A scalable network for simultaneous pairwise quantum key distribution via entanglement-based time-bin coding

Lucas Bialowons, Erik Fitzke, Maximilian Tippmann +4 more

We present simultaneous quantum key distribution (QKD) between any two pairs of participants in a 4-party star-shaped optical fiber network without a trusted node. Our QKD system is the first to extend an entanglement-based time-bin coding protocol to multiple pairs of participants. We demonstrate key exchange over distances of more than 75 km and show that our network can be readily extended to at least 34 participants by using wavelength-division multiplexing in the optical C-band and with small modifications up to 102 participants. Our scheme is compatible to multiplexing approaches that were implemented earlier with polarization-based QKD and can thereby be extended to a fully connected network. In contrast to polarization-based QKD, the all-fiber system we present is insensitive to polarization instabilities in the fiber link. This enables key distribution networks with low quantum bit error rates and stable secure key rates using deployed fibers even under challenging environmental conditions.

Distribution of GHz sequential Time-bin Entanglement in a Metropolitan Fiber Network

Martin Achleitner, Alessandro Trenti, Philip Walther +1 more

Efficient generation and high-quality distribution of entanglement is becoming increasingly more relevant in the field of quantum technologies, with important applications such as multiparty computation as well as quantum key distribution (QKD) on the rise. Quantum communication protocols based on entanglement offer an inherent quantum based randomness for key generation and provide in general higher security compared to prepare and measure implementations. Moreover, the future quantum internet will also be based on the distribution of entanglement for securely connecting quantum computers in a network. In this work we show the feasibility of using sequential time-bin entangled states for quantum key distribution in metropolitan networks using off-the-shelf components. The time-bin encoding ensures high fidelity distribution robust against random polarisation fluctuations occuring in optical fibers. Modulated laser pulses in the GHz frequency range are used to generate time-bin entangled photon pairs. The entangled photons are then sent over an about 30km long (9.5dB loss) fiber link within the Vienna fiber network, showing high degree of distributed entanglement with a measured 93\% quantum visibility.

Quantum communication with time-bin entanglement over a wavelength-multiplexed fiber network

Jin-Hun Kim, Jin-Woo Chae, Youn-Chang Jeong +1 more

In a quantum network involving multiple communicating parties, an important goal is to establish high-quality pairwise entanglement among the users without introducing multiple entangled-photon sources which would necessarily complicate the overall network setup. Moreover, it is preferable that the pairwise entanglement of photons is in the time-bin degree of freedom as the photonic time-bin qubit is ideally suited for fiber-optic distribution. Here, we report an experimental demonstration of a field-deployable quantum communication network involving multiple users, all of whom share pairwise entanglement in the time-bin degree of freedom of photons. In particular, by utilizing a single spontaneous-parametric down-conversion source which produces a broadband pair of photons and the wavelength-division demultiplexing/multiplexing technology, all the communicating parties within the network are always simultaneously ready for quantum communication. To further demonstrate the practical feasibility of a quantum network with time-bin entanglement over a wavelength-multiplexed fiber network, we demonstrate entangled-photon quantum key distribution with three users, each separated by 60 km of optical fibers.
