Contacting Josephson Junctions via Airbridges in Superconducting Circuits

Prakiran Baidya, Momčilo Milosavljević, Murali Krishna Kurmapu +6

Superconducting circuit devices require electrical interconnects between different circuit elements on the chip, for which conventional device architectures use a combination of tw…

Experimental Demonstration of Commutation Relations Using Intensity Correlations

Hans Dang, Sebastian Luff, Martin Fischer +4

The canonical commutation relation is a cornerstone of quantum theory and underlies the Heisenberg uncertainty principle. Although uncertainty relations have been extensively teste…

Feedback Cooling and Thermometry of a Single Trapped Ion Using a Knife Edge

Hans Dang, Sebastian Luff, Martin Fischer +2

We report on a simple and easy to implement method of feedback cooling trapped ions to temperatures below those achievable using only Doppler cooling. Additionally, the feedback co…

Measuring the temperature and heating rate of a single ion by imaging

Bharath Srivathsan, Martin Fischer, Lucas Alber +3

We present a technique based on high resolution imaging to measure the absolute temperature and the heating rate of a single ion trapped at the focus of a deep parabolic mirror. We…

Single photons emitted by nano-crystals optically trapped in a deep parabolic mirror

Vsevolod Salakhutdinov, Markus Sondermann, Luigi Carbone +3

We investigate the emission of single photons from CdSe/CdS dot-in-rods which are optically trapped in the focus of a deep parabolic mirror. Thanks to this mirror, we are able to i…

Shifting the phase of a coherent beam with a Yb ion: influence of the scattering cross section

Martin Fischer, Bharath Srivathsan, Lucas Alber +3

We discuss and measure the phase shift imposed onto a radially polarized light beam when focusing it onto an ion. In the derivation of the expected phase shif…
