Witnessing irreducible dimension
Wan Cong, Yu Cai, Jean-Daniel Bancal +1
The Hilbert space dimension of a quantum system is the most basic quantifier of its information content. Lower bounds on the dimension can be certified in a device-independent way,…
A new device-independent dimension witness and its experimental implementation
Yu Cai, Jean-Daniel Bancal, Jacquiline Romero +1
A dimension witness is a criterion that sets a lower bound on the dimension needed to reproduce the observed data. Three types of dimension witnesses can be found in the literature…
Measurement-dependent locality beyond i.i.d
Ernest Y. -Z. Tan, Yu Cai, Valerio Scarani
When conducting a Bell test, it is normal to assume that the preparation of the quantum state is independent of the measurements performed on it. Remarkably, the violation of local…
