A Bizarre Physics Law Is Making Superfluid Helium Behave Like an Actual Black Hole

Posted by in categories: cosmology, quantum physics

Of all the laws of physics, this is arguably one of the strangest — scientists have discovered that the forces controlling the behaviour of a black hole’s event horizon are also at play in superfluid helium, an extraordinary liquid that flows without friction.

This entanglement area law has now been observed at both the vast scale of black holes and the atomic scale of cold helium, and could be the key to finally establishing the long sought-after quantum theory of gravity — the solution to one of the deepest problems in theoretical physics today.

How to teleport Schrödinger’s cat: this video presents the full quantum teleportation procedure, in which an arbitrary qubit (spin, etc) is teleported from Alice to Bob by way of a pair of particles entangled in a bell (EPR) state and the transmission of information via a classical channel.

Why String Theory Could Be the Key to Uncovering the ‘Theory of Everything’

Posted by in categories: cosmology, quantum physics

A central goal that modern physicists share is finding a single theory that can explain the entire Universe and unite the forces of nature.

The standard model, for example, leaves dark matter, dark energy, and even gravity out of the picture — meaning that it really only accounts for a very small percentage of what makes up the Universe.

Electrons Have Been Caught Disappearing and Reappearing Between Atomic Layers

Posted by in categories: materials, quantum physics

Scientist have spotted a strange type of quantum movement occurring in electrons travelling between the atomic layers of a material.

Instead of travelling from the top to the bottom layer through the middle, the electrons were caught disappearing from the top layer and reappearing in the bottom letter a fraction of a second later — with no trace of them existing in between.

“Electrons can show up on the first floor, then the third floor, without ever having been on the second floor,” said lead researcher Hui Zhao from the University of Kansas.

What if Quantum Computers Used Hard Drives Made of DNA?

Posted by in categories: biotech/medical, computing, quantum physics

You can’t save data on a quantum computer. So a commercial one will need to use vintage tech—ultra dense hard drives, maybe made of DNA or single atoms.

Unveils roadmap for commercial “IBM Q” quantum systems

Posted by in categories: biotech/medical, chemistry, computing, quantum physics

Yorktown Heights, N.Y. — 06 Mar 2017: IBM (NYSE: IBM) announced today an industry-first initiative to build commercially available universal quantum computing systems. “IBM Q” quantum systems and services will be delivered via the IBM Cloud platform. While technologies that currently run on classical computers, such as Watson, can help find patterns and insights buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be seen because the data doesn’t exist and the possibilities that you need to explore to get to the answer are too enormous to ever be processed by classical computers.

IBM Quantum Computing Scientists Hanhee Paik (left) and Sarah Sheldon (right) examine the hardware inside an open dilution fridge at the IBM Q Lab at IBM’s T. J. Watson Research Center in Yorktown, NY. On Monday, March 6, IBM announced that it will build commercially available universal quantum computing systems. IBM Q quantum systems and services will be delivered via the IBM Cloud platform and will be designed to tackle problems that are too complex and exponential in nature for classical computing systems to handle. One of the first and most promising applications for quantum computing will be in the area of chemistry and could lead to the discovery of new medicines and materials. IBM aims at constructing commercial IBM Q systems with ~50 qubits in the next few years to demonstrate capabilities beyond today’s classical systems, and plans to collaborate with key industry partners to develop applications that exploit the quantum speedup of the systems.

Does quantum theory explain consciousness? Take the test to find out

Posted by in categories: computing, neuroscience, quantum physics

A chess problem could help scientists finally unravel whether quantum theory can explain human consciousness.

Oxford professor Sir Roger Penrose created the puzzle to prove the human mind can never be matched by a computer because it exhibits quantum effects.

This means the brain doesn’t follow the rules for the classical properties of matter like a computer.
