    "abstract": "Recently, atomic ensemble and single photons were successfully entangled by\nusing collective enhancement [D. N. Matsukevich, \\textit{et al.}, Phys. Rev.\nLett. \\textbf{95}, 040405(2005).], where atomic internal states and photonic\npolarization states were correlated in nonlocal manner. Here we experimentally\nclarified that in an ensemble of atoms and a photon system, there also exists\nan entanglement concerned with spatial degrees of freedom. Generation of\nhigher-dimensional entanglement between remote atomic ensemble and an\napplication to condensed matter physics are also discussed.",
