China to combat hackers with launch of quantum communication satellite
Posted by Karen Hurst in categories: cybercrime/malcode, quantum physics
Although this states it is to protect China; who will protect us from China’s hacks when they have this.
China is expected to launch the satellite into space in July.

Top international award for UNSW Australia quantum computing chief
Posted by Karen Hurst in categories: computing, electronics, nanotechnology, quantum physics
Love this; Congrats to Michelle Simmons and her work on QC — Superstar females in STEM.
For her world-leading research in the fabrication of atomic-scale devices for quantum computing, UNSW Australia’s Scientia Professor Michelle Simmons has been awarded a prestigious Foresight Institute Feynman Prize in Nanotechnology.
Two international Feynman prizes, named in honour of the late Nobel Prize winning American physicist Richard Feynman, are awarded each year in the categories of theory and experiment to researchers whose work has most advanced Feynman’s nanotechnology goal of molecular manufacturing.

New evidence could break the standard view of quantum mechanics
Posted by Andreas Matt in categories: particle physics, quantum physics
Quantum mechanics is difficult to understand at the best of times, but new evidence suggests that the current standard view of how particles behave on the quantum scale could be very, very wrong.
In fact, the experiment hints that an alternative view predicted almost a century ago might have been right this whole time. And before you get too bummed about that, the good news is that, if confirmed, it would actually make quantum mechanics a whole lot simpler to understand.
So let’s step back for a second here and break this down. First thing’s first, this is just one study, and A LOT more replication and verification would be needed before the standard view comes crumbling down. So don’t go burning any text books just yet, okay? Good.

Samsung Electronics To Skip OLED TV And Go Straight To QLED TV
Posted by Karen Hurst in categories: electronics, quantum physics
Establishing the trend. Q-dot technology will be in all displays soon.
“Samsung Electronics will skip commercializing OLED for TVs and ho straight to QLED technology, perhaps as soon as 2009. Its strategy is to continue to develop its quantum-dot TVs, which are its current major products, and prepare to commercialize QLED technologies during this time.”

Supercrystals with new architecture can enhance drug synthesis
Posted by Karen Hurst in category: quantum physics
Scientists from ITMO University and Trinity College have designed an optically active nanosized supercrystal whose novel architecture can help separate organic molecules, thus considerably facilitating the technology of drug synthesis. The study was published in Scientific Reports (“Chiral quantum supercrystals with total dissymmetry of optical response”).

Viewpoint: An Arrested Implosion
Posted by Karen Hurst in categories: cosmology, particle physics, quantum physics
The collapse of a trapped ultracold magnetic gas is arrested by quantum fluctuations, creating quantum droplets of superfluid atoms.
Macroscopic implosions of quantum matter waves have now been halted by quantum fluctuations. The quantum wave in question is an atomic Bose-Einstein condensate (BEC), a quantum state with thousands to tens of millions of atoms in an ultracold gas all sharing the same macroscopic wave function. Attractive atomic interactions can cause BECs to collapse in spectacular ways, in what’s been termed a “bosenova,” a lighthearted allusion to a supernova explosion [1]. Tilman Pfau and colleagues from the University of Stuttgart, Germany, have shown that for BECs made of dysprosium, whose bosonic isotopes are among the most magnetic atoms in the periodic table, long-range dipole-dipole interactions between these neutral atoms create a totally new phenomenon: the arrested collapse of a quantum magnetic fluid, called a quantum ferrofluid [2, 3]. Such a ferrofluid relies crucially on the strong dipolar interactions in the dysprosium gas.

New method to control quantum systems
Posted by Karen Hurst in categories: computing, electronics, quantum physics
Yesterday, we saw the news from D-Wave in development & release of a new scalable QC. Now, Dartmouth has been able to develop a method to design faster pulses, offering a new way to accurately control quantum systems.
Dartmouth College researchers have discovered a method to design faster pulses, offering a new way to accurately control quantum systems.
The findings appear in the journal Physical Review A.
Quantum physics defines the rules that govern the realm of the ultra-small — the atomic and sub-atomic world — which explains the behavior of matter and its interactions. Scientists have been trying to exploit the seemingly strange properties of this quantum world to build practical devices, such as ultra-fast computers or ultra-precise quantum sensors. Building a practical device, however, requires accurately controlling your device to make it do what you want. This turns out to be challenging since quantum properties are very fragile.
