Dispersive detection of a charge qubit with a broadband high-impedance quantum-Hall plasmon resonator
Chaojing Lin, Kosei Teshima, Takafumi Akiho +2
Cavity quantum electrodynamics (cQED) provides strong light-matter interactions that can be used for manipulating and detecting quantum states. The interaction can be enhanced by i…
Efficient heat-energy conversion from a non-thermal Tomonaga-Luttinger liquid
Hikaru Yamazaki, Masashi Uemura, Haruhi Tanaka +5
Energy harvesting is a technique that generates useful work from waste heat. Conventional energy harvesters acting on local thermal equilibrium states are constrained by thermodyna…
Coulomb oscillations of a quantum antidot formed by an airbridged pillar gate in the integer and fractional quantum Hall regime
Tokuro Hata, Hiroki Mitani, Hidetaka Uchiyama +3
Quantum antidots (QAD) are attractive for manipulating quasiparticles in quantum Hall (QH) systems. Here, we form a QAD in the integer and fractional QH regimes at nominal Landau-l…
Static quantum dot on a potential hilltop for generating and analyzing hot electrons in the quantum Hall regime
Ryo Oishi, Yuto Hongu, Tokuro Hata +4
We propose and demonstrate a static quantum dot on a potential hilltop to generate and analyze ballistic hot electrons along a quantum Hall edge channel well above the chemical pot…
Resonant plasmon-assisted tunneling in a double quantum dot coupled to a quantum-Hall plasmon resonator
Chaojing Lin, Ko Futamata, Takafumi Akiho +2
Edge magnetoplasmon is an emergent chiral bosonic mode promising for studying electronic quantum optics. While the plasmon transport has been investigated with various techniques f…
