The sudden change phenomenon of quantum discord
Lucas C. Céleri, Jonas Maziero
Even if the parameters determining a system's state are varied smoothly, the behavior of quantum correlations alike to quantum discord, and of its classical counterparts, can be ve…
Fragile states are better for quantum metrology
Kavan Modi, Lucas C. Céleri, Jayne Thompson +1
In quantum metrology, quantum probe states are capable of estimating unknown physical parameters to precisions beyond classical limits. What qualities do such states possess? Here…
Spin and localization of relativistic fermions and uncertainty relations
Lucas C. Céleri, Vasilis Kiosses, Daniel R. Terno
We discuss relations between several relativistic spin observables and derive a Lorentz-invariant characteristic of a reduced spin density matrix.A relativistic position operator t…
