Quantum computing will make your PC look like a graphing calculator

Posted by in categories: computing, education, quantum physics

Winfried Hensinger likes Star Trek. “It goes all the way back to primary school,” said the director of the Sussex Centre for Quantum Technologies in England. “I wanted to be science officer on the Enterprise, so I worked out in about grade five that I wanted to study physics.”

Today, his day-to-day work on abstract notions of quantum mechanics would make even Spock’s ears perk up.

OPINION — Quantum physics provides new world perspective

Posted by in categories: education, mathematics, quantum physics

If I had to pick my least favorite subject in high school, it would be physics.

The concepts themselves were challenging. The math was even more challenging.

However, my views on physics quickly changed when my teacher mentioned the words “quantum mechanics.”

Science breakthrough – light particles teleported across cities

Posted by in categories: particle physics, quantum physics, science, space travel

Scientists have shown they can teleport matter across a city, a development that has been hailed as “a technological breakthrough”.

However, do not expect to see something akin to the Star Trek crew beaming from the planet’s surface to the Starship Enterprise.

Instead, in the two studies, published today in Nature Photonics, separate research groups have used quantum teleportation to send photons to new locations using fibre-optic communications networks in the cities of Hefei in China and Calgary in Canada.

Unbreakable Encryption: Work Has Begun on the World’s First Quantum Enigma Machine

Posted by in categories: encryption, quantum physics

The University of Rochester’s new quantum enigma machine is taking data encryption to a whole new level. This means shorter encryption keys and more difficult message interception.

Need a way to prevent the enemy from intercepting and deciphering your message?

American mathematician Claude Shannon, AKA the “father of information theory” had a way to do it. He came up with a binary system that could transmit messages under three conditions: the key is random, used only once, and is at least as long as the message itself. A long key, though, sounds like a pain.

A tight squeeze for electrons: Quantum effects observed in ‘one-dimensional’ wires

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

Condensing electrons into Quantum Wires to advance QC on multiple devices as well as other areas of technology.


Researchers have observed quantum effects in electrons by squeezing them into one-dimensional ‘quantum wires’ and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.

Scientists have controlled electrons by packing them so tightly that they start to display quantum effects, using an extension of the technology currently used to make computer processors. The technique, reported in the journal Nature Communications, has uncovered properties of quantum matter that could pave a way to new quantum technologies.

For first time, individual atoms seen keeping away from each other or bunching up as pairs

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

Scientists have identified a new method in understanding superconductors, and what one should do to make higher-temperature superconductors even at room temperature. This is certainly a huge deal as we continue to look at ways to build QC machines and devices. Something that my friends at Google should be interested in.


“Learning from this model, we can understand what’s really going on in these superconductors, and what one should do to make higher-temperature superconductors, approaching hopefully room temperature,” says Martin Zwierlein, professor of physics and principal investigator in MIT’s Research Laboratory of Electronics.

If you bottle up a gas and try to image its atoms using today’s most powerful microscopes, you will see little more than a shadowy blur. Atoms zip around at lightning speeds and are difficult to pin down at ambient temperatures.

Levitating nanoparticle improves ‘torque sensing’

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

Researchers have levitated a tiny nanodiamond particle with a laser in a vacuum chamber, using the technique for the first time to detect and measure its “torsional vibration,” an advance that could bring new types of sensors and studies in quantum mechanics.

The experiment represents a nanoscale version of the torsion balance used in the classic Cavendish experiment, performed in 1798 by British scientist Henry Cavendish, which determined Newton’s gravitational constant. A bar balancing two lead spheres at either end was suspended on a thin metal wire. Gravity acting on the two weights caused the wire and bar to twist, and this twisting — or torsion — was measured to calculate the gravitational force.

In the new experiment, an oblong-shaped nanodiamond levitated by a laser beam in a vacuum chamber served the same role as the bar, and the laser beam served the same role as the wire in Cavendish’s experiment.
