Weyl Josephson Circuits
Valla Fatemi, Anton R. Akhmerov, Landry Bretheau
We introduce Weyl Josephson circuits: small Josephson junction circuits that simulate Weyl band structures. We first formulate a general approach to design circuits that are analog…
Tunneling spectroscopy of graphene nanodevices coupled to large-gap superconductors
Joel I-Jan Wang, Landry Bretheau, Daniel Rodan-Legrain +4
We performed tunneling spectroscopy measurements of graphene coupled to niobium/niobium-nitride superconducting electrodes. Due to the proximity effect, the graphene density of sta…
Electrically Tunable Low Density Superconductivity in a Monolayer Topological Insulator
Valla Fatemi, Sanfeng Wu, Yuan Cao +6
The capability to switch electrically between superconducting and insulating states of matter represents a novel paradigm in the state-of-the-art engineering of correlated electron…
Quantum coherent control of a hybrid superconducting circuit made with graphene-based van der Waals heterostructures
Joel I-Jan Wang, Daniel Rodan-Legrain, Landry Bretheau +14
Quantum coherence and control is foundational to the science and engineering of quantum systems. In van der Waals (vdW) materials, the collective coherent behavior of carriers has…
Quantum dynamics of an electromagnetic mode that cannot contain N photons
Landry Bretheau, Philippe Campagne-Ibarcq, Emmanuel Flurin +2
Electromagnetic modes are instrumental in building quantum machines. In this experiment, we introduce a method to manipulate these modes by effectively controlling their phase spac…
Parameter estimation from measurements along quantum trajectories
Pierre Six, Philippe Campagne-Ibarcq, Landry Bretheau +2
The dynamics of many open quantum systems are described by stochastic master equations. In the discrete-time case, we recall the structure of the derived quantum filter governing t…
