New York is known for its food niche stores: The Hummus Place. The Doughnut Plant. The Dumpling Man. Even a spot dedicated solely to rice pudding.
But this week, a store in the East Village went a step further: It sells New York City tap water.
Not just any tap water, insist the owners of Molecule. They say the water streams through a $25,000 filtering machine that uses ultraviolet rays, ozone treatments and reverse osmosis in a seven-stage processing treatment to create what they call pure H20.
“I mean it’s subtle, but if you have a sensitive palate you can totally tell” the difference, said co-owner Adam Ruhf.
Water quality has long been a point of pride for New Yorkers, touted by Mayor Michael Bloomberg as one of the city’s signature distinctions.
Scientists at the Quantum Dynamics division of the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany announced Wednesday that they have built the very first, elementary quantum network comprised of a pair of entangled atoms that transmit information to each other via single photons.
That and a couple of bucks will get you a cup of coffee, plus anything from a perfectly secure data exchange system to the massive scaling via distributed processing of the already mind-bogglingly powerful, if theoretical, potential of a standalone quantum computer.
These are indeed heady days for the pioneers of quantum computing, with each news cycle seemingly bringing forth a major breakthrough in a subatomic frontier that appears poised to revolutionize how our calculating machines deliver us everything from satellite mapping to LOLcats.
Building it was the hardest part:
…had to figure out a means of exercising “perfect control” over all the components in their quantum network, which first meant getting the two atoms that make up the network’s receptor nodes to somehow stay stationary, because a couple of free-floating atoms wouldn’t be able to communicate with the photons relaying information between the two very efficiently.
The team was able to fix their atoms in optical cavities, basically a couple of highly reflective mirrors a short distance from each other, by means of fine-tuned laser beams.
Harnessing the power of supercomputers and their million hours of processing power has allowed some very intriguing physics calculations to take place. One of them is the study of matter in the universe on a subatomic level.
The question, how did we arrive at a universe composed almost exclusively of matter with virtually no antimatter?
The calculation took 54 million processor hours on the IBM BlueGene/P supercomputer at the Argonne National Laboratory in the U.S.
The new research, reported in the March 30 issue of Physical Review Letters, represents an important milestone in understanding kaon decays — which are a fundamental process in physics. It is also inspiring the development of a new generation of supercomputers that will allow the next step in this research.
“It has taken several decades of theoretical developments and the arrival of very powerful supercomputers to enable physicists to control the interactions of the quarks and gluons, the constituents of the elementary particles, with sufficient precision to explore the limits of the standard model and to test new theories,” says Chris Sachrajda, Professor of Physics at the University of Southampton, one of the members of the research team publishing the new findings.
The process by which a kaon decays into two lighter particles known as pions was explored in a 1964 Nobel Prize-winning experiment. This revealed the first experimental evidence of a phenomenon known as charge-parity (CP) violation — a lack of symmetry between particles and their corresponding antiparticles that may explain why the Universe is made of matter, and not antimatter.
