Nanoscale neighbors: First use of transformation optics to accurately analyze nonlocality in 3D plasmonic systems
Physicists search for new physics in primordial quantum fluctuations
Qubits that never interact could exhibit past-future entanglement
Maxwell's demon can use quantum information to generate work
Team finds elusive quantum transformations near absolute zero
Heat drives classical phase transitions—think solid, liquid, and gas—but much stranger things can happen when the temperature drops. If phase transitions occur at the coldest temperatures imaginable, ...
Tricking the uncertainty principle
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
Best of Last Week – Popper's experiment realized again, unboiling eggs and the connection between Craigslist and HIV
Does probability come from quantum physics?
(Phys.org)—Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles.
Making Quantum Behavior Observable Using Optical Levitation
What happens when ultracold atomic spins are trapped in an optical lattice structure
Every electrical device, from a simple lightbulb to the latest microchips, is enabled by the movement of electrical charge, or current. The nascent field of 'spintronics' taps into a different electronic ...
Researchers demonstrate Heisenberg uncertainty principle at macro level
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Cosmology: Late news from the Big Bang
Viatcheslav Mukhanov, cosmologist at Ludwig-Maximilians-Universitaet (LMU) in Munich, models the first instants after the creation of our Universe. Data from the Planck telescope have now confirmed beyond ...
Squeezed light produced using silicon micromechanical system
One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as ...
