Now, researchers at the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg have solved one of the longstanding problems in the field, namely, how a certain symmetry can be restored.  Researchers at the University of Chicago and Argonne National Laboratory have invented an innovative way for different types of quantum technology to "talk" to each other using sound.  Quantum secure direct communication (QSDC) is an important branch of quantum communication, based on the principles of quantum mechanics for the direct transmission of classified information.  The deluge of cyberattacks sweeping across the world has governments and companies thinking about new ways to protect their digital systems, and the corporate and state secrets stored within.  The Pentagon on Friday said there has been a cyber breach of Defense Department travel records that compromised the personal information and credit card data of U.S. military and civilian personnel.  Quantum secure direct communication transmits secret information directly without encryption.  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.
