Oblak, F. Bussières, M. George, R. Ricken, W. Sohler, W. Tittel | | Broadband waveguide quantum memory for entangled photonsReversible mapping of quantum states, particularly entangled states, between light and matter is important for advanced applications of quantum information science. This mapping, i.e. operation of a quantum memory [1], is imperative for realizing quantum repeaters [2] and quantum networks [3]. Here we report the reversible transfer of photon–photon entanglement into entanglement between a photon and a collective atomic excitation in a solid-state device [4] (see also [5]). Specifically, we generate time-bin enangled pairs of photons [6] at the low-loss 795 nm (in free-space) and 1532 nm (in fibre) wavelengths. The 795 nm photons are sent into a thulium-doped lithium niobate waveguide cooled to 3K, absorbed by the Tm ions, and retrieved after 7 ns by means of a photon-echo quantum memory protocol employing an atomic frequency comb [7]. The acceptance bandwidth of the memory has been expanded to 5 GHz, more than one order of magnitude larger than the previous state-of-the-art [8], to match the spectral width of the filtered 795 nm photons. The entanglement-preserving nature of our storage device is assessed through quantum state tomography before and after storage. Within statistical error, we find a perfect mapping process. Furthermore, by violating the CHSH inequality [9], we directly verify the nonlocal nature of the generated and stored entangled photons.

Actualizing a quantum interface [2] between light and matter is imperative for construction of a quantum repeater [3], which requires a faithful mapping of quantum entanglement [1] between light and matter. In this work we report the reversible transfer of photon-photon entanglement into entanglement between a photon and a collective atomic excitation in a solid-state thulium-doped lithium niobate waveguide [4] (this transfer was simultaneously done in [5]).

Sohler | | Frequency-multiplexed photon storage and read-out on demand using an atomic frequency comb-based quantum memoryOptical quantum memories require the ability to reversibly map quantum states between photons and atoms [1]. When employed for quantum repeaters [2], quantum memories are key to enabling long-distance quantum communication. Towards this end, quantum memories require recall on demand with high fidelity and efficiency, long storage times, and the possibility to simultaneously store multiple carriers of quantum information. The combination of a quantum state storage protocol based on an atomic frequency comb (AFC) [3] with rare-earth-ion doped crystals cooled to cryogenic temperatures as storage materials [4] has been shown to meet many of these requirements. In particular, it is well suited for storage of temporally multiplexed photons [5,6]. Yet, despite first proof-of-principle demonstrations [7], recalling quantum information at a desired time (i.e. read-out on demand) with broadband, single-photon-level pulses remains an outstanding challenge.
We will present the first experimental demonstration of frequency-multiplexed storage of attenuated laser pulses followed by read-out on demand in the frequency domain. Our work is based on the AFC protocol and employs a Tm-doped LiNbO3 waveguide [8,9]. We will argue that, in view of a quantum repeater, our approach is equivalent to temporal multiplexing and read-out on demand in the temporal domain. This overcomes one further obstacle to building quantum repeaters using rare-earth-ion doped crystals as memory devices.

Tittel | | Quantum memory and entanglementReversibly mapping entanglement between photons and atoms, which serve as quantum memory, and projecting independent (pure) photonic quantum states after recall from such a memory onto entangled states are key to quantum repeaters and, more generally, quantum networks [1]. In this talk we present the reversible mapping of quantum information encoded into one of two time-bin entangled photons using a photon-echo quantum memory protocol [2] (for closely related work see [3]). Our results show, within experimental uncertainty, that the encoded quantum information, i.e. the property of the stored photon being one member of an entangled pair, can be retrieved without degradation. Furthermore, we will demonstrate two-photon interference and the projection onto an entangled state using attenuated pulses of light (featuring an average of less than one photon per pulse) that have, or have not, been reversibly mapped to separate quantum memories. As the interference visibility is close to the theoretical maximum, regardless of whether none, one, or both pulses have previously been stored, we conclude that our solid-state quantum memories preserve not only encoded quantum information, but the entire photonic wave function during storage. Both investigations take advantage of thulium-doped lithium niobate waveguide quantum memories as storage materials, and employ a photon-echo type quantum memory approach based on atomic frequency combs [4]. Our findings complete previously missing steps towards advanced applications of quantum information processing, and bring us closer to building quantum repeaters, networks, and linear optics quantum computers.
