Quantum group seminar:Beyond the diffraction limit in optical microscopy and lit
内容： In optical microscopy and lithography, the resolution is restricted to about half the wavelength of the light by something called the diffraction limit. Many attempts have been made to advance ...

Surprises in the theory of quantum communication
内容： I’ll discuss the central question in the theory of quantum communication: What are the capabilities of a noisy quantum communication link? Addressing this question leads us to concepts like en...

Quantum physics in the macroscopic domain
内容： I will present a wide range of research aimed at understanding quantum physics of large objects and their dynamical and thermodynamical behavior in the far-from-equilibrium domain. The first fu...

Quantum Journal Club: Pattern Formation with Trapped Ions
内容： Ion traps are a versatile tool to study nonequilibrium statistical physics, due to the tunability of dissipation and nonlinearity.We propose an experiment with a chain of ions, where dissipatio...

Quantum Journal Club: Far-field optical imaging and manipulation of individual s
内容： A fundamental limit to existing optical techniques for measurement and manipulation of spin degrees of freedom is set by diffraction, which does not allow spins separated by less than about a q...

Quantum Journal Club: Experimental Violation of Multipartite Bell Inequalities w
内容： We report on the experimental violation of multipartite Bell inequalities by entangled states of trapped ions. First, we consider resource states for measurement-based quantum computation of be...
