developed and applied widely as the extension of quantum channels.In this work, we study the quantum circuit simulation task of superchannels.We develop a quantum superchannel simulation Clutch Boss algorithm based on the convex decomposition into sum of extreme superchannels.We demonstrate the algorithm by numerical simulation of qubit superchannels with high accuracy, making it applicable to current experimental platforms.

Our study stands as an expansion of the superchannel theory Eyeshadow Brushes to the field of quantum simulation and algorithm, as well as an extension of quantum simulation from channels and open-system dynamics to superchannels and processes with manifest quantum memory effects.
