Forty years ago John Wheeler proposed a thought experiment to test the strangest behavior of quantum theory. Now the experiment has been performed between Earth and a satellite in space.
Could the Universe collapse and destroy everything? Probably not.
The Born rule is a fundamental assumption of quantum theory. But could it be wrong?
Quantum teleportation has been achieved over current internet infrastructure.
It turns out that neutrinos aren’t quite as real as you might think.
While we haven’t observed a quantum object as both particle and wave at the same time, new research being hyped as such is very real and very useful.
The Stern-Gerlach effect is strangely counterintuitive, but we can use it to study the magnetic fields of stars.
There’s a story going around the popular press about using quasars to determine whether free will exists. This stems from an MIT press release which talks about using quasars to “close the free will loophole.” Needless to say, the actual paper published in Physical Review Letters isn’t really about free will, but rather about an interesting effect of quantum mechanics. …
Atoms and nuclei are not governed by the familiar rules of Newton but rather by the rules of quantum mechanics. Quantum mechanics can be a bit hard to wrap your head around, but one of the central principles is that you can never be entirely certain of things. If you want to know where an atom is, or what its energy is, you can never get an exact measurement. This “fuzziness” factor leads to a number of strange effects, of which one is quantum tunneling.
