Researchers demonstrate ‘quantum surrealism’

Posted by in categories: particle physics, quantum physics

Proving Quantum


New research demonstrates that particles at the quantum level can in fact be seen as behaving something like billiard balls rolling along a table, and not merely as the probabilistic smears that the standard interpretation of quantum mechanics suggests. But there’s a catch — the tracks the particles follow do not always behave as one would expect from “realistic” trajectories, but often in a fashion that has been termed “surrealistic.”

In a new version of an old experiment, CIFAR Senior Fellow Aephraim Steinberg (University of Toronto) and colleagues tracked the of photons as the particles traced a path through one of two slits and onto a screen. But the researchers went further, and observed the “nonlocal” influence of another photon that the first photon had been entangled with.

ISRO is developing a nano satellite to monitor suspended particles in polluted Indian cities

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

Nano Satellite could be interesting and even expanded upon especially as we look to expand the usage of Quantum Technology across various wireless devices in the future as well as microbot technology to enable connectivity to the cloud and other wireless devices.


The nano-satellite, which is among ISRO’s important missions, will monitor air pollutants that pollute cities including Delhi, Lucknow, Amritsar and Allahabad.

The nano-satellite will weigh 15kg and placed 500 km above the earth.

Quantum gravity is a theory that has been the target of decades of study by physicists worldwide. If this idea is proven, it would tie together the General Theory of Relativity (which governs gravitational fields) with quantum mechanics, and the bizarro-world of subatomic particles.

Gravitational waves, produced by accelerating objects, ripple through space-time, according to most interpretations of the General Theory of Relativity penned by famed physicist Albert Einstein. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have announced they detected these disturbances in the fabric of time and space for the first time.

Controlling lasers to a millionth of a percent for trapped ion quantum computer

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

Jungsang Kim is trying to create a quantum computer by controlling the frequency of a laser to within a millionth of a percent.

According to David DiVincenzo, a prominent computer scientist at IBM, researchers must meet five criteria to create a true quantum computing device.

First, Kim needs a well-defined system that can represent different states. For example, classical computers use small electrical switches made out of semiconductors to indicate a 1 or a 0. But because an atom’s quantum spin can point in an infinite number of directions, controlling its state with a high degree of reliability is very difficult. Kim’s group has demonstrated this feat with an accuracy on par with anyone in the world.

Could microwaves finally crack quantum computing?

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

Radiation works as a ‘tuning fork’ to control the spin of electrons.

Scientists have found a new way of moving information between quantum bits in a computer. They used a highly purified sample of silicon doped with bismuth atoms (left) before fitting a superconducting aluminium resonator to it (middle and right).

Researchers develop error correction method for quantum computing based on Majorana fermions

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

Theoretical physicists at MIT recently reported a quantum computer design featuring an array of superconducting islands on the surface of a topological insulator. They propose basing both quantum computation and error correction on the peculiar behavior of electrons at neighboring corners of these islands and their ability to interact across islands at a distance. “The lowest energy state of this system is a very highly entangled quantum state, and it is this state that can be used to encode and manipulate qubits,” says graduate student Sagar Vijay, lead co-author of the paper on the proposed system, with senior author Liang Fu, associate professor of physics at MIT, and Timothy H. Hsieh PhD ’15. As Vijay explains it, the proposed system can encode logical qubits that can be read by shining light on them. At the simplest level of explanation, the system can characterize the state of a quantum bit as a zero or a one based on whether there is an odd or even number of electrons associated with a superconducting quantum bit, but the underlying physical interactions that allow this are highly complex.

Toyota’s weird, bright green Prius uses science to stay cooler in the sun

Posted by in categories: economics, particle physics, science, transportation

The Prius is an intentionally odd-looking car that gets odder with every generation; I’m pretty sure even ardent defenders of Toyota’s flagship hybrid could agree with me on that. So why not throw an equally odd paint color on top?

What you’re looking at here is the new Prius in “Thermo-Tect Lime Green,” which is more than your average upsettingly loud paint color. Toyota says that by removing the carbon black particles found in most paint and replacing them with titanium oxide, it has significantly increased the vehicle’s solar reflectivity — in other words, the car heats up less, which lessens the need for air conditioning, which in turn improves fuel economy. And fuel economy, of course, is what the Prius is all about.

White paint also does a good job of keeping the sun’s heat at bay, but Toyota actually says that its Thermo-Tect paint outperformed white in a two-hour summer test outdoors. Basically, this technology means that you might be able to get the color of your choice on your next car and still reduce your AC use. Granted, lime green may not be your first choice, but there doesn’t seem to be anything stopping Toyota from rolling it out to other colors as well.

Graphene is going to change the world — or so we’ve been told.

Since its discovery a decade ago, scientists and tech gurus have hailed graphene as the wonder material that could replace silicon in electronics, increase the efficiency of batteries, the durability and conductivity of touch screens and pave the way for cheap thermal electric energy, among many other things.
