A non-robust quantum correlation self-test
We show that exact self-testing of a quantum correlation does not imply robust self-testing. Man\v{c}inska and Schmidt previously established such a separation for non-local games, but their obstruction to robustness arises from two distinct optimal correlations, with the self-tested one remaining robust. We establish the separation for a single correlation. Our proof is operator-algebraic. The main technical contribution is a general constructi...

Pulsed coherent and squeezed driving of a spin-$S$ emitter as a deterministic source of Wigner-negative light
Generating propagating Wigner-negative states of light is an important and difficult task for many quantum technologies. Historically, the proposed methods of creating such states have been intrinsically probabilistic, relying on conditional measurements or photon heralding. More recently, methods have been proposed involving the steady-state driving of two-level emitters, where Wigner-negative temporal modes are present in the outgoing field. W...
