Generating two continuous entangled microwave beams using a dc-biased Josephson junction
A. Peugeot, G. Ménard, S. Dambach +14
We show experimentally that a dc-biased Josephson junction in series with two microwave resonators emits entangled beams of microwaves leaking out of the resonators. In the absence…
Dynamical Coulomb Blockade as a Local Probe for Quantum Transport
Jacob Senkpiel, Jan C. Klöckner, Markus Etzkorn +9
Quantum fluctuations are imprinted with valuable information about transport processes. Experimental access to this information is possible, but challenging. We introduce the dynam…
Josephson junction cavity systems as cousins of the quantum optical micromaser
Simon Dambach, Andrew D. Armour, Björn Kubala +1
We explore the similarities and differences between simple theoretical models developed to describe the quantum optical micromaser and Josephson-photonics devices. Whilst the micro…
Single Channel Josephson Effect in a High Transmission Atomic Contact
Jacob Senkpiel, Simon Dambach, Markus Etzkorn +9
The Josephson effect in scanning tunneling microscopy (STM) is an excellent tool to probe the properties of the superconducting order parameter on a local scale through the Ambegao…
Antibunched photons emitted by a dc biased Josephson junction
C. Rolland, A. Peugeot, S. Dambach +11
We show experimentally that a dc biased Josephson junction in series with a high-enough impedance microwave resonator emits antibunched photons. Our resonator is made of a simple m…
Quantum thermodynamics with a Josephson-photonics setup
Simon Dambach, Paul Egetmeyer, Joachim Ankerhold +1
Josephson-photonics devices have emerged in the last years as versatile platforms to study light-charge interactions far from equilibrium and to create nonclassical radiation. Thei…
