Interesting study occurring on subatomic particles (aka neutrinos) in how they can be in superposition, without individual identities, when traveling hundreds of miles.
Now, MIT physicists have found that subatomic particles called neutrinos can be in superposition, without individual identities, when traveling hundreds of miles. Their results, to be published later this month in Physical Review Letters, represent the longest distance over which quantum mechanics has been tested to date.
A subatomic journey across state lines
The team analyzed data on the oscillations of neutrinos—subatomic particles that interact extremely weakly with matter, passing through our bodies by the billions per second without any effect. Neutrinos can oscillate, or change between several distinct “flavors,” as they travel through the universe at close to the speed of light.
By narrowing the bandgap of titania and graphene quantum dots.
Researchers have found a method of harvesting light.
Griffith University researchers have discovered significant new potentials for light harvesting through narrowing the bandgap of titania and graphene quantum dots.
The researchers for the first time have found a quantum-confined bandgap narrowing mechanism where UV absorption of the grapheme quantum dots and TiO2 nanoparticles can easily be extended into the visible light range.

If there’s one thing the world’s most valuable companies agree on, it’s that their future success hinges on artificial intelligence.
Google is continuing to invest heavily in deep learning at a time its head of machine learning, John Giannandrea, is calling the artificial intelligence spring (as opposed to the AI winter of earlier times). The company’s Founders’ letter this year mentions machine learning up to five times, leaving no doubt that it believes its advantages in this area will give it the edge in the coming years. In short, CEO Sundar Pichai wants to put artificial intelligence everywhere, and Google is marshaling its army of programmers into the task of remaking itself as a machine learning company from top to bottom.

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied concepts of classical holography to the world of quantum phenomena. A new measurement technique has enabled them to register the first ever hologram of a single light particle, thereby shedding new light on the foundations of quantum mechanics.
Scientists at the Faculty of Physics, University of Warsaw, have created the first ever hologram of a single light particle. The spectacular experiment, reported in the journal Nature Photonics, was conducted by Dr. Radoslaw Chrapkiewicz and Michal Jachura under the supervision of Dr. Wojciech Wasilewski and Prof. Konrad Banaszek. Their successful registering of the hologram of a single photon heralds a new era in holography: quantum holography, which promises to offer a whole new perspective on quantum phenomena.
“We performed a relatively simple experiment to measure and view something incredibly difficult to observe: the shape of wavefronts of a single photon,” says Dr. Chrapkiewicz.
