Researchers prove quantum algorithm works by solving linear equations on a quantum computer
Pendulum swings back on 350-year-old mathematical mystery
(Phys.org) —A 350-year-old mathematical mystery could lead toward a better understanding of medical conditions like epilepsy or even the behavior of predator-prey systems in the wild, University of Pittsburgh researchers ...
Computer simulations shed light on how immune cells identify foreign antigens
How do immune cells manage to sort through vast numbers of similar-looking proteins within the body to detect foreign invaders and fight infections? McGill researchers used computational tools to examine what kind of solutions ...
Tiny bubbles in your metallic glass may not be a cause for celebration
Bubbles in a champagne glass may add a festive fizz to the drink, but microscopic bubbles that form in a material called metallic glass can signal serious trouble. In this normally high-strength material, bubbles may indicate ...
Entanglement in a flash (w/ video)
(Phys.org) —JQI researchers under the direction of Chris Monroe have produced quantum entanglement between a single atom's motion and its spin state thousands of times faster than previously reported, demonstrating unprecedented ...
New principle sets maximum limit on quantum information communication
Cool electron acceleration
Physicists from the Max-Planck-Institute of Quantum Optics produced electron pulses from a laser accelerator whose individual particles all have nearly the same, tuneable energy.
Dense hydrogen in a new light
(Phys.org) —Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich ...
Researchers suggest gas cloud could reveal black holes near center of Milky Way galaxy
Theorists apply loop quantum gravity theory to black hole
Meta-transmitarray offers unprecedented control of light on subwavelength scales
More precision from less predictability: A new quantum trade-off
An important advance in the quantitative understanding and experimental verification of complementarity; arguably the most important foundational principle of quantum mechanics.
Physics team entangles photons that never coexisted in time
Researchers 'light' magnetic fire and analyse how energy propagates
The propagation of the so-called 'magnetic fire' in certain systems seems to be "the only combustion process ruled by quantum laws known in the nature", points out Javier Tejada, Professor of Condensed Matter ...
