A recent study led by Princeton University researchers, in collaboration with University of Maryland and IBM, explored the architectural design of quantum computers (QC).  In the paper titled "Statistical Assertions for Validating Patterns and Finding Bugs in Quantum Programs," Huang and Margaret Martonosi, a professor of Computer Science at Princeton, identify three key difficulties in debugging quantum programs, and evaluate their solutions in addressing those difficulties.  Researchers at the University of Chicago published a novel technique for improving the reliability of quantum computers by accessing higher energy levels than traditionally considered.  An international team of researchers has taken an important step towards solving a difficult variation of this problem, using a statistical approach developed at the University of Freiburg.  Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds.  Electronics could work faster if they could read and write data at terahertz frequency, rather than at a few gigahertz.  A team of researchers led by the Department of Energy's Oak Ridge National Laboratory has demonstrated a new method for splitting light beams into their frequency modes.  Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution".  Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information.  Theoretical physicists propose to use negative interference to control heat flow in quantum devices.
