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…
How to Measure the Quantum State of Collective Atomic Spin Excitation
Koji Usami, Jun-ichi Takahashi, Mikio Kozuma
The spin state of an atomic ensemble can be viewed as two bosonic modes, i.e., a quantum signal mode and a -numbered ``local oscillator'' mode when large numbers of spin-1/2 ato…
Entanglement of orbital angular momentum states between an ensemble of cold atoms and a photon
R. Inoue, N. Kanai, T. Yonehara +3
Recently, atomic ensemble and single photons were successfully entangled by using collective enhancement [D. N. Matsukevich, \textit{et al.}, Phys. Rev. Lett. \textbf{95}, 040405(2…
