D.
Rohrlich, Strongerthanquantum bipartite correlations violate relativistic causality in the classical limit. [Submitted to Phys. Rev. Lett.] Superquantum ("PRbox") correlations, though designed to respect relativistic causality, violate relativistic causality in the classical limit. Generalizing to all strongerthanquantum 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.

Y. Aharonov, S. Popescu, D. Rohrlich and P. Skrzypczyk, Quantum Cheshire Cats. [New J. Phys., to appear]
In this paper we present a quantum Cheshire Cat. In a pre
and postselected experiment we find the Cat in one place, and its grin
in another. The Cat is a photon, while the grin is its circular
polarization.

Rohrlich, A
paradox of nonlocal energy conservation. [In preparation] A
superposition of lowenergy photon eigenstates may oscillate, in some
region, at a frequency corresponding to a much higherenergy photon.
Relativistic causality then implies that a detector in that
region, at that time, may find a highenergy photon there. The
resolution of this paradox involves both weak values and modular
variables.
