From Low-Distortion Norm Embeddings to Explicit Uncertainty Relations and Efficient Information Locking
uncertainty relations information locking low-distortion norm embedding
2010/11/5
We exploit a connection between uncertainty relations and low-distortion embeddings of L2 into L1, which allows us to adapt an explicit low-distortion embedding to obtain efficient entropic uncertaint...
We show with explicit formulas that one can completely identify an unknown quantum process with only one weakly entangled state; and identify a quantum optical Gaussian process with either one two-mo...
