Resolving Fock states near the Kerr-free point of a superconducting resonator

Yong Lu, Marina Kudra, Timo Hillmann +4

We have designed a tunable nonlinear resonator terminated by a SNAIL (Superconducting Nonlinear Asymmetric Inductive eLement). Such a device possesses a sweet spot in which the ext…

Propagating Wigner-Negative States Generated from the Steady-State Emission of a Superconducting Qubit

Yong Lu, Ingrid Strandberg, Fernando Quijandría +3

We experimentally demonstrate the steady-state generation of propagating Wigner-negative states from a continuously driven superconducting qubit. We reconstruct the Wigner function…

Collective radiation from distant emitters

Kanu Sinha, Alejandro González-Tudela, Yong Lu +1

Waveguides allow for direct coupling of emitters separated by large distances, offering a path to connect remote quantum systems. However, when facing the distances needed for prac…

Characterizing decoherence rates of a superconducting qubit by direct microwave scattering

Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +8

We experimentally investigate a superconducting qubit coupled to the end of an open transmission line, in a regime where the qubit decay rates to the transmission line and to its o…

Numerical study of Wigner negativity in one-dimensional steady-state resonance fluorescence

Ingrid Strandberg, Yong Lu, Fernando Quijandría +1

In a numerical study, we investigate the steady-state generation of nonclassical states of light from a coherently driven two-level atom in a one-dimensional waveguide. Specificall…
