Projective measurement of a single nuclear spin qubit by using two-mode cavity QED
Yujiro Eto, Atsushi Noguchi, Peng Zhang +2
We report the implementation of projective measurement on a single 1/2 nuclear spin of the 171Yb atom by measuring the polarization of cavity-enhanced fluorescence. To obtain cavit…
Measuring Qutrit-Qutrit Entanglement of Orbital Angular Momentum States of an Atomic Ensemble and a Photon
R. Inoue, T. Yonehara, Y. Miyamoto +2
Three-dimensional entanglement of orbital angular momentum states of an atomic qutrit and a single photon qutrit has been observed. Their full state was reconstructed using quantum…
Observation of Electromagnetically Induced Transparency for a Squeezed Vacuum with the Time Domain Method
M. Arikawa, K. Honda, D. Akamatsu +5
A probe light in a squeezed vacuum state was injected into cold 87 $Rb atoms with an intense control light in a coherent state. A sub-MHz window was created due to electromagnetica…
Observation of Topological and Parity-dependent Phase of Spin States
Koji Usami, Mikio Kozuma
A Ramsey interrogation scheme was used to measure the phase shift of laser-cooled Rb clock-transition pseudospins arising as a result of a reversal of a bias magnetic field,…
Frequency filtered storage of parametric fluorescence with electromagnetically induced transparency
K. Akiba, K. Kashiwagi, T. Yonehara +1
The broadband parametric fluorescence pulse (probe light) with center frequency resonant on 87Rb D1 line was injected into a cold atomic ensemble with coherent light (control light…
Ultraslow Propagation of Squeezed Vacuum Pulses with Electromagnetically Induced Transparency
Daisuke Akamatsu, Yoshihiko Yokoi, Manabu Arikawa +4
We have succeeded in observing ultraslow propagation of squeezed vacuum pulses with electromagnetically induced transparency. Squeezed vacuum pulses (probe lights) were incident on…
