Abstract
A scheme is proposed for parallel teleportation of partially unknown quantum operations with multiple degrees of freedom based on a nitrogen-vacancy (NV) center system. An NV center system offers long coherence time and high fidelity for quantum operations. Assisted by the error heralded module and the corresponding circuit, high fidelity parallel teleportation of partially unknown quantum operations can be achieved, with hyperentangled Bell states of polarization and time-bin modes as the quantum channels. In the case of low side leakage and strong coupling, the efficiency and success probability approaching unity can be expectable. The employment of simple module circuits and optical components is beneficial for the implementation of the scheme with currently experimental techniques.
