I’ve written about the Pew Research Center’s recent study of American attitudes towards future technology. One of the more controversial ideas in the study is teleportation, with only 39% of respondents expecting us to have invented teleportation by 2064. We’ve already invented (or at least discovered) one kind of teleportation: quantum entanglement, which a team of Austrian physicists has recently perfected to 103 dimensions using only two protons. Our growing understanding of entanglement can be really useful in quantum computing, but there’s a big difference between transporting protons and transporting matter, and between transporting individual molecules and transporting systems. And if we ever start trying to transport people, a bigger question emerges. Michio Kaku outlines it here. via Mysterious Universe.
