Persistence of measurement-induced nonlocality in uniformly accelerating Unruh-DeWitt detectors

Uniform acceleration induces a thermal response to the Minkowski vacuum and can thereby modify quantum correlations. For measurement-induced nonlocality (MIN), a form of nonclassical correlation distinct from entanglement, previous field-mode analyses of bosonic fields found that it decreases with increasing accelerati...

Mode-pairing quantum key distribution with a heralded single-photon source.

Mode-pairing quantum key distribution (MP-QKD) is a promising protocol immune to detector side-channel attacks and capable of breaking the repeaterless PLOB bound without global phase locking. Existing MP-QKD protocols employ weak coherent sources (WCSs) with a low probability of single-photon emission, hindering MP-QK...

Fully passive reference-frame-independent quantum key distribution with finite-key security analysis

Fully passive quantum key distribution (QKD) avoids active modulation of the source and enhances robustness against side-channel attacks. However, existing fully passive QKD systems suffer from low resource efficiency and dependence on precisely calibrated reference frames, limiting their practical applicability. We pr...
