US Government Escalates Push for Post-Quantum Cryptography

Posted by in categories: bitcoin, cybercrime/malcode, encryption, government, information science, privacy, quantum physics

Federal agencies of the US government are expanding their calls for quantum computing resistant encryption methods. In effect, the National Institute of Standards (NIST) recently announced a request for public-key post-quantum algorithms. This action follows warnings from the National Security Agency (NSA) about the risks of potential quantum-based cyberattacks and the NSA’s appeal for developing post-quantum algorithms.

Moreover, in the near future, it might possible for anyone to manipulate the awesome power of quantum computing. The astronomical price of a quantum computer would not be a limitation because, for example, IBM is offering to the general public quantum computing via the cloud.

Researchers grow needle- and thread-like diamonds

Posted by in categories: computing, quantum physics

Excellent breakthrough for technology’s future.


Example of diamond crystallites of different shapes, obtained with the help of the technology, worked out in the Lomonosov Moscow State University. There are electron microscopy images of diamond films’ fragments after their oxidation in the air. The material left after the oxidation is represented by needle-like diamond monocrystals of pyramid shape. Credit: Alexander Obraztsov.

Physicists from the Lomonosov Moscow State University have obtained micrometer-sized diamond crystals in the form of a regular pyramid. In cooperation with co-workers from other Russian and foreign research centers, they have also studied the luminescence and electron emission properties of these diamond crystals. The research results have been published in a series of articles in journals including Scientific Reports.

Uncertain Propulsion Breakthroughs?

Posted by in categories: quantum physics, space travel

Now that the EmDrive has made its way into the peer-reviewed literature, it falls in range of Tau Zero’s network of scientist reviewers. Marc Millis, former head of NASA’s Breakthrough Propulsion Physics project and founding architect of the Tau Zero Foundation, has spent the last two months reviewing the relevant papers. Although he is the primary author of what follows, he has enlisted the help of scientists with expertise in experimental issues, all of whom also contributed to BPP, and all of whom remain active in experimental work. The revisions and insertions of George Hathaway (Hathaway Consulting), Martin Tajmar (Dresden University), Eric Davis (EarthTech) and Jordan Maclay (Quantum Fields, LLC) have been discussed through frequent email exchanges as the final text began to emerge. Next week I’ll also be presenting a supplemental report from George Hathaway. So is EmDrive new physics or the result of experimental error? The answer turns out to be surprisingly complex.

It’s time to weigh in about the controversial EmDrive. I say, controversial, because of its profound implications if genuine, plus the lack of enough information with which to determine if it is genuine. A peer-reviewed article about experimental tests of an EmDrive was just published in the AIAA Journal of Propulsion and Power by Harold (Sonny) White and colleagues: White, H., March, P., Lawrence, J., Vera, J., Sylvester, A., Brady, D., & Bailey, P. (2016), “Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum,” Journal of Propulsion and Power, (print version pending, online version here.

MIT Researchers Measure the Quantum Universe –“From the Planck Scale to Life”

Posted by in category: quantum physics

“We know that very small things act quantum, but then big things like you and me don’t act very quantum,” says William Burton, with the MIT physics department. “So we can see how far apart we can stretch a quantum system and still have it act coherently when we bring it back together.”

Testing Predictions of the Quantum Landscape Multiverse 2: The Exponential Inflationary Potential [CEA]

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

The 2015 Planck data release tightened the region of the allowed inflationary models. Inflationary models with convex potentials have now been ruled out since they produce a large tensor to scalar ratio. Meanwhile the same data offers interesting hints on possible deviations from the standard picture of CMB perturbations. Here we revisit the predictions of the theory of the origin of the universe from the landscape multiverse for the case of exponential inflation, for two reasons: firstly to check the status of the anomalies associated with this theory, in the light of the recent Planck data; secondly, to search for a counterexample whereby new physics modifications may bring convex inflationary potentials, thought to have been ruled out, back into the region of potentials allowed by data. Using the exponential inflation as an example of convex potentials, we find that the answer to both tests is positive: modifications to the perturbation spectrum and to the Newtonian potential of the universe originating from the quantum entanglement, bring the exponential potential, back within the allowed region of current data; and, the series of anomalies previously predicted in this theory, is still in good agreement with current data. Hence our finding for this convex potential comes at the price of allowing for additional thermal relic particles, equivalently dark radiation, in the early universe.

Creating tunable terahertz radiation.


Indium arsenide quantum dots in gallium arsenide wafers offer wider pump-wavelength range, significantly higher thermal tolerance, and higher conversion efficiency than typical terahertz radiation sources.
