Quantum computing is getting closer

Posted by in categories: encryption, information science, quantum physics, supercomputing

Electronic computer technology has moved from valves to transistors to progressively more complex integrated circuits and processor designs, with each change bringing higher levels of performance. Now the advent of quantum computers promises a huge step increase in processor performance to solve certain types of problems.

Quantum computers are much faster than the world’s fastest supercomputers for some applications. In 1994 Peter Shor, an applied mathematician at Bell Laboratories, gave the encryption world a shock when he demonstrated an algorithm showing that quantum computers could threaten conventional prime number based encryption methods.

If an adversary conducts successful espionage raids on encrypted information stored in present technology computer installations, possibly through a compromised or issue-motivated individual who transfers it to portable media, it could become vulnerable to decryption by that rival’s quantum computers.

Warning Shots Fired: China Releases Video of Missile Launch, Amps Up Tensions with U.S

Posted by in categories: internet, quantum physics, satellites

China and the US; tensions are mounting and China’s new Quantum Satellite is aiding more fuel to the flames.


By: James Holbrooks (UndergroundReporter) Beijing — Only days after completing production of the largest amphibious aircraft ever built, China has just revealed plans to launch the world’s first satellite designed to conduct quantum experiments in space — a move that could one day lead to a highly secure “orbital internet.”

Assuming the initial satellite performs well, as many as 20 additional craft would follow in the effort to create a new category of communications network. Chinese researchers believe their work could ignite a space race as other nations move to refine the technology.

Viewpoint: Liquid Light with a Whirl

Posted by in category: quantum physics

An elliptical light beam in a nonlinear optical medium pumped by “twisted light” can rotate like an electron around a magnetic field.

Magnetism and rotation have a lot in common. The effect of a magnetic field on a moving charge, the Lorentz force, is formally equivalent to the fictitious force felt by a moving mass in a rotating reference frame, the Coriolis force. For this reason, atomic quantum gases under rotation can be used as quantum simulators of exotic magnetic phenomena for electrons, such as the fractional quantum Hall effect. But there is no direct equivalent of magnetism for photons, which are massless and chargeless. Now, Niclas Westerberg and co-workers at Heriot-Watt University, UK, have shown how to make synthetic magnetic fields for light [1]. They developed a theory that predicts how a light beam in a nonlinear optical medium pumped by “twisted light” will rotate as it propagates, just as an electron will whirl around in a magnetic field. More than that, the light will expand as it goes, demonstrating fluid-like behavior.

How Quantum Mechanics Is Changing Everything We Know About Our Lives

Posted by in categories: neuroscience, quantum physics, time travel

Quantum physics is the new physics that is pointing to something far greater than the materialistic world that we once believed to be the basis of our existence. Not only is it disproving our original perception of space and time, but it is opening the doors to the possibility of time travel, telepathy, and consciousness creating our reality.

Researchers apply quantum theory and Einstein’s special relativity to plasma physics issues

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

Among the intriguing issues in plasma physics are those surrounding X-ray pulsars—collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the sky. Physicists want to know the strength of the magnetic field and density of the plasma that surrounds these pulsars, which can be millions of times greater than the density of plasma in stars like the sun.

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a theory of waves that can infer these properties in greater detail than in standard approaches. The new research analyzes the plasma surrounding the pulsar by coupling Einstein’s theory of relativity with , which describes the motion of subatomic particles such as the atomic nuclei—or ions—and electrons in plasma. Supporting this work is the DOE Office of Science.
