(Phys.org)—Researchers have designed a new type of mirror that reflects light in a completely different way than conventional mirrors do. The new mirror, called a chiral meta-mirror, has potential applications for information ...
(Phys.org) —There is, so to speak, uncertainty about uncertainty – that is, over the interpretation of how Heisenberg's uncertainty principle describes the extent of disturbance to one observable when measuring another. ...
(PhysOrg.com) -- Many scientists believe that quantum entanglement is required in order for effective quantum computing. Entanglement takes place when there is a connection that exists between two objects - even when they ...
If you switch a bit in the memory of a computer and then switch it back again, you have restored the original state. There are only two states that can be called "0 and 1."

(Phys.org) —Researchers in Singapore, with assistance from materials scientist Ramamoorthy Ramesh, of the University of California, have succeeded in building a prototype ferroelectric memory device that uses light to read ...
(Phys.org) —Researchers at the Hebrew University of Jerusalem have succeeded in causing entanglement swapping between photons that never coexisted in time. In their paper published in the journal Physical Review Letters, ...
(Phys.org) —Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in ...
