Nonlocal biphoton generation in Werner state from a single semiconductor quantum dot
H. Kumano, H. Nakajima, T. Kuroda +3
We demonstrate Werner-like polarization-entangled state generation disapproving local hidden variable theory from a single semiconductor quantum dot. By exploiting tomographic anal…
Vanishing fine structure splittings in telecom wavelength quantum dots grown on (111)A surfaces by droplet epitaxy
X. Liu, N. Ha, H. Nakajima +7
The emission cascade of a single quantum dot is a promising source of entangled photons. A prerequisite for this source is the use of a symmetric dot analogous to an atom in a vacu…
Telecommunication band InAs quantum dots and dashes embedded in different barrier materials
Nahid A Jahan, Claus Hermannstädter, Jae-Hoon Huh +8
We investigate the long wavelength (1.2 to 1.55 micro-m) photoluminescence of high-density InAs quantum dots and dashes, which were grown on InP substrates. We analyze the temperat…
A Cooper pair light emitting diode
H. Sasakura, S. Kuramitsu, Y. Hayashi +7
We demonstrate Cooper-pair's drastic enhancement effect on band-to-band radiative recombination in a semiconductor. Electron Cooper pairs injected from a superconducting electrode…
