Physics IV - Script of the Lecture Prof. Simon Lilly Notes from:
... The electrons hit the detector with a statistical distribution, so we observe a diffraction pattern in the locations of the detected electrons. This implies wave properties through the slits. We could ask, whether we can tell which slit the electron passed through and indeed we can quite easily, but ...

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 structure of perturbative quantum gauge theories
... Regularization: introduce a parameter z ∈ C and define new Feynman rules Uz : Γ 7→ Uz (Γ) ∈ C The previous infinity becomes a pole at z = 0 of the Laurent series expansion in z. Subtraction: get rid of the whole pole part of the Laurent series expansion: this gives the renormalized amplitude Γ 7→ Rz ...

[37], has these properties. Moreover the introduced approximations correspond to omitting terms with a well defined ...
