David Voss at APS Physics writes: ''Nonlocality—the entanglement of one object with another at a distance—is a powerful way to achieve quantum information processing. However, quantum mechanics is tethered by a “no-signaling” principle, that is, these correlations cannot be used to transmit information arbitrarily quickly from one point to another.

We study the noise correlations of one-dimensional binary Bose mixtures, as a probe of their quantum phases. In previous work, we found a rich structure of many-body phases in such mixtures, such as paired and counterflow superfluidity. Here we investigate the signature of these phases in the noise correlations of the atomic cloud after time-of-flight expansion, using both Luttinger liquid theory and the time-evolving block decimation (TEBD) method. We find that paired and counterflow superfluidity exhibit distinctive features in the noise spectra.
