Current-based RF charge sensing in a carbon nanotube
Marta Cagetti, Stefan Forstner, Victor Champain +8
The paper presents a current-mode charge sensor built from a suspended carbon nanotube that operates at a 1.25 MHz RLC resonance, achieving 0.15 µe/√Hz charge sensitivity and enabl…
Energy efficiency of quantum computers
Miquel Carrasco-Codina, Pau Escofet, Paul Hilaire +13
How much energy does a quantum computer consume? Are they more efficient than their classical counterparts? In this work, we make a step towards answering these questions. We defin…
Kondo cloud conductance in cavity-coupled quantum dots with asymmetric barriers
D. Fossion, V. Champain, S. Mohapatra +9
The Kondo effect emerges when a localized spin is screened by conduction electrons, giving rise to a strongly-correlated many-body ground state. In this work, we investigate this p…
A hole spin resilient to dipole-induced thermal effects
V. Champain, G. Boschetto, H. Niebojewski +12
Recent advances in scaling up spin-based quantum processors have revealed unanticipated issues related to thermal effects. Microwave pulses required to manipulate and read the qubi…
Unifying Floquet theory of longitudinal and dispersive readout
Alessandro Chessari, Esteban A. RodrÃguez-Mena, José Carlos Abadillo-Uriel +5
We devise a Floquet theory of longitudinal and dispersive readout in circuit QED. By studying qubits coupled to cavity photons and driven at the resonance frequency of the cavity $…
Optimal operation of hole spin qubits
Marion Bassi, Esteban-Alonso Rodrıguez-Mena, Boris Brun +11
Hole spins in silicon or germanium quantum dots have emerged as a compelling solid-state platform for scalable quantum processors. Besides relying on well-established manufacturing…
