Schrödinger’s cat is both ALIVE AND DEAD!

riNews, Quantum Physics2 Comments

They’ve finally solved it. It’s one of quantum mechanics’ most elusive concepts, ever since Erwin Schrödinger crafted the famous “Schrödinger’s cat” thought experiment. In the current experiment, led by Martin Ringbauer of the University of Queensland, photons seem to genuinely exist in multiple states until they’re measured. There’s still wriggle-room in their result, reported in Nature Physics here (Arxiv pre-print in full here), since … Read More

Quantum Physics may have just gotten simpler

Here’s a nice sur­prise: quan­tum phys­ics is less com­pli­cat­ed than we thought, ac­cord­ing to new re­search. The work links two strange fea­tures of the quan­tum world—or na­ture at the small­est scales, such as that of sub­a­tom­ic par­t­i­cles—call­ing them dif­fer­ent man­i­festa­t­ions of the same thing. Quan­tum phys­ics says that par­t­i­cles can be­have like waves, and vi­ce versa. Re­search­ers have now con­clud­ed … Read More

25km quantum entanglement!

riNews, Quantum Physics5 Comments

Physicists at the University of Geneva (UNIGE) have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometres of optical fibre. The experiment, carried out in the laboratory of Professor Nicolas Gisin, constitutes a first, and simply pulverises the previous recordof 6 kilometres achieved ten years ago by the same UNIGE team. Passing from light into matter, using … Read More

Time travel simulated by Australian physicists

riNews, Quantum Physics6 Comments

Physicists at the University of Queensland in Australia have used photons – single particles of light – to simulate quantum particles travelling through time and study their behaviour. They were hoping to find out more about whether time travel would be possible at the quantum level – a theory first predicted in 1991. In the study, the researchers simulated the … Read More
