The results of the study published in Physical Review Letters provide the first example of long-distance communication between two quantum optical antennas in analogy to the 19th century experiments of Hertz and Marconi with radio antennas. In those early efforts, dipolar oscillators were used as transmitting and receiving antennas. In the current experiment, two single molecules mimic that scenario at optical frequencies and via a nonclassical optical channel, namely a single-photon stream. This opens many doors for further exciting experiments in which single photons act as carriers of quantum information to be processed by single emitters.

NPL: One step closer to a new kilogram

Revealed on Sunday in the academic journal Nature Nanotechnology, the research is part of a decade-long effort at the University of New South Wales to deliver a quantum computer — a machine that would use the seemingly magical properties of very small particles to instantly perform calculations beyond the scope of today’s classical computers.

...the New South Wales team — lead by professor Michelle Simmons — advanced the cause by demonstrating that Ohm’s Law of electrical resistivity extends to the world of very small particles, and now, together with Gerhard Klimeck and his team at Purdue, they’ve made a more significant breakthrough by placing a single-atom transistor exactly where they want to place it.

Africa is quietly undergoing a tech revolution that could transform the continent. CNN's African Voices has highlighted 10 leading tech voices from different African countries. Each one comments on the role technology plays in boosting entrepreneurship and empowering communities in Africa.

This statement received some criticism in scientific circles. Not because it’s wrong, because it isn’t; without this behavior, we wouldn’t be able to explain the bonds that hold molecules together. The problem is that it sounds like woo woo, and quantum theory attracts woo-woo merde-merchants like the pronouncements of New Age mystics attract flies – metaphorically speaking.

I've long championed what I like to term "conversational physics concepts," as well as diversity on this blog, particularly gender ascendancy in science, technology, engineering and math. Thus, my concentration this month wasn't all physics (though, I'm admittedly partial). For the nation to advance in the future, we need every one of us.

It is my hope one or several posts during the month informed, entertained and inspired. I started these posts with something that struck me as wrong: that due to someone's name and attending a historically black college and university as an undergrad, they would most likely not get a grant from the National Institute of Health. It affected me because I know and have taught one such young man that in his future, this impediment will affect him: he currently attends Howard University in Biology Pre Med, and plans to research in Ear, Nose and Throat ailments. Something that because of my own struggles with Sinusitis, I sincerely HOPE he's successful in getting research dollars!

I post this as a father, with two young men with dreams, hopes and futures in medicine (USARMY) and Civil Engineering. I have watched over Robert and Mildred Goodwin'sgrandsons. As they did for me, I hope and work for a future that they can contribute to positively.

It's a leap year, and my hope is that teachers, professors...and students have found something of themselves in these postings. (Shout out to the students and teachers at Manor High School )

For students, your futures lie not just in sports or rap music; a future in science, technology, engineering and math is not only possible: it is "what you can do for your country" (John F. Kennedy)...and for yourselves.

Sikivie and colleagues point out that axions can form a Bose–Einstein condensate (BEC). Such condensates contain particles that have all fallen into their lowest energy state, and are best known to occur in low-density gases at temperatures close to absolute zero. But since the critical temperature for transition to a BEC depends on density, say the Florida researchers, particles can form BECs at higher temperatures as long as they are dense enough. Even in the primordial heat of the Big Bang, the researchers say, axions would easily be dense enough to form a BEC.

"As a young Black girl in high school, no one ever told me that math was hard or that science was for boys," Dr. Thomas says.

She continued her education at Howard University, receiving a B.Sc. in zoology in 1965, and went on to earn an M.Sc. in microbiology from American University in 1971. She returned to Howard in 1973, as a divorced mother of two, to earn a Ph.D. in cell biology, just in time to join the emerging technology revolution.

Dr. Thomas joined MITRE in the 1970s and rose through the ranks through a combination of skill and willingness to soar. She spent the vast majority of her career at The MITRE Corporation and Mitretek Systems, where she shaped programs that were the beacon for the nation in energy, environment, public safety, health, and national security.
