The very notion of quantum computing is a bit mind numbing, and the technology is so nascent that researchers aren’t even really sure of the best way to go about constructing a quantum computer. Nonetheless, D-Wave Systems Inc. has just sold one of its eponymous D-Wave One quantum computing systems to none other than Lockheed Martin, along with a multi-year contract to keep the thing working.
Physicists at the University of Geneva in Switzerland have devised a new kind of quantum experiment using humans as photon detectors, and in doing so have made the quantum phenomenon of entanglement visible to the naked eye for the first time.
In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity. The information, in the form of light, was manipulated in such a way that it existed in two states at the same time, and it was destroyed in one spot and recreated in another. The new teleportation breakthrough is a major step toward building safe, effective quantum computers.
One of the most promising materials in science could answer some questions about one of the most elusive particles in the universe, according to a new paper. A trio of Spanish physicists believes that graphene, that simple, special Nobel-winning stuff, could provide some key insights into the behavior of the Higgs boson.
Chemists have messed with the constituent parts of a helium atom and fooled it into behaving like it was hydrogen. This form of alchemy allows a physical test of how atomic mass affects chemical reaction rates.
The trickery involves a particle accelerator, a heavy subatomic particle and some knowledge of quantum mechanics.
Physicists working at the Large Hadron Collider report that after a series of tests, they have not seen any mini black holes, to the chagrin of string theorists and the relief of disaster theorists.
Researchers working on the Compact Muon Solenoid team have been crunching numbers to test a form of string theory that calls for the creation and instant evaporation of miniature black holes. They report that the telltale signs of these black holes are disappointingly absent, however.
If we’re ever going to create the next-gen quantum computers that promise to solve complex and difficult problems at super-fast speeds, first we’ll need to a means to manipulate atoms individually. So researchers from Duke and the University of Wisconsin have figured out how to do exactly that. Collaborators from those universities have demonstrated a laser system that can aim and focus tiny bursts of light onto single atoms without affecting other neighboring particles.
IBM is breathing new life into a quantum computing research division at its Thomas J. Watson Research Center, reports New York Times. The computer giant has hired alumni from promising quantum computing programs at Yale and the University of California-Santa Barbara, both of which made quantum leaps in the past year using standard superconducting material.
For the first time, scientists have been able to watch electrons move in an atom's outer shell, in a breakthrough with major implications for our understanding of chemical processes.
Using ultra-short flashes of laser light, scientists from the Max Planck Institute of Quantum Optics in Germany and Lawrence Berkeley National Laboratory in Berkeley, Calif., were able to time oscillations between valence electrons' quantum states.
The world of quantum mechanics gives us some pretty weird things -- such as matter that exists in all possible places at once, and strange states of matter like supersolids, a phenomenon in which a solid essentially acts like a liquid.
A new research paper brings new meaning to the joke that all science is just physics. A team of scientists at the National University of Singapore suggests that it is quantum entanglement that holds our DNA together.
It's hard to prove, but it would be a potentially explosive finding, as Technology Review explains.
Physicists have long been able to "ghost image" -- that is, to use a split laser beam to detect the presence of an object without actually seeing or interacting with it -- but the process is complicated and can take a while. Now physicists at the University of Rochester's Institute of Optics say they've devised a simpler means to detect the presence of a known object using a single photon.
How many cats have to be both dead and alive before researchers are content that they've entangled enough particles? The current count is now five, but research published today in the Science suggests that it could be many more than that. Perhaps that's bad news for Schrodinger's cat, but it's great news for quantum pursuits like precision imaging and ultra-fast computing.
Scientists have long speculated that birds navigate the globe using magnetism; however, a new study suggests that quantum entanglement indeed enables birds to "see" the Earth's magnetic field as if it were a pattern of colors.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
