ID Quantique (IDQ), the world leader in quantum-safe security solutions, today launched the Cerberis XG at the Inside Quantum Technology conference (IQT). This is the first of a series, aiming at providing the highest level of trust to governments and enterprises for future proof data protection in smaller and optimized form factor, once and for […]
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, […]

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 […]

Telefónica Tech has collaborated with Barcelona-based startup Quside, and New York-based Qrypt to successfully complete the integration of a new quantum technology into its cloud service hosted in its Virtual Data Centers (VDC). Telefónica Tech is a holding company owned by the Telefónica Group. The company offers a wide range of integrated technological services and […]
Simplified measurement setup for demonstrating a QKD experiment with the receiver chip.
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 […]
Nondestructive detection of photonic qubits - NPQD applications
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 […]
Spatial Mode Correction of Single Photons Using Machine Learning
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 […]
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 […]
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 […]
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 […]
