Abstract

We present two new schemes for quantum memories in warm alkali vapor In one scheme we map the optical field onto the superposition between electronic orbitals in a ladder level scheme Our fast ladder memory FLAME demonstrates high bandwidth long lifetime and low noise and is thus highly suitable for quantum network synchronization Potentially FLAME can be performed in miniature vapor cell devices including optical confinement and be readily integrated with Rydberg level excitations In the second scheme we achieve a record 150 millisecond memory lifetime at room temperature by mapping the optical field onto ground state spin orientation which is insensitive to spin exchange collisions This scheme paves the way towards hour long memories using rare gas nuclear spins
