Dutch researchers establish the first entanglement-based quantum network

Towards ubiquitous connectivity The first steps towards a quantum internet were taken in the past decade by linking two quantum devices that shared a direct physical link. However, being able to pass on quantum information through intermediate nodes (analogous to routers in the classical internet) is essential for creating a scalable quantum network. In addition, […]

Dutch researchers establish the first entanglement-based quantum network

A team of researchers from QuTech in the Netherlands reports realization of the first multi-node quantum network, connecting three quantum processors. In addition, they achieved a proof-of-principle demonstration of key quantum network protocols. Their findings mark an important milestone towards the future Quantum Internet. The first steps towards a quantum internet were taken in the […]

Detector-integrated on-chip QKD receiver for GHz clock rates

Quantum Key Distribution (QKD) can greatly benefit from photonic integration, which enables implementing low-loss, alignment-free, and scalable photonic circuitry. At the same time, Superconducting Nanowire Single-Photon Detectors (SNSPD) are an ideal detector technology for QKD due to their high efficiency, low dark-count rate, and low jitter. Researchers have developed a QKD receiver chip featuring the […]

Detecting photons transporting qubits without destroying quantum information

Researchers at the Max Planck Institute of Quantum Optics have developed a detection method that can be used to track quantum transmissions. Quantum information is sent over long distances in the form of photons which are quickly lost. Finding out after only a partial distance whether such a photon is still on its way to its […]

Smart quantum technologies for secure communication

Researchers from Louisiana State University have introduced a smart quantum technology for the spatial mode correction of single photons. The team has exploited the self-learning and self-evolving features of artificial neural networks to correct the distorted spatial profile of single photons. The newly developed technique boosts the channel capacity of optical communication protocols that rely […]

New quantum-proof cryptography scheme

Here is a very interesting article written by Alec Edgington, Cameron Foreman and Duncan Jones of Cambridge Quantum Computing (CQC). In this paper, the team explains how at CQC they adopted a revolutionary approach to generating provably-perfect entropy, which they use to create quantum-proof cryptographic keys (both classical and post-quantum). They share the results of […]

Experimental quantum homomorphic encryption

Quantum computers promise not only to outperform classical machines for certain important tasks, but also to preserve privacy of computation. For example, the blind quantum computing protocol enables secure delegated quantum computation, where a client can protect the privacy of their data and algorithms from a quantum server assigned to run the computation. However, this […]

Quantum effects help minimize communication flaws

A collaboration between the Universities of Hong-Kong, Grenoble and Vienna, as well as the Austrian Academy of Sciences has revealed novel techniques to reduce noise in quantum communication. The primary approach to overcome these noise limitations is the application of so-called quantum error-correcting codes. This, however, requires an amount of resources exceeding that which can […]
