... topological vector space E into its continuous dual space E∗ is said to be symmetric if (2) is satisfied for all elements x and y in the domain of A. This usage is fairly standard in the functional analysis literature. A symmetric everywhere defined operator is self-adjoint. By the Hellinger-Toeplit ...
Seeing a single photon without destroying it
... Light detection is usually a destructive process, in that detectors annihilate photons and convert them into electrical signals, making it impossible to see a single photon twice. But this limitation is not fundamentalÐquantum non-demolition strategies1±3 permit repeated measurements of physically o ...

... we seek an answer to the above question that relies on some analogue of the Lagrangian action. In 1920, P.A.M. Dirac made a mysterious comment to this effect, which later inspired Richard Feynman. Consider a trajectory x(t) between an initial point (x0 , t0 ) and possible future point (x′ , t′ ). Le ...

Dense Coding - School of Computing Science
... We have defined a formal language, CQP, for modelling systems which combine quantum and classical computation and communication. CQP is based on a combination of the pi calculus and Selinger’s language QPL. Details of the semantics have also been influenced by Jorrand & Lalire’s QPAlg. CQP has a sta ...
