Abstract

Quantum memories are a fundamental of any global-scale quantum Internet, since these units are necessary for guaranteeing an optimal performance in a high-performance quantum networking scenario. The main problem of quantum memories is the low retrieval efficiency of the systems from the registers of the quantum memory. Here, we define a novel quantum memory called high-retrieval-efficiency (HRE) quantum memory for the quantum Internet. An HRE quantum memory unit integrates local unitary operations on its hardware level for the optimization of the readout procedure and utilizes the advanced techniques of quantum machine learning. The local unitaries of an HRE quantum memory achieve the optimization of the readout procedure in an unsupervised manner without the use of any labeled data or training sequences. The HRE quantum memory is a particularly convenient unit for the construction of a powerful, global-scale quantum Internet.
