• Abstract: We propose a multisetting protocol for the detection of two-body Bell correlations, and apply it to spin-nematic squeezed states realized in $f$ pairs of SU(2) subsystems within spin-$f$ atomic Bose-Einstein condensates. Experimental data for $f=1$, alongside with numerical simulations using the truncated Wigner method for $f=1,\,2,\,3$, demonstrate the effectiveness of the proposed protocol. Our findings extend the reach of multisetting Bell tests in ultracold atomic system, paving the way for extended quantum information processing in high-spin ensemble platforms.

  A qubit in a high quality superconducting microwave cavity offers the opportunity to perform the first layer of error correction in a single device. We use a 3-wave mixing coupling element to engineer a programmable beamsplitter interaction between two bosonic modes separated by more than an octave in frequency. We then introduce a new protocol to realize a hybrid controlled-SWAP operation in the regime $g_bsapproxchi$, in which a transmon provides the control bit for the SWAP of two bosonic modes.

  We introduce and study an intermediate hybrid no-signaling quantum set of non-local correlations that we term $textbfHNSQ$ in the multi-party Bell scenario. Specifically, the set $textbfHNSQ$ is a super-quantum set of correlations derived from no-signaling assemblages. In contrast to the usual no-signaling correlations, the new set allows for simple security of (one-sided)-device-independent applications against super-quantum adversaries.

  We prove that twist-untwist protocols provide the lowest estimation error among quantum metrology protocols. We consider all-to-all interactions generated by one-axis twisting. We show that the error of a twist-untwist protocol can be decreased by a factor of $L$ without an increase in the noise of spin measurement.
