Abstracts of Current Research:

  • D. Rohrlich,  Stronger-than-quantum bipartite correlations violate relativistic causality in the classical limit.  Submitted to Phys. Rev. Lett.  Superquantum ("PR-box") correlations, though designed to respect relativistic causality, violate relativistic causality in the classical limit. Generalizing to all stronger-than-quantum bipartite correlations, I derive Tsirelson's bound from the axioms of nonlocality, relativistic causality and the existence of a classical limit. This derivation of Tsirelson's bound does not assume quantum mechanics yet shows how Hilbert space is implicit in quantum correlations.

  • D. Rohrlich, Y. Neiman, Y. Japha and R. Folman, Interference swapping in scattering from a nonlocal quantum target. Phys. Rev. Lett. 96 (2006) 173601: We describe a new and distinctive interferometry in which a probe particle scatters off a superposition of locations of a single free target particle. Probe particles scattering off a single free "mirror" (in one dimension) or a single free "slit" (in two dimensions) can "swap" interference with the superposed target states. The condition for interference is loss of orthogonality of the target states and reduces, in simple examples, to transfer of orthogonality from target to probe states. We analyze experimental parameters and conditions necessary for interference to be observed.

  • S. Popescu and D. Rohrlich, Thermodynamics and the measure of entanglement. Phys. Rev. A56 (1997) Rapid Comm. R3319: We point out formal correspondences between thermodynamics and entanglement. By applying them to previous work, we show that entropy of entanglement is the unique measure of entanglement for pure states.
