Active laser frequency stabilization using neutral praseodymium (Pr)
S. Oppel, G. H. Guthoehrlein, W. Kaenders +1
We present a new possibility for the active frequency stabilization of a laser using transitions in neutral praseodymium. Because of its five outer electrons, this element shows a…
A versatile source of polarization-entangled photons
A. Maser, R. Wiegner, U. Schilling +2
We propose a method for the generation of a large variety of entangled states, encoded in the polarization degrees of freedom of N photons, within the same experimental setup. Star…
Measuring arbitrary-order coherences: Tomography of single-mode multiphoton polarization-entangled states
Uwe Schilling, Joachim von Zanthier, Girish S. Agarwal
A scheme is discussed for measuring Nth-order coherences of two orthogonally polarized light fields in a single spatial mode at very limited experimental cost. To implement the sch…
Heralded Entanglement of Arbitrary Degree in Remote Qubits
U. Schilling, C. Thiel, E. Solano +2
Incoherent scattering of photons off two remote atoms with a Lambda-level structure is used as a basic Young-type interferometer to herald long-lived entanglement of an arbitrary d…
