A Classical-Light Attack on Energy-Time Entangled Quantum Key Distribution, and Countermeasures
... The first discovery of a public-key algorithm was long credited to the groundbreaking work of Diffie and Hellman in 1976 [12], and their algorithm, Diffie-Hellman (DH) key exchange, allows Alice and Bob to exchange a key over an untrusted channel. It would turn out, however, that DH was not the firs ...

Strong Transient Modulation of Horizon Radiation

It is, therefore, plausible that the Unruh effect can also be significantly modulated by variations in a particle detector’s acceleration, i.e., by higher-than-second derivatives in the detector’s trajector ...
