Our paper, “Angular Momentum Flows without anything carrying it”, was recently featured in New Scientist, in New spin on quantum theory forces rethink of a fundamental physics law. Then it was featured in Spectrum.de, in New quantum paradox triggers controversy (in German). This was translated into English, appearing in Scientific American as A new Quantum… Continue reading Articles in New Scientist, Scientific American & Spektrum.de

## Conservation Laws For Every Quantum Measurement Outcome

In Quantum Mechanics, a cylinder can simultaneously rotate clockwise and anti-clockwise at the same time. This phenomenon, called superposition, is crucial for paradoxes like SchrÃ¶dinger’s cat, and applications such as Quantum Computing. If we measure which way the cylinder rotates, we will find it to be clockwise or anti-clockwise. This gives us a paradox, as… Continue reading Conservation Laws For Every Quantum Measurement Outcome

## Angular Momentum Flows without anything carrying it

Yakir Aharonov, Sandu Popescu and I have written a new paper where we show how Angular Momentum, a conserved quantity, can travel from one place to another across a region of space which is empty except for a vanishingly small probability of containing a particle. Remarkably, this probability, which can be made as small as… Continue reading Angular Momentum Flows without anything carrying it
