Project description
Unhackable quantum keys could soon be sent with satellites
Quantum key distribution is a secure communication method for exchanging encryption keys only known between two parties. The technique already works in fibre optic cables but for relatively short distances of about some hundred kilometres as the signal gradually fades. The use of satellites could help overcome transmission losses and enable quantum key distribution on a global scale. Continuous variable protocols, which are based on standard telecommunication detection technology, have proven to be fast and efficient in fibre optic channels. Funded by the Marie Skłodowska-Curie Actions programme, the SatCV project will extend these protocols to the free-space domain. Project work will pave the way towards sending secret quantum keys with satellites in the future.
Objective
Quantum Key Distribution (QKD) allows two parties to exchange a cryptographic key in an unconditionally secure way. Thus, this system will be secure even after the development of a quantum computer, which is thought to efficiently break current key exchange mechanisms based on public-key cryptography. While most current QKD implementations are fiber-based, its intrinsic limitation to some hundred kilometers, due to fiber losses, makes satellite QKD a crucial technology for the establishment of a secure link at a world-wide scale. The research on satellite QKD has mainly focused on discrete variable (DV) protocols, which are less sensitive to channel transmission but require single photon detection technology. Continuous variable (CV) protocols, on the other hand, are based on standard telecom detection technology, which is much faster and more efficient. Recently, CV protocols have shown to work well in high losses fiber-based environments. This action aims to extend the CV scheme to the free-space domain, implementing a full, self-referenced CV-QKD scheme on a free-space channel, as a first step for a future satellite implementation of such technology.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
