Quantum Security News
Researchers at the Kastler Brossel Laboratory in Paris have succeeded in implementing a quantum “hybrid” entanglement swapping protocol. The team has demonstrated a way of connecting different types of quantum nodes that are not necessarily
Researchers at the University of Science and Technology of China have recently introduced a new satellite-based Quantum-Secure Time Transfer (QSTT) protocol that could enable more secure communications between different satellites or other technology in space.
The first Quantum Key Distribution (QKD) protocol has been proposed by Bennett and Brassard in 1984. Since then, the security of QKD has always been the central issue in the quantum cryptographic field. Trace distance
Distributing entangled photon pairs over noisy channels is an important task for various quantum information protocols. Encoding an entangled state in a decoherence-free subspace (DFS) formed by multiple photons is a promising way to circumvent
Crypta Labs, a startup specialist in Quantum Random Number Generator (QRNG) technology, has signed up to the national SPRINT (SPace Research and Innovation Network for Technology) business support programme to develop its QRNGs for space
ID Quantique (IDQ), the Swiss quantum-safe security solutions company, announced that its newest Quantum Random Number Generator (QRNG) chip has been integrated in the ‘Galaxy A Quantum’, a custom edition of the Samsung Galaxy A71
KT has made a field test success that encrypts and transmits 5G data with a quantum cryptographic communication technology developed in Korea. This test is the most basic step in launching a service with the
A team from the US Department of Energy’s Oak Ridge and Los Alamos national laboratories led a QKD demonstration in power grid hosted by EPB, a community-based utility and telecommunications company. Using an isolated portion
Scientists at the Institute of Science and Technology Austria (IST Austria) have demonstrated a new type of detection technology called microwave quantum illumination that utilizes entangled microwave photons as a method of detection. The prototype,
As the search continues for useful applications of noisy intermediate scale quantum devices, variational simulations of fermionic systems remain one of the most promising directions. A team at Google AI Quantum has performed a series
