Key Device and Materials Specifications for a Repeater Enabled Quantum Internet

Entangled photons can be used to create a truly secure communication link between two parties. However, the distance over which this can be achieved is limited by the transmission losses associated with optical fibers. One potential solution is using quantum repeaters (QRs) where initial entanglement is created over short distances and then extended via entanglement […]

Attacking the Quantum Internet

The main service provided by the coming quantum Internet will be creating entanglement between any two quantum nodes. We discuss and classify attacks on quantum repeaters, which will serve roles similar to those of classical Internet routers. We have modeled the components for and structure of quantum repeater network nodes. With this model, we point […]

Hybrid Dissipative and Dispersive Optomechanically Induced Transparency

Traditionally, the optical interference and energy conversion could be modulated by dissipation and dispersion in nonlinear optomechanical systems. Here, in this article, we study the enhancement of dissipative coupling on transparency under generalized optomechanical coupling and theoretically illustrate the generation of optomechanically induced transparency with gain and interference tuning. It enables the enhancement of the […]
