Cryogenic amplification of image-charge detection for readout of quantum states of electrons on liquid helium
Asem Elarabi, Erika Kawakami, Denis Konstantinov
Accurate detection of quantum states is a vital step in the development of quantum computing. Image-charge detection of quantum states of electrons on liquid helium can potentially…
Relaxation of the Excited Rydberg States of Surface Electrons on Liquid Helium
Erika Kawakami, Asem Elarabi, Denis Konstantinov
We report the first direct observation of the decay of the excited-state population in electrons trapped on the surface of liquid helium. The relaxation dynamics, which are governe…
Mutually synchronized macroscopic Josephson oscillations demonstrated by polarization analysis of superconducting terahertz emitters
M. Tsujimoto, S. Fujita, G. Kuwano +7
We demonstrate mutual synchronization of Josephson oscillations in multiple stacks of intrinsic Josephson junctions of the cuprate superconductor BiSrCaCuO. Det…
Image-charge detection of the Rydberg states of surface electrons on liquid helium
Erika Kawakami, Asem Elarabi, Denis Konstantinov
We propose and experimentally demonstrate a new spectroscopic method, image-charge detection, for the Rydberg states of surface electrons on liquid helium. The excitation of the Ry…
Monolithic superconducting emitter of tunable circularly polarized terahertz radiation
A. Elarabi, Y. Yoshioka, M. Tsujimoto +1
We propose an approach to control the polarization of terahertz (THz) radiation from intrinsic Josephson-junction stacks in single crystalline high-temperature superconductor $Bi_2…
