Quantum coding with finite resources
... can be used many times in sequence. In this case, the sender first encodes a quantum state into a sequence of registers and then sends them one by one through the channel to the receiver. The receiver collects these registers and then attempts to decode the quantum state. Equivalently, one considers ...

Studies of effective theories beyond the Standard Model
... The vast majority of all experimental results in particle physics can be described by the Standard Model (SM) of particle physics. However, neither the existence of neutrino masses nor the mixing in the leptonic sector, which have been observed, can be described within this model. In fact, the model ...

The remarkable correspondence between high frequency modes for an integrable system and its invariant tori, is the reason that Bohr was able to develop quantum theory for the hydrogen atom using only classical orbits. ...
