Scientists Have Made a Blueprint For a Quantum Battery That Never Loses Charge

Posted by in categories: mobile phones, quantum physics

A team of scientists from the universities of Alberta and Toronto have laid out the blueprints for a “quantum battery” that never loses its charge.

To be clear, this battery doesn’t exist yet — but if they figure out how to build it, it could be a revolutionary breakthrough in energy storage.

“The batteries that we are more familiar with — like the lithium-ion battery that powers your smartphone — rely on classical electrochemical principles, whereas quantum batteries rely solely on quantum mechanics,” University of Alberta chemist Gabriel Hanna said in a statement.

Posted by in categories: food, quantum physics, sustainability

From raindrops rolling off the waxy surface of a waterlily leaf, to the efficiency of desalination membranes, interactions between water molecules and water-repellent “hydrophobic” surfaces are all around us. The interplay becomes even more intriguing when a thin water layer becomes sandwiched between two hydrophobic surfaces, KAUST researchers have shown.

In the early 1980s, researchers first noted an unexpected effect when two hydrophobic surfaces were slowly brought together in water. “At some point, the two surfaces would suddenly jump into contact—like two magnets being brought together,” says Himanshu Mishra from KAUST’s Water Desalination and Reuse Center. Mishra’s lab investigates water at all length scales, from reducing water consumption in agriculture, to the properties of individual water molecules.

The men claimed they were abducted

Posted by in categories: biotech/medical, quantum physics

As an experiencer, I believe most claims are real. Whether they were man-made or actual exterrestials or exterrestials that work with us it is still a very common phenomenon. There have been several sightings essentially where even the person’s shoes were the only things left. Looking from common science fiction even it is a possibility that Emelia Airhart was teleported by aliens somewhere in the galaxy and can be referenced from the reports on star trek the tv show. There are several missing people that even today with good forensics that hardly anyone can find and the oddity of it all essentially says that essentially there were no traces left like literally none not even DNA. Looking through police records sure there are cold cases but most are solved but there are several cases that even the highest technologies of forensics have not solved. There are several cold cases all around the globe that were not ordinary ones they were, in fact, alien signs. But eventually, with quantum radar we could scan the entire universe to eventually find traces and digitize them finding a sorta batman style way of like forensics but you would need massive hardware but eventually, you could find them or anything in time. If they found Emelia Airhart they will find anyone else if these exist on this universe or even the multiverse if they physically exist. Then they would actually prove that aliens do actually exist aswell. Really nothing is impossible only improbable. Believing in aliens is not as far fetched as it seems. Most of their technology is science-based anyway it is just exotic physics.


The site of the 1973 alleged abduction is getting a historical marker.

It From Bit — Entropic Gravity For Pedestrians

Posted by in categories: cosmology, information science, quantum physics

Two and a half months since Erik Verlinde submitted his entropic gravity paper, and all of physics and cosmology has turned into entropy. Well, I am exaggerating a bit, and perhaps more than just a bit. Yet, fact is that within two weeks of Erik’s publication a steady stream of ‘entropic everything’ papers has developed at a rate of close to one paper per day. Gravity, Einstein’s equations, cosmic expansion, dark energy, primordial inflation, dark mass: it’s all entropic. Chaos rules. Entropy is king!

Or is it?

Could it be that an ‘entropic bandwagon’ has started rolling? Is this all not just a fad appealing to scientist tired of string theory? What is this elusive entropic force anyway? Do these folks really believe bits of information attract each other?

Squeeze leads to stellar-mass black hole collision precision

Posted by in categories: cosmology, quantum physics

Scientists at The Australian National University (ANU) have found a way to better detect all collisions of stellar-mass black holes in the universe.

Stellar-mass black holes are formed by the gravitational collapse of a star. Their collisions are some of the most violent events in the universe, creating or ripples in space-time.

These ripples are miniscule and detected using laser interferometers. Until now, many signals have been drowned out by so-called on the pushing the mirrors of the laser interferometer around—making the measurements fuzzy or imprecise.

The Race For Quantum Supremacy I VICE on HBO

Posted by in categories: biotech/medical, cybercrime/malcode, quantum physics

Computer giants are racing to build the first quantum computer, a device with millions of times more processing strength than all the computers currently on Earth combined. This technology will harness the unusual laws of quantum mechanics to bring unimaginable advances in fields like materials science and medicine, but could also pose the greatest threat to cybersecurity yet. VICE’s Taylor Wilson meets the scientists at the cutting edge of this new age of computing.

Evading Heisenberg isn’t easy

Posted by in categories: particle physics, quantum physics

EPFL researchers, with colleagues at the University of Cambridge and IBM Research-Zurich, unravel novel dynamics in the interaction between light and mechanical motion with significant implications for quantum measurements designed to evade the influence of the detector in the notorious ‘back action limit’ problem.

The limits of classical measurements of mechanical motion have been pushed beyond expectations in recent years, e.g. in the first direct observation of , which were manifested as tiny displacements of mirrors in kilometer-scale optical interferometers. On the microscopic scale, atomic- and magnetic-resonance force microscopes can now reveal the atomic structure of materials and even sense the spins of single atoms.

But the that we can achieve using purely conventional means is limited. For example, Heisenberg’s uncertainty principle in implies the presence of “measurement backaction”: the exact knowledge of the location of a particle invariably destroys any knowledge of its momentum, and thus of predicting any of its future locations.

Scientists Predict Quantum Jumps, Turning Physics on Its Head

Posted by in categories: computing, quantum physics

In 1935, physicist Erwin Schrödinger concocted a thought experiment to illustrate a pair of strange quantum physics phenomena: superposition and unpredictability.

The experiment became known as Schrödinger’s cat, and for more than 80 years, it’s served as a cornerstone of quantum physics. But in a newly published study, a team of Yale scientists essentially destroys the premise at the center of the experiment — groundbreaking work that could finally allow researchers to develop useful quantum computers.
