Researchers explore quantum entanglement
Albert Einstein called quantum entanglement—two particles in different locations, even on other sides of the universe, influencing each other—"spooky action at a distance."
Calculating quantum vacuum forces in nanostructures
(Phys.org)—One of the surprising predictions of quantum mechanics is that uncharged conductors can attract each other over small distances, even in empty space. While the resulting "Casimir force" has been accurately measured ...
Into the quantum internet at the speed of light
Not only do optical fibers transmit information every day around the world at the speed of light, but they can also be harnessed for the transport of quantum information. In the current issue of Nature Ph ...
Improved quantum-dot performance: Could enable more efficient computer displays, enhanced biomedical testing
Quantum dots—tiny particles that emit light in a dazzling array of glowing colors—have the potential for many applications, but have faced a series of hurdles to improved performance. But an MIT team ...
Quantum microscope for living biology
(Phys.org)—A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells.
Physics researchers join effort to finally complete quantum theory
An assistant professor of physics at Indiana University-Purdue University Indianapolis (IUPUI) will be among a team of international researchers looking to advance the theory of quantum mechanics, a notion challenged by Albert ...
Listening to electrons: New method brings scaling-up quantum devices one step closer
(Phys.org)—We're now one step closer to quantum computing becoming a reality thanks to research led by a team of University of Sydney physicists, who have found a new way to detect changes in charges smaller ...
Quantum strategies fail to improve capacity of quantum optical communication channels
Reconcilable differences: Study uncovers the common ground of scientific opposites
(Phys.org)—Searching for common elements in seemingly incompatible scientific theories may lead to the discovery of new ones that revolutionize our understanding of the world.
You don't exist in an infinite number of places, say scientists
Never mind the noise: Quantum entanglement allows channel information rate to exceed Shannon zero-error capacity
Survey shows physicists can't agree on fundamental questions about quantum mechanics
Multiple steps toward the 'quantum singularity'
In early 2011, a pair of theoretical computer scientists at MIT proposed an optical experiment that would harness the weird laws of quantum mechanics to perform a computation impossible on conventional co ...
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 ...
