    "abstract": "We studied optical coherence properties of the 1.53 $\\mu$m telecommunication\ntransition in an Er$^{3+}$-doped silicate optical fiber through spectral\nholeburning and photon echoes. We find decoherence times of up to 3.8 $\\mu$s at\na magnetic field of 2.2 Tesla and a temperature of 150 mK. A strong\nmagnetic-field dependent optical dephasing was observed and is believed to\narise from an interaction between the electronic Er$^{3+}$ spin and the\nmagnetic moment of tunneling modes in the glass. Furthermore, we observed\nfine-structure in the Erbium holeburning spectrum originating from\nsuperhyperfine interaction with $^{27}$Al host nuclei. Our results show that\nEr$^{3+}$-doped silicate fibers are promising material candidates for quantum\nstate storage.",
