Researchers have developed a framework for determining the optimal size of quantum memories needed to store distilled Einstein-Podolsky-Rosen (EPR) pairs, a crucial component of the quantum Internet1. This framework utilizes a Markov chain model to capture the dynamics of EPR pair distillation and storage, allowing for the efficient management of quantum error correcting codes. The proposed approach enables the transmission of quantum information over long distances, a key requirement for the development of a functional quantum Internet. By dimensioning quantum memories appropriately, researchers can mitigate the effects of quantum noise and errors, paving the way for the creation of a reliable and secure quantum communication network. The ability to store and transmit distilled EPR pairs has significant implications for the field of quantum computing and cryptography, as it enables the creation of secure quantum channels for sensitive information transmission, so what matters to practitioners is that this breakthrough has the potential to elevate the security of quantum communication systems.
