Spooky Alignment of Quasars
New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these ...
متن کاملSpooky Encryption and Its Applications
Consider a setting where inputs x1, . . . , xn are encrypted under independent public keys. Given the ciphertexts {ci = Encpki(xi)}i, Alice outputs ciphertexts c ′ 1, . . . , c ′ n that decrypt to y1, . . . , yn respectively. What relationships between the xi’s and yi’s can Alice induce? Motivated by applications to delegating computations, Dwork, Langberg, Naor, Nissim and Reingold [DLN04] sho...
متن کاملSpooky Dodgeball at a Distance
Spooky Dodgeball at a Distance (or SDAAD for short) is a local multi player electronic game of virtual dodgeball without graphics. Two Players use a Neurosky MindWave headset, a lowcost EEG biosensor, and a PlayStation Move controller to defend and attack in a virtual game of dodgeball. The project is an exploration of the gameplay possibilities that these two different devices could offer when...
متن کاملCounterfactual quantum erasure: spooky action without entanglement
We combine the eyebrow-raising quantum phenomena of erasure and counterfactuality for the first time, proposing a simple yet unusual quantum eraser: A distant Bob can decide to erase which-path information from Alice's photon, dramatically restoring interference-without previously shared entanglement, and without Alice's photon ever leaving her laboratory.
متن کاملSpooky Action at a Temporal Distance
Since the discovery of Bell’s theorem, the physics community has come to take seriously the possibility that the universe might contain physical processes which are spatially nonlocal, but there has been no such revolution with regard to the possibility of temporally nonlocal processes. In this article, we argue that the assumption of temporal locality is actively limiting progress in the field...
