... Definition 2 (Relativistic computer). A relativistic computer in a MalamentHogarth spacetime hM, gab i is a triple hγp , γ, qi such that γ is an upwardinfinite future-directed curve fully in J − (q) of some event q ∈ M, γp is a timelike curve such that q lies on it and an initial segment of γp coinc ...

Intensity and State Estimation in Quantum Cryptography
... The polarization rotation protocols are based on fundamental cryptographic primitives [10]. The protocol called iAQC [5] is a variant of three-stage in which Alice and Bob track the intensity of the laser beam at each stage making it possible to detect the intruder. But the drawback of iAQC lies in ...

Macroscopic Distinguishability Between Quantum States
... as in many other, highly physical relevant cases, the macroscopic features of matter are given through the features of its quantum states, the question of quantifying those macroscopic properties given by many-body quantum states arises as a relevant problem in physics. In this study, we are interes ...
