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 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 The Schrödinger lecture 2012 - Metamaterials: new horizons in electromagnetism An American Tragedy The election of Donald Trump to the Presidency is nothing less than a tragedy for the American republic, a tragedy for the Constitution, and a triumph for the forces, at home and abroad, of nativism, authoritarianism, misogyny, and racism. Trump’s shocking victory, his ascension to the Presidency, is a sickening event in the history of the United States and liberal democracy. On January 20, 2017, we will bid farewell to the first African-American President—a man of integrity, dignity, and generous spirit—and witness the inauguration of a con who did little to spurn endorsement by forces of xenophobia and white supremacy. It is impossible to react to this moment with anything less than revulsion and profound anxiety. All along, Trump seemed like a twisted caricature of every rotten reflex of the radical right. In the coming days, commentators will attempt to normalize this event.

Computer del futuro: creato il chip che funziona con la luce I computer del futuro? Funzioneranno con la luce. Presso il laboratori del Cnr è nato un micro laboratorio quantistico che usa i fotoni per trasmettere i dati. È solo un piccolo chip di vetro di pochi centimetri ma al tempo stesso è il più piccolo laboratorio in grado di simulare fenomeni fisici quantistici complessi. Il chip è frutto della collaborazione tra i ricercatori del dipartimento di Fisica dell’Università Sapienza di Roma, dell’Istituto di fotonica e nanotecnologie del Consiglio nazionale delle ricerche (Ifn-Cnr) e del Politecnico di Milano. Ma come funziona? Per simulare il comportamento di vari tipi di particelle, i ricercatori hanno ‘costretto’ i fotoni a comportarsi sia come bosoni (la classe a cui appartengono i fotoni) sia come fermioni (la classe di elettroni, protoni, neutroni). Quello appena creato potrebbe rappresentare dunque un nuovo passo verso il processore del futuro, con capacità e velocità di calcolo attualmente impossibili per i computer classici. Leggi anche:
