Adaptive Phase Measurements in Linear Optical Quantum Computation [PDF]

open access: yes, 2005
Photon counting induces an effective nonlinear optical phase shift on certain states derived by linear optics from single photons. Although this no nlinearity is nondeterministic, it is sufficient in principle to allow scalable linear optics quantum ...

Measurement methods and analysis tools for rail irregularities. A case study for urban tram track [PDF]

open access: yes, 2015
Rail irregularities, in particular for urban railway infrastructures, are one of the main causes for the generation of noise and vibrations. In addition, repetitive loading may also lead to decay of the structural elements of the rolling stock.
