We examine the effect of the stress tensor of a quantum matter field, such as the electromagnetic field, on the spectrum of primordial gravity waves expected in inflationary cosmology. We find that the net effect is a small reduction in the power spectrum, especially at higher frequencies, but which has a different form from that described by the usual spectral index. Thus this effect has a characteristic signature, and is in principle observable. The net effect is a sum of two contributions, one of which is due to quantum fluctuations of the matter field stress tensor. The other is a quantum correction to the graviton field due to coupling to the expectation value of this stress tensor. Both contributions are sensitive to initial conditions in the very early universe, so this effect has the potential to act as a probe of these initial conditions.

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.

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.

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.

“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.”
