“ We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.”

@brutalistu Nu prea cred. Daca lumina devine materie, atunci nu va mai prezenta caracteristicile fotonilor, asadar nu va mai produce lumina cum sugereaza imaginea.

Scientists Report Finding Reliable Way to Teleport Data

Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”

In a paper published on Thursday in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.

Quantum teleportation is not the “Star Trek”-style movement of people or things; rather, it involves transferring so-called quantum information — in this case what is known as the spin state of an electron — from one place to another without moving the physical matter to which the information is attached.

Classical bits, the basic units of information in computing, can have only one of two values — either 0 or 1. But quantum bits, or qubits, can simultaneously describe many values. They hold out both the possibility of a new generation of faster computing systems and the ability to create completely secure communication networks.

Reminds me of quantum tunneling. Defapt, pe principiul asta s-ar baza, cred (nu pot vedea decat abstractul jurnalului, deci nu bag mana-n foc; mai ales cand am cunostinte limitate in cuantica).

Something feels fishy...
Doar 33% dintre judecatori au fost convinsi iar "The Royal Society of London for Improving Natural Knowledge" nu este o platforma de peer review, ci o asociatie non-profit. Astept mai multe informatii decat o declaratie.

Sa nu fii om cu cainele ca si cainele va fi om cu tine.
