A first look inside Google's futuristic quantum lab In May, Google launched the Quantum Artificial Intelligence Lab with hardware from the Canadian quantum computing company D-Wave and technical expertise from NASA. It was an ambitious open research project aimed at exploring both the capabilities of quantum computer architecture and the mysteries of space exploration — but in the months since, they've stayed quiet about exactly what kind of work they've been doing there. Operated at near-absolute-zero temperatures Tomorrow, they're breaking the silence with a brief short film, set to debut at the Imagine Science Films Festival at Google New York. The film takes a look at various researchers working on the project, as well as the computer itself, which has to be operated at near-absolute-zero temperatures. Video provided by Google "We don't know what the best questions are to ask that computer." Related Items nasa quantum computer d-wave quantum artificial intelligence lab Glass Google

Insane Assassin's Creed III concept art by William Wu. New qubit control bodes well for future of quantum computing (Phys.org)—Yale University scientists have found a way to observe quantum information while preserving its integrity, an achievement that offers researchers greater control in the volatile realm of quantum mechanics and greatly improves the prospects of quantum computing. Quantum computers would be exponentially faster than the most powerful computers of today. "Our experiment is a dress rehearsal for a type of process essential for quantum computing," said Michel Devoret, the Frederick William Beinecke Professor of Applied Physics & Physics at Yale and principal investigator of research published Jan. 11 in the journal Science. "What this experiment really allows is an active understanding of quantum mechanics. In quantum systems, microscopic units called qubits represent information. The Yale physicists successfully devised a new, non-destructive measurement system for observing, tracking and documenting all changes in a qubit's state, thus preserving the qubit's informational value.

Graphene: materials in the flatland How Matter Lost Its Mojo You’re sitting here, reading this article. Maybe it’s a hard copy, or an e-book on a tablet computer or e-reader. It doesn’t matter. But what is matter, exactly? Let’s make our question a little more focused. To understand what a cube of ice is made of, we need to draw on the learning acquired by the chemists. The mystery of the combining volumes of hydrogen and oxygen gas to produce water was resolved when it was realized that hydrogen and oxygen are both diatomic gases, H2 and O2. This partly answers our first question. About 99 percent of the masses of the proton and neutron seem to be unaccounted for. It so happens that our cube of ice weighs about 18 grams, which means that it represents a mole of water, more or less. But, of course, we can go further. Hydrogen still has only one (its nucleus consists of a single proton—no neutrons).

icists show self-correcting quantum computers are theoretically possible (Phys.org) —Using exotic components such as color codes, new phases of quantum matter, and extra dimensions, a team of physicists has shown that it's theoretically possible to construct a quantum computer that has the ability to correct itself whenever an error occurs. "The greatest significance of our work is showing that self-correcting quantum computing at a finite temperature is not impossible as a matter of principle," physicist Héctor Bombin told Phys.org. Bombin was at MIT in Cambridge, Massachusetts, while performing the study and is currently at the Perimeter Institute in Waterloo, Ontario. Bombin and his coauthors have published a paper on their proposed self-correcting quantum computer in a recent issue of the New Journal of Physics. Error correction in quantum computers cannot be performed the same way as in classical computers, where information is stored multiple times for redundancy. The first type is bare quantum computers, which do not have any type of error correction.

A Guy Created Hilarious Fake Animal Facts & Put Them Up At The Zoo If you've ever been to a zoo, you know that those little 'blurbs' on the animal signs can often go overlooked. Most people don't care what country the red-tailed hawk originated from or the typical shade of bamboo koalas prefers to snack on at night. Comedian Jeff Wysaski (aka Obvious Plant), decided to spice up those fun facts by making them, well, not facts at all. Check out a handful of his signs below, and for more of his work check him out here. Hyperlink
