Har lige læst denne artikel om forskernes successrige forsøg med tidskapsler (underforstået: tids-beskeder, dvs. beskeder som sendes igennem tid og rum og fuldstændigt ødelægger vores normale forståelse af rumtid, det er svært at forklare i Twitter-sætninger, I må hellere læse artiklen selv)... og jeg sidder tilbage med en følelse af at hele universet "konspirerer" (i mangel af bedre ord) imod forskerne...
Vi ved at "noget" holder "noget" skjul. Og vi ved ikke hvad der holder hvad skjult.
Altså, iflg. forskerne.
Hvad forskerne har fundet, kan bedst beskrives billedligt i denne tegning:
The strangeness comes through in an experiment conceived by Robert Spekkens, a physicist who studies the foundations of quantum mechanics at the Perimeter Institute for Theoretical Physics in Waterloo, Canada. Spekkens and his colleagues carried out the experiment in 2009. Alice prepares a photon in one of four possible ways. Classically, we could think of these four ways as two bits of information. Bob then measures the particle in one of two possible ways. If he chooses to measure the particle in the first way, he obtains Alice’s first bit of information; if he chooses the second, he obtains her second bit. (Technically, he does not get either bit with certainty, just with a high degree of probability.) The obvious explanation for this result would be if the photon stores both bits and releases one based on Bob’s choice. But if that were the case, you’d expect Bob to be able to obtain information about both bits — to measure both of them or at least some characteristic of both, such as whether they are the same or different. But he can’t. No experiment, even in principle, can get at both bits — a restriction known as the Holevo bound. “Quantum systems seem to have more memory, but you can’t actually access it,” said Costantino Budroni, a physicist at the University of Siegen in Germany.
