Development of subsystems for quantum-secure information transmission using Quantum Repeaters

The BMFTR-funded joint project “Q.com” aimed to develop and build a Quantum Repeater – an endeavor that required close cooperation between physics and communications engineering. Accordingly, Q.com was structured into three subprojects: quantum-optical components (project Q.com-Quantenoptik: Quantenspeicher aus Atomen und Molekülen) were combined with semiconductor devices (project Q.com-Halbleiter: Einzelphotonenquellen aus Quantenpunkten) to efficiently realize the functionalities required for Quantum Repeaters. On this basis, the foundations of novel components were investigated. In addition, the subproject Q.com-Nachrichtentechnik developed secure quantum-cryptographic transmission protocols for repeater links.

Within the funding priority area of Quantum Communication, the physical foundations for building a Quantum Repeater Link were also a central focus. Furthermore, technologies for data transmission over conventional fiber-optic networks were investigated in order to enable the future integration of Quantum Repeaters into existing infrastructures with minimal effort. Another key emphasis was placed on theoretical concepts that enable provably secure Quantum Communication.
