... and we conclude that entangled biphotons are not generated even though both pump lasers are still producing photons. The observed photon interference in Fig. 2(b) has a measured visibility of V raw ¼ 93.3 2.0%. When the accidental counts are subtracted (removing the noise from the detectors and ot ...

Spatial spread of populations is usually modeled by diffusive motion, where individuals undergo a simple random walk with no memory. However, micro-organisms and animals tend to co ...

Quantum Query Lower Bounds: The Adversary Method
... So far in this course we’ve seen (0). In this lecture, we will develop a basic version of (2), the already basic adversary method. A generalized form of method (2), method (3), is extremely powerful. Indeed, it can be shown that every lower bound shown using this method has a corresponding upper bou ...
