Atomic imperfections move quantum communication network closer to reality

Posted by in categories: engineering, quantum physics

An international team led by the University of Chicago’s Institute for Molecular Engineering has discovered how to manipulate a weird quantum interface between light and matter in silicon carbide along wavelengths used in telecommunications.

The work advances the possibility of applying quantum mechanical principles to existing optical fiber networks for secure communications and geographically distributed quantum computation. Prof. David Awschalom and his 13 co-authors announced their discovery in the June 23 issue of Physical Review X.

“Silicon carbide is currently used to build a wide variety of classical electronic devices today,” said Awschalom, the Liew Family Professor in Molecular Engineering at UChicago and a senior scientist at Argonne National Laboratory. “All of the processing protocols are in place to fabricate small quantum devices out of this material. These results offer a pathway for bringing quantum physics into the technological world.”

Scientists Demonstrate “Liquid Light” at Room Temperature for the First Time

Posted by in categories: nanotechnology, quantum physics

Researchers from Italy and Canada have made liquid light at room temperatures for the first time. The work paves the way for studying quantum hydrodynamics further and for future applications of this new type of matter in electronics devices.

Thanks to technological advances, scientists now have various ways of manipulating matter. Often times, these result in discovering new types of matter that posses unique properties — like the famous metallic hydrogen and the bizarre time crystal. The discovery of such materials leads to a wide range of potential applications in electronics. One of these is the so-called “liquid light,” a strange matter which researchers from the CNR NANOTECH Institute of Nanotechnology in Italy and the Polytechnique Montréal in Canada recently formed at room temperature for the first time.

The key to better wireless charging lies in quantum mechanics

Posted by in categories: mobile phones, quantum physics

Wireless charging is a great idea in theory: You can just place your device on a charging mat without having to mess with any wires. But it still doesn’t solve the main hassle of charging in the first place, which is the requirement to leave your device in one place. But now, scientists may have found the answer to that problem using principles from quantum mechanics.

Currently, wireless, or inductive, charging uses an electromagnetic field to transmit energy over very short distances. That’s why your phone, or whatever device you’re charging wirelessly, must remain near a wireless pad in order to actually charge. But Shanhui Fan and his team at Stanford University have published an article in Nature that details a wireless charging system that works even when the charger and device are a meter apart. You can also move around the device while it’s being charged without interrupting the power transfer.

It works by using a principle of quantum mechanics called parity-time symmetry to create a charger with a self-adjusting power flow. A connected amplifier automatically controls the flow of power between the transmitter and receiver. As a device moves further away from the charger, the power levels adjust automatically to ensure an even and uninterrupted flow of current.

China’s Micius satellite sets distance record for quantum entanglement in space

Posted by in categories: encryption, quantum physics, space

Chinese researchers report that they’ve set a new distance record for quantum teleportation through space, the phenomenon that Albert Einstein once scoffed at as “spooky action at a distance.”

The technology isn’t yet ready for prime time, but eventually it could open the way for a new type of unbreakable encryption scheme based on the weirdness of quantum physics.

Faux particles commit physics faux pas

Posted by in categories: cosmology, particle physics, quantum physics

“For example, Hasan says, “we can test theoretical ideas in the early universe,” simulating how particles may have behaved just after the Big Bang, when Lorentz symmetry may not have been obeyed.”

It’s interesting how often I hear condensed matter physicists justify their work by saying “might be important for something with quantum gravity” while condensed matter physics by itself is much more likely than quantum gravity to be good for something.

Quantum Computers and Parallel Universes

Posted by in categories: computing, cosmology, quantum physics

We have a highly respected Theoretical Physicist and a pioneer of Quantum Computing, along with the Founder of one of the leading quantum computer companies, D-Wave (whose clients include Google and NASA), talking about parallel universes. Here is a key that I discovered. They are not talking about parallel universes as a theory but as something factual that exists.


An amazing article on the ability of a Quantum Computer to exploit parallel universes. This article is a MUST READ!
