Continuous Tuning of the Charge-Phase Uncertainty in a Josephson Junction
Irena Padniuk, Xianzhe Zeng, Juan Carlos Cuevas +3
Quantum mechanics constrains conjugate observables from being simultaneously measurable with arbitrary precision. In a Josephson junction, these are the transferred electric charge…
Quantum and classical Shapiro steps in small Josephson junctions
Miriam Resch, Joachim Ankerhold, Brecht I. C. Donvil +2
We propose a model describing the formation of both dual (quantum) and classical Shapiro steps in small Josephson junctions. According to this model, the dual Shapiro steps are for…
Tracking a Spin-Polarized Superconducting Bound State across a Quantum Phase Transition
Sujoy Karan, Haonan Huang, Alexander Ivanovic +5
The magnetic exchange coupling between magnetic impurities and a superconductor induce so-called Yu-Shiba-Rusinov (YSR) states which undergo a quantum phase transition (QPT) upon i…
Microwave Excitation of Atomic Scale Superconducting Bound States
Janis Siebrecht, Haonan Huang, Piotr Kot +6
Magnetic impurities on superconductors lead to bound states within the superconducting gap, so called Yu-Shiba-Rusinov (YSR) states. They are parity protected, which enhances their…
Universal scaling of tunable Yu-Shiba-Rusinov states across the quantum phase transition
Haonan Huang, Sujoy Karan, Ciprian Padurariu +5
Quantum magnetic impurities give rise to a wealth of phenomena attracting tremendous research interest in recent years. On a normal metal, magnetic impurities generate the correlat…
Emission of photon multiplets by a dc-biased superconducting circuit
G. C. Ménard, A. Peugeot, C. Padurariu +12
We observe the emission of bunches of photons by a circuit made of a microwave resonator in series with a voltage-biased tunable Josephson junction. The bunches are…
