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.
A new type of circuit involving a whirling donut of supercold gas could lead to the world's first "atomtronic" devices, potentially more powerful than electronics or spintronics, researchers say.
It probably won't be powering your next smart phone, however — it involves laser beams and supercold temperatures a few billionths of a degree above absolute zero.
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.
Ramped-up research efforts at IBM and other labs in the U.S. and Europe could lead to more powerful and more prevalent quantum computers in the near future.
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.
