A similar gap appears when considering quantum versus general nonsignalling correlations: there exist correlations that, despite being compatible with the no-signalling principle, cannot be obtained by performing local measurements on any quantum system [2]. In particular, th ...

Quantum Operating Systems - Henry Corrigan
... The last few years have seen tremendous progress towards the construction of non-trivial quantum computers [7, 23, 29]. A number of start-ups are working towards commercializing the technology, NIST is standardizing new “post-quantum” cryptosystems [41], and industry giants, including Google [20] an ...

Both models can be mapped onto a system of non-interacting fermions, where the equal-position correlation functions are calculated by the Pfaffian method utilizing the theory of Töplitz determinants. In this letter we consider —for the first time— the critical dynam ...
