Project description
Towards practical, secure quantum networks based on diamond flaws
A long-sought goal for realising robust quantum networks is to distribute entanglement across large distances. Such networks could enable the implementation of distributed quantum computing, unconditionally secure communication and ultra-precise quantum-logic clocks. Funded under the Marie Skłodowska-Curie programme, the IQubitNet project aims to develop quantum repeater devices that harness the promising spin and optical properties of group-IV colour centres in diamonds coupled to nanocavity interfaces. The project plans to demonstrate that such quantum repeaters can overcome fundamental scaling limits of quantum communications that do not use repeaters, enabling a new generation of multi-node quantum networking applications.
Objective
The rapidly advancing field of quantum technologies promises to solve important problems in computation, communication and metrology. A long-sought goal is the realization of quantum networks to distribute entanglement to long distance nodes. Such a network could enable the implementation of distributed quantum computing, unconditionally secure communication, ultra-precise distributed clocks, and precision sensors such as ultra-long-baseline interferometers. While ground-breaking demonstrations have been reported using NV centers in diamond, scaling up the performance and range will require key advances in suppressing photon loss, extending decoherence, and multiplexing and packaging deployable quantum repeater nodes.
In this project, we propose to investigate the promising spin and optical properties of Group-IV color centers in diamond coupled to nanocavity interfaces, and to scale these Cavity-QED systems to multiple quantum memories individually addressable on photonic integrated circuits (PICs). The multiplexed quantum repeater devices that we propose will combine highly efficient optical interfaces with logical qubit of extended coherence. Moreover, these repeater nodes can be efficiently connected over long distance through existing metropolitan-scale fiber networks by quantum frequency conversion to the telecom band. As a specific goal, we aim to demonstrate that such quantum repeaters will be able to beat the rate-loss scaling of repeaterless (memoryless) quantum links, enabling a new generation of multi-node quantum networking application.
