Now University of Rochester researchers have succeeded in creating particles with negative mass in an atomically thin semiconductor, by causing it to interact with confined light in an optical microcavity.  The device is a type of spectrometer—an optical instrument that takes light and breaks it down into components to reveal a catalogue of information about an object.  When we look at a painting, how do we know it's a genuine piece of art?  Researchers from the University of Illinois at Urbana-Champaign have demonstrated a new level of optical isolation necessary to advance on-chip optical signal processing. The technique involving light-sound interaction can be implemented in nearly any photonic foundry process and can significantly impact optical computing and communication systems.  City College of New York researchers have now demonstrated a new class of artificial media called photonic hypercrystals that can control light-matter interaction in unprecedented ways.  Experiments at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw prove that chemistry is also a suitable basis for storing information. The chemical bit, or 'chit,' is a simple arrangement of three droplets in contact with each other, in which oscillatory reactions occur.  Researchers at Sandia National Laboratories have developed new mathematical techniques to advance the study of molecules at the quantum level.  Correlation functions are often employed to quantify the relationships among interdependent variables or sets of data. A few years ago, two researchers proposed a property-testing problem involving Forrelation for studying the query complexity of quantum devices.  A team of researchers from Australia and the UK have developed a new theoretical framework to identify computations that occupy the 'quantum frontier'—the boundary at which problems become impossible for today's computers and can only be solved by a quantum computer.  Scientists at the University of Sussex have invented a groundbreaking new method that puts the construction of large-scale quantum computers within reach of current technology.  Physicists at the University of Bath have developed a technique to more reliably produce single photons that can be imprinted with quantum information.
