This world-first nanophotonic device, just unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' light.  Purdue University researchers created a new technique that would increase the secret bit rate 100-fold, to over 35 million photons per second.  Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems.  Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers.  Calculations of a quantum system's behavior can spiral out of control when they involve more than a handful of particles.  Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing.  The key technical novelty of this work is the creation of semantic embeddings out of structured event data.  The researchers have focussed on a complex quantum property known as entanglement, which is a vital ingredient in the quest to protect sensitive data.  Cryptography is a science of data encryption providing its confidentiality and integrity.  Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure.
