The original paper by Kim et al. on the Delayed Choice Quantum Eraser suggests the concept of retrocausality, which stems ...

Classical Physics (Physics established mostly by Newton), has one property that we may think that is universal, which is, certainty. For example, by using the mathematics of Newton, we can precisely ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

An international research group has developed a new X-ray spectroscopy method based on the classical double-slit experiment to gain new insights into the physical properties of solids. An ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...
