Latest Delayed choice quantum eraser Stories
Imagine you order a delivery of several glass vases in different colors. Each vase is sent as a separate parcel. What would you think of the courier if the parcels arrive apparently undamaged, yet when you open them, it turns out that all the red vases are intact and all the green ones are smashed to pieces?
Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and therefore on the type of measurement performed.
Researchers have changed one of the most basic rules of quantum mechanics.
Quantum computers are computers that exploit the weird properties of matter at extremely small scales.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated* for the first time the conversion of near-infrared 1,300 nm wavelength single photons emitted from a true quantum source, a semiconductor quantum dot, to a near-visible wavelength of 710 nm.
A team of European scientists has proved conclusively that photons remain entangled over a distance of 144 kilometers, through the atmosphere and into space.
