A switch for light wave electronics

Posted by in categories: computing, electronics, quantum physics

Light waves might be able to drive future transistors. The electromagnetic waves of light oscillate approximately one million times in a billionth of a second, hence with petahertz frequencies. In principle also future electronics could reach this speed and become 100.000 times faster than current digital electronics. This requires a better understanding of the sub-atomic electron motion induced by the ultrafast electric field of light. Now a team of the Laboratory for Attosecond Physics (LAP) at the Max-Planck Institute of Quantum Optics (MPQ) and the Ludwig-Maximilians-Universität (LMU) and theorists from the University of Tsukuba combined novel experimental and theoretical techniques which provide direct access to this motion for the first time.

Electron movements form the basis of electronics as they facilitate the storage, processing and transfer of information. State-of-the-art electronic circuits have reached their maximum clock rates at some billion switching cycles per second as they are limited by the heat accumulating in the process of switching power on and off.

The electric field of light changes its direction a trillion times per second and is able to move electrons in solids at this speed. This means that light waves can form the basis for future electronic switching if the induced electron motion and its influence on heat accumulation is precisely understood. Physicists from the Laboratory for Attosecond Physics at the MPQ and the LMU already found out that it is possible to manipulate the electronic properties of matter at optical frequencies.

Richard Feynman: The Quantum Man

Posted by in categories: business, education, habitats, neuroscience, quantum physics

Inspirational bio of the “Quantum Man” Richard Feynman.


Richard Feynman was a Nobel prize-winning physicist whose contemporaries thought that he had the finest brain in physics. He was born on May 11, 1918, in Manhattan and grew up in Far Rockaway, N.Y., a section of Queens, on the Rockaway peninsula.

His parents were non-observant Ashkenazi Jews. His father, Melville Feynman, was a uniform salesman. Nevertheless, he tried to stimulate Richard to have an interest in science at an early age. Melville was the son of Lithuanian Jews who lived in Minsk and emigrated to the U.S. in 1895 when Melville was 5 years old. Although Melville wanted to become a doctor, the family could not afford to support his education. He tried a variety of occupations and finally settled in the uniform business.

China to Launch World’s First Quantum Space Satellite in July

Posted by in categories: government, quantum physics, space

Enough said; China officially makes Quantum communications available via Satellite in July. Now, what does this mean to government funded hackers and the US and Europe?


The launch of the world’s first quantum space satellite developed by China is scheduled for July, according to the project’s chief scientist Pan Jianwei.

BEIJING (Sputnik) — According to the physicist, cited by the People’s Daily Online, the quantum network will connect Beijing, Jinan, Hefei and Shanghai among other cities spanning a 2,000-kilometer (1,243 miles) area.

New Evidence Could Overthrow the Standard View of Quantum Mechanics

Posted by in category: quantum physics

An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that avoids the most baffling features of the subatomic universe.

Computing a secret, unbreakable key

Posted by in categories: computing, quantum physics, security

Awesome.


What once took months by some of the world’s leading scientists can now be done in seconds by undergraduate students thanks to software developed at the University of Waterloo’s Institute for Quantum Computing, paving the way for fast, secure quantum communication.

Researchers at the Institute for Quantum Computing (IQC) at the University of Waterloo developed the first available software to evaluate the security of any protocol for Quantum Key Distribution (QKD).

New device steps toward isolating single electrons for quantum computing

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

Finally, some well deserved recogonition to Argonne Natl. Labs in their efforts on QC with the Univ. Of Chicago.


If biochemists had access to a quantum computer, they could perfectly simulate the properties of new molecules to develop novel drugs in ways that would take the fastest existing computers decades.

Electrons represent an ideal quantum bit, with a “spin” that when pointing up can represent a 0 and down can represent a 1. Such bits are small—even smaller than an atom—and because they do not interact strongly, they can remain quantum for long periods. However, exploiting electrons as qubits also poses a challenge because they must be trapped and manipulated. Which is exactly what David Schuster, assistant professor of physics, and his collaborators at UChicago, Argonne National Laboratory and Yale University have done.

With Moore’s Law in doubt, eyes turn to quantum computing

Posted by in categories: computing, quantum physics

Moore’s Law was already identified as a problem regardless of Quantum. And, the move to Quantum happened regardless of Moores Law and the excitment around QC was not the result of Moores Law limitations. Just like all things, we evolve to better level of maturity.


The chip industry is giving another sign that Moore’s Law is coming to an end, but IBM is offering a glimpse at what might be computing’s future.

Industry experts from around the world who have been working together for years for forecast technology advances in the tech industry are throwing in the towel.
