Quantum contextuality in d-dimensional systems — •Ali Asadian, Costantino Burdoni, Frank Steinhoff, and Otfried Guehne — Walter-Flex-Straße 3, Siegen, Germany

In a recent work, we proposed a new protocol for performing fundamental tests of quantum mechanics with massive objects. In this approach a single two-level system is used to probe the motion of a mechanical oscillator via multiple Ramsey interference measurements. This scheme enables the measurement of modular variables of macroscopic continuous variable systems and the correlations thereof. Furthermore, we present a general framework based on Weyl-Heisenberg groups for probing quantum contextuality in d-dimensional systems extending to the continuous limit. Experimental implementations of our analysis using the above-mentioned scheme are also discussed.
