... A statistical distinguishability based on relative entropy characterizes the fitness of quantum states for phase estimation. This criterion is used to interpolate between two regimes, of local and global phase distinguishability. The analysis demonstrates that, in a passive MZI, the Heisenberg limit ...

Matrix elements for the Coulomb interaction
... Many quantum mechanical applications [4, 6-15] require the calculation of (1). In several publications, computation of these matrix elements for some specific values of k can be found, but, in general, they are restricted to the case n1 = n2 and the computation methods therein are complicated. The a ...

... A.-Ambainis 2011: Massive generalization of collision lower bound. If f is any problem whatsoever that’s symmetric under permuting the inputs and outputs, and has sufficiently many outputs (like the collision problem), then f’s classical query complexity (f’s quantum query complexity)7 Compare to ...

... This is entanglement: the strange correlation of two spatially separated quantum states. Entangled states are hard to maintain, because interactions with the environment destroy the entanglement. As a result, they are rare in our macroscopic world. But that doesn’t stop them being essential to quant ...
