Abstract
This disclosure is directed to a methods and systems for establishing a long-range quantum link in a quantum communication network and for improving connection rate of the quantum link. The quantum link is established across multiple quantum repeaters relying on quantum entanglement swap operations in the multiple quantum repeaters. The methods and systems use nested connection loops that are started as soon as quantum repeater resources become available. As such, another connection loop having a head start can be used to continue achieving the quantum link when one connection loop fails, thereby improving the connection rate for the quantum link.
