Multi-output programmable quantum processor

A multi-output programmable quantum processor was proposed. As a result of three restrictions, the processor was approximate and probabilistic, and the set of operations which it can implement was restricted. With a probability of 1/2, this yields approximately two transformed data outputs with a fidelity of 5/6, which can be distributed to the next processors for different tasks, respectively. Due to the property of entanglement, the data registers in the terminal can be separately located, even far from the processor if it allows local operation and classical communication.
