Physicists use an interferometer to test whether standard quantum mechanics is correct, or whether a more complex version is required. They used the interferometer to send photons around a loop in opposite directions. In this way, photons travelling in one direction interact with objects inside the loop in one order, while photons travelling the opposite direction interact with objects in the opposite order.  Physicists at the Institute for Quantum Information and Matter at Caltech have discovered the first three-dimensional quantum liquid crystal—a new state of matter that may have applications in ultrafast quantum computers of the future.  For the first time, an experiment has directly imaged electron orbits in a high-magnetic field, illuminating an unusual collective behavior in electrons and suggesting new ways of manipulating the charged particles.  Scientists can now detect magnetic behavior at the atomic level with a new electron microscopy technique developed by a team from the The researchers took a counterintuitive approach by taking advantage of optical distortions that they typically try to eliminate.  Researchers at the Nanoscale Transport Physics Laboratory from the School of Physics at the University of the Witwatersrand have found a technique to improve carbon superlattices for quantum electronic device applications.  The researchers have found that these previously underestimated interactions can play a significant role in preventing heat dissipation in microelectronic devices.  LCLS works like an extraordinary strobe light: Its ultrabright X-rays take snapshots of materials with atomic resolution and capture motions as fast as a few femtoseconds, or millionths of a billionth of a second. For comparison, one femtosecond is to a second what seven minutes is to the age of the universe.  A 'nonlinear' effect that seemingly turns materials transparent is seen for the first time in X-rays at SLAC's LCLS.  Leiden physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been accomplished with actual atoms. It is an important step toward light-based quantum technology.
