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.

Lockheed Executive Blows Lid Off of Secret Government Space Travel (Quantum Entanglement)

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

Another (more in depth) on Lockheed’s efforts on Space Travel leveraging Quantum Entanglement.


It’s called quantum entanglement, it’s extremely fascinating and counter to what we believe to be the known scientific laws of the universe, so much so that Einstein himself could not wrap his head around it. Although it’s called “quantum entanglement,” though Einstein referred to it as “spooky action at a distance.”

‘Impossible’ Quantum Space Engine That Breaks Laws Of Physics Is About To Be Tested In Space

Posted by in categories: quantum physics, space travel

A couple of years ago, researchers at NASA’s Johnson Space Centre discovered a thruster system which actually generates thrust, despite requiring absolutely no propellant. The implications of this discovery are far-reaching; applications for space flight and other technologies which require propulsion could one day become far cheaper, allowing space exploration to expand exponentially. The existence of this technology also further validates the fact that energy can be derived from tapping into the quantum vacuum, also known as “zero-point.”

Bottom line is that space is not empty, and the energy which lies within it can be used. This was experimentally confirmed when the Casimir Effect illustrated zero point or vacuum state energy, which predicts that two metal plates close together attract each other due to an imbalance in the quantum fluctuations (source)(source).

Google’s Quantum Dream Machine Might Be A Reality Sooner Than You Expected

Posted by in categories: quantum physics, supercomputing, transportation

If all goes according to the plan, tech giant Google might be able to present the world with a phenomenally powerful quantum computer by the end of 2017.

Googler John Martinis and his team of researchers have been working on how quantum computers could be worked out for a long duration of 30 years. And now, it seems, they’re finally on the verge of making the wonder computer a reality. Since the computer would harness the unusual properties of quantum physics that take birth in extreme circumstances like those on the ultra-cold chip, the wonder computer would allow a Google coder to run the calculations he/she requires in a short interval of time like in the duration of a tea/coffee break. This would be quite impressive as the supercomputers of today would take millions of years to run the same calculations. This means, the quantum computer would be able to outperform conventional computers—a concept known as quantum supremacy. But, the Google software, which has been developed on ordinary computers to answer questions or drive cars, is still capable of becoming more intelligent.

Quantum Mechanics Revisited: Physicists Propose New Structure of Time

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

Read a little further into the paper, and things get really weird. If the equations of quantum mechanics must be altered in accordance with the new research, then it will give rise to a new and very curious definition of time.

Time is, essentially, a “crystal”—a highly organized lattice of discrete “particles,” or regularly repeating segments.

One thought on “So, You Want to Program Quantum Computers…”

Posted by in categories: computing, government, quantum physics

Nice article; however, disappointed that the author expanded the exploration of programming in Quantum to include Google, MIT, U. Sydney, etc. who all have been exploring the programming on QC. D-Wave indeed is doing a lot in this space and has been even training numerous US Government personnel on QC; just would be interesting to learn more about the advances in this space from other players who have been sharing for several months their breakthroughs in programming QC.


The jury is still out when it comes to how wide-ranging the application set and market potential for quantum computing will be. Optimistic estimates project that in the 2020s it will be a billion-dollar field, while others expect the novelty will wear off and the one company behind the actual production of quantum annealing machines will go bust.

Ultimately, whichever direction the market goes with quantum computing will depend on two things. First, the ability for applications of sufficient value to warrant the cost of quantum systems have to be in place. Second, and connected to that point, is the fact that enough problems can be mapped to these machines—a tricky problem that if not solved, will lead to a limited ecosystem of capabilities and, of course, developers.

Quantum information encoded in spinning black holes

Posted by in categories: computing, cosmology, quantum physics

Rotating black holes can implement quantum gates and quantum circuits, like Bell states, which are quantum counterparts of the classical computer programing.


The black holes sparked the public imagination for almost 100 years. Their presence in the universe has been debated for long; however, the detection of X-ray radiation coming from the center of the galaxies has put an end to the discussion and undoubtedly proven their existence.

The vast majority, if not all, of the known black holes were unveiled by detecting the X-ray radiation emitted by the stellar material around them. Black holes emit X-ray radiation, light with high energy, due to the extreme gravity in their vicinity. X-ray photons emitted near rotating black holes not only exposed the existence of these phantom-like astrophysical bodies, but also seem to carry hidden quantum messages.

18 Corporations Working On Quantum Computing

Posted by in categories: computing, quantum physics, transportation

Not a complete list — where are al the various joint ventures & start ups that are also in play; however, what about all those Laboratories (Governmental, Universities, and joint venture related labs) such as Los Alamos or ORNL or MIT or USC, and what about all of the governmental agencies (NASA, DoD, etc.), and how about all of those special programs like DARPA. And, this is only the US not to mention what has been happening in China, Australia, Canada, UK, Spain, Germany, Russia, Singapore, etc.

Nice article to use as a starting list only; itmissed many, many other companies, labs, universities, and governments who are really leading most of the progress forward in QC. Some start up to add — Qubitekk, QC Ware, Rigetti Computing to just name 3 off the top of my head. Article is missing a lot in its list.


Google, Microsoft, and Airbus are investing in quantum computing. In all, we identified 18 corporates developing the tech, or partnering with startups like D-Wave to do so, and what they hope to achieve.

Quantum Cosmology and the Evolution of Inflationary Spectra [CL]

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

We illustrate how it is possible to calculate the quantum gravitational effects on the spectra of primordial scalar/tensor perturbations starting from the canonical, Wheeler-De Witt, approach to quantum cosmology. The composite matter-gravity system is analysed through a Born-Oppenheimer approach in which gravitation is associated with the heavy degrees of freedom and matter (here represented by a scalar field) with the light ones. Once the independent degrees of freedom are identified the system is canonically quantised. The differential equation governing the dynamics of the primordial spectra with its quantum-gravitational corrections is then obtained and is applied to diverse inflationary evolutions. Finally, the analytical results are compared to observations through a Monte Carlo Markov Chain technique and an estimate of the free parameters of our approach is finally presented and the results obtained are compared with previous ones.
