All Things Quantum:

“The Mage’s of Tomorrow will be the Quantum manipulators of today”

Sub fields include: (wikipedia)
Quantum computing, which deals on the one hand with the question how and whether one can build a quantum computer and on the other hand, algorithms that harness its power (see quantum algorithm)
Quantum complexity theory
Quantum cryptography and its generalization, quantum communication
Quantum error correction
Quantum communication complexity
Quantum entanglement, as seen from an information-theoretic point of view
Quantum dense coding
Quantum teleportation is one well-known quantum information processing operation which reliably transfers an unknown quantum state from one point to another distant point, destroying the original state in the process

Plus many many more…..

Weird quantum effects stretch across hundreds of miles

Public Release: 19-Jul-2016   Massachusetts Institute of Technology CAMBRIDGE, Mass. — In the world of quantum, infinitesimally small particles, weird and often logic-defying behaviors abound. Perhaps the strangest of these is the idea of superposition, in which objects can exist simultaneously in two or more seemingly counterintuitive states. […]

Einstein wrong on quantum entanglement

Public Release: 24-Mar-2015 Quantum experiment verifies Einstein’s ‘spooky action at a distance’ Griffith University, University of Tokyo homodyne measurements show what Einstein did not believe to be real: the non-local collapse of a particle’s wave function Griffith University IMAGE: This is professor Howard Wiseman, Director of Griffith University’s […]

Atoms can be in 2 places at the same time

Public Release: 20-Jan-2015 Researchers of the University of Bonn have shown that cesium atoms do not follow well-defined paths University of Bonn The Bonn team has developed a measurement scheme that indirectly measures the position of an atom. In essence, one looks where the cesium atom is not. […]

Spooky alignment of quasars across billions of light-years

Artist’s Impression of Mysterious Alignment of Quasar Rotation Axes Caption: This artist’s impression shows schematically the mysterious alignments between the spin axes of quasars and the large-scale structures that they inhabit that observations with ESO’s Very Large Telescope have revealed. These alignments are over billions of light-years and […]
