I remember the time when states of matter were pretty simple: Solid, liquid and gas. Then came plasma state, supercritical fluid, Bose –Einstein condensate and more. Now this list of states of matter has grown by one more, with the surprising discovery of a new state dubbed “dropletons” that shows some similarity to liquids but occur under very unlike circumstances.

The discovery of new state of matter occurred when a team of scientists at the University of Colorado Joint Institute for Lab Astrophysics were concentrating laser light on gallium arsenide (GaAs) to generate excitons.

Excitons are made when a photon strikes a material, mostly a semiconductor. If an electron is knocked loose, or excited, it leaves what is labelled as “electron hole” behind. If the forces of other charges at very close distance keep the electron close enough to the hole in order to feel an attraction, a certain state forms called as an Exciton. Excitons are also called quasiparticles because the holes and electrons act together as if they were like a single particle.

You’ve gotta love Star Trek, but there is absolutely NO WAY I’d ever set foot in a real teleportation device! (if one ever really got made, of course) Call me crazy, but I’m kinda partial to keeping my molecular cohesion as intact as possible, which kinda rules out having it ripped apart and remade on the other side.

A record-breaking distance has been achieved in the bizarre world of quantum teleportation, scientists say.

The scientists teleported photons (packets of light) across a spool of fiber optics 63 miles (102 kilometers) long, four times farther than the previous record. This research could one day lead to a “quantum Internet” that offers next-generation encryption, the scientists said.

For centuries, religious texts have explored the idea that reality breaks down once we get past our surface perceptions of it; and yet, it is through these ambiguities that we understand more about ourselves and our world. In the Old Testament, the embattled Job pleads with God for an explanation as to why he has endured so much suffering. God then quizzically replies, “Where were you when I laid the foundations of the earth?” (Job 38:4). The question seems nonsensical — why would God ask a person in his creation where he was when God himself created the world? But this paradox is little different from the one in Einstein’s famous challenge to Heisenberg’s “Uncertainty Principle”: “God does not play dice with the universe.” As Stephen Hawking counters, “Even God is bound by the uncertainty principle” because if all outcomes were deterministic then God would not be God. His being the universe’s “inveterate gambler” is the unpredictable certainty that creates him.

The mind then, according to quantum cognition, “gambles” with our “uncertain” reason, feelings, and biases to produce competing thoughts, ideas, and opinions. Then we synthesize those competing options to relate to our relatively “certain” realities. By examining our minds at a quantum level, we change them, and by changing them, we change the reality that shapes them.

The dimensionless aspect, since it has no dimensions, is outside of space and time. This is the key aspect to existence: an aspect outside of space and time perpetually interacting dialectically with an aspect inside space and time. All of the weird and wonderful phenomena of the universe are the products of this ultimate dichotomy.

Does this sound crazy? Then consider the evidence provided by black holes.

The R = 0 Universe.

In probability theory, the multi-armed bandit problem (sometimes called the K- or N-armed bandit problem) is a problem in which a gambler at a row of slot machines (sometimes known as “one-armed bandits”) has to decide which machines to play, how many times to play each machine and in which order to play them. When played, each machine provides a random reward from a distribution specific to that machine. The objective of the gambler is to maximize the sum of rewards earned through a sequence of lever pulls.

(Phys.org)—A combined team of researchers from France and Japan has created a decision-making device that is based on basic properties of quantum mechanics. In their paper published in Scientific Reports (and uploaded to the arXiv preprint server), the team describes the idea behind their device and how it works.

Researchers from Queen Mary University of London and Karlsruhe Institute of Technology have developed a model that applies ideas from the theory of complex networks, such as the brain or the Internet, to the fundamental quantum geometry of space-time.

The research is published in Scientific Reports with the title “Complex Quantum Network Manifolds in Dimension d > 2 are Scale-Free.” The research paper is freely available online.

“We hope that by applying our understanding of complex networks to one of the fundamental questions in physics we might be able to help explain how discrete quantum spaces emerge,” said author Ginestra Bianconi.

One of the most confounding implications of quantum physics is that light can behave as both a particle (photon) and a wave, depending on the nature of the observation. This is called wave-particle duality, and it has been extremely difficult to picture, let alone observe in both stages simultaneously. Now, physicists publishing in Nature Communications report that they have been able to capture a photograph of wave/particle duality ‘in action’, so to speak. This TED video explains the nature of the effect:
