A practical way to link separate nodes in quantum networks is to send photons over the standard telecom fibre network. This requires sub-Poissonian photon sources in the wavelength band around 1550 nm, with photon coherence times […]
A team of Chinese researchers has succeeded in sending entangled quantum memories between buildings 20 kilometers apart and over a 50-kilometer coiled fiber cable. The first experiment was based on the use of a small […]
Scotiabank in Canada has begun to explore the migration to encryption methods that can keep out the hackers. The bank is already thinking about the implications for data security and moving to quantum-safe encryption methods. […]
An international team of researchers from the Austrian Academy of Sciences (ÖAW) and the University of Vienna have established a quantum encrypted connection between Malta and Sicily (192 km) via a conventional submarine telecommunications cable […]
Researchers at ETH Zürich and National University of Singapore have carried out a study investigating whether advantage distillation, a classical cryptography technique that has so far never been successfully implemented, can be applied to device-independent […]
Quantum Xchange announced the availability of Post-Quantum Cryptography (PQC) algorithms to its Phio Trusted Xchange key distribution system.
BGN Technologies, the technology-transfer company of Ben-Gurion University of the Negev (BGU), Israel, is introducing the first all-optical stealth encryption technology that will be significantly more secure and private for highly sensitive cloud-computing and data […]
Toshiba and Tohoku University have achieved what they call the world’s first use of quantum cryptography to transmit genome sequence data. The information, collected from 24 people in a Toshiba-Tohoku project, was transmitted roughly 7 km over […]
Scientists from the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago launched a new testbed for quantum communication experiments. The Argonne quantum loop consists of a pair of connected 26-mile fiber-optic cables as 52 total […]
Editor’s note: This post is not directly linked to quantum computing or technology but we do think it may interest our readers. Banco Bradesco, a prominent Brazilian financial institution, has been working with IBM Research […]
As the building block in symmetric cryptography, designing Boolean functions satisfying multiple properties is an important problem in sequence ciphers, block ciphers, and hash functions. However, the search of n-variable Boolean functions fulfilling global cryptographic constraints […]
China’s quantum communication satellite, Quantum Experiments at Space Scale (QUESS) nicknamed Micius, has successfully linked up with the world’s first mobile quantum ground station and conducted an encrypted data transmission when the satellite was approximately […]
Researchers of the University of Twente found a new way to protect data from attacks using quantum computers. Single particles of light in Standard Quantum Key Distribution (QKD) systems are already being used to protect […]
Entanglement is exploited for applications in secure quantum communication over long distances and quantum cryptography protocols. Unfortunately, entangled particles are easily disturbed by their surroundings, and their entanglement is readily diminished by the slightest interaction […]
Cambridge Quantum Computing has integrated its IronBridge 4-qubit quantum photonics cryptographic device with IBM Key Protect and can demonstrate the generation of post-quantum secure keys. This solution requires minimal changes to existing infrastructure and interfaces natively with […]
KETS Quantum Security and CryptoNext announce partnership to build comprehensive quantum-safe solutions. The partnership will allows both companies to build fully-integrated quantum-safe security solutions, designed to fight the potentially catastrophic security threat brought by quantum […]
Researchers at Bar-Ilan University demonstrated that long sequences with certified randomness by the US National Institute of Standard and Technology (NIST) are far from being truly random.
Researchers have developed a quantum communication chip that is 1,000 times smaller than current quantum setups, but offers the same superior security quantum technology is known for.
Nu Quantum, the Cambridge-based quantum photonics company, raised a £650,000 pre-seed investment round led by Amadeus Capital Partners, with support from IQ Capital, Ahren Capital, Cambridge Enterprise and Martlet Capital, the investment arm of Marshall […]
In September 2019, the European Commission (EC) announced the launch of OPENQKD, a €15 million worth project aimed to provide test quantum communication infrastructures in several European countries. Four Swiss Geneva-located firms, The University of […]
