... These distributions are referred to as ‘quasi’-probability because they sum up to unity, yet do not behave entirely as one would expect from probability distributions. In particular, there are (infinitely many) quantum states ρ for which the function Wρs is not a regular probability distribution for ...

Approximate Quantum Error-Correcting Codes and Secret Sharing
... Secret Sharing and Quantum Error Correction Classically, an (n, d)-secret sharing scheme splits a secret into n pieces so that no d−1 shares reveal any information about the secret, but any d shares allow one to reconstruct it. Such a scheme is already an error-correcting code, since it allows one ...

... The way a robot would go about convincing me about its feelings it that we would spend a few days living together. I am a skeptical person, but I am open-minded and might be convinced. I do, for example, believe that dogs have feelings. I have seen the looks on their faces and their wagging tails. ...
