Measurement-induced-nonlocality via the Unruh effect

• Measurement-Induced-Nonlocality (MIN) of both Dirac and Bosonic fields are studied in non-inertial frame beyond the single-mode approximation.
• MIN for Dirac fields persists for any accelerations.
• MIN for Bosonic fields decays to zero in the infinite acceleration limit.
• Dynamic behaviors of the MIN for Dirac fields is quite different from that of Bosonic fields.
• MIN is more general than the quantum nonlocality related to the violation of Bell’s inequalities.

Treated beyond the single-mode approximation, Measurement-Induced-Nonlocality (MIN) is investigated for both Dirac and Bosonic fields in non-inertial frames. Two distinct differences between the Dirac and Bosonic fields are: (i) the MIN for Dirac fields persists for any acceleration, while the quantity for Bosonic fields does decay to zero in the infinite acceleration limit; (ii) the dynamic behaviors of the MIN for Dirac fields is quite different from the Bosonic fields case. Besides, we also study the nonlocality for Dirac fields and find that the MIN is more general than the quantum nonlocality related to violation of Bell’s inequalities. Meanwhile some discussions of geometric discord are presented too.
