... With this source another loophole was closed in Zeilinger’s experiment: One remaining problem in Aspect’s experiment was that the position of the polarizers was changed periodically and thus in a predictable way. The experiment performed by the group of Zeilinger used two detectors for analysis of t ...

Implementation of a quantum algorithm on a nuclear magnetic
... where B5 $ 0,1% is the set of possible values for a single bit. Such functions take a single bit as input, and return a single bit as their result. Clearly there are exactly four such functions, which may be described by their truth tables, as shown in Table II. These four functions can be divided i ...

... This state represents a classical probability distribution over the possible meter configurations, where the probabilities are given as |α|2 to be in state |µ0 i and |β|2 to be in state |µ1 i. Unfortunately, that’s the best we can do to describe the physics of a measurement: a quantum system in a su ...

A bulk/boundary correspondence relates a (d+1)-dimensional quantum system to another quantum system that lives on the (d)-dimensional boundary of the bulk space such that the physical properties of one system can be derived from the other. In this talk I'll introduce two new approaches to the bulk/b ...
