Abstract

We achieve a narrow-band frequency-entangled photon-pair source using the cavity-enhanced spontaneous parametric down conversion. The bandwidth of photon pairs is 1.07 MHz at 605.78 nm, which could be used for Pr3+ based quantum memory.

Sub-megahertz narrow-band photon pairs at 606 nm for solid-state quantum memories

We report on the development of a source of ultra-narrow-band photon pairs using the cavity-enhanced spontaneous parametric down conversion. The photon-pair source has a bandwidth of 265 ± 15 kHz at 606 nm and a spectral brightness of 216 ± 5 pairs/(s · mW · MHz) per longitudinal mode, which could be suitable for Pr3+ ion-based solid-state quantum memories.

Ultra-narrowband photon pair source for solid state quantum memories based on widely non-degenerate cavity-enhanced downconversion

Daniel Rieländer, J. Fekete, Matteo Cristiani +1 more

We present a source of ultra-narrow band, widely non degenerate photon pairs source compatible with quantum repeaters architectures. One photon is compatible with a solid state Praseodymium (Pr3+) doped crystal spin wave quantum memory, and the other photon is at telecommunication wavelengths, such that it can be transmitted over large distances in optical fibers. Pr3+doped solids absorbing photons at 606 nm have shown very promising properties as QM for light. Despite this fact, so far no experiment demonstrated storage of quantum light in Pr3+doped crystals. The main challenge to realize such a source is that the bandwidth of the memory is limited to a few MHz by the excited state spacing of the ions. To achieve the required narrow linewidth we use widely non-degenerate cavity enhanced spontaneous down conversion (SPDC). We measure a correlation time of 104 ns, the longest reported to date for SPDC emitted photons, corresponding to around 2 MHz bandwidth. In addition, the number of longitudinal modes emitted by the source is strongly reduced, thanks to a clustering effect, which facilitates the filtering to reach single mode operation.

Ultranarrow-Band Photon-Pair Source Compatible with Solid State Quantum Memories and Telecommunication Networks

J. Fekete, Daniel Rieländer, Matteo Cristiani +1 more

We report on a source of ultranarrow-band photon pairs generated by widely nondegenerate cavity-enhanced spontaneous down-conversion. The source is designed to be compatible with Pr(3+) solid state quantum memories and telecommunication optical fibers, with signal and idler photons close to 606 nm and 1436 nm, respectively. Both photons have a spectral bandwidth around 2 MHz, matching the bandwidth of Pr(3+) doped quantum memories. This source is ideally suited for long distance quantum communication architectures involving solid state quantum memories.

Generation of Narrow-Band Polarization-Entangled Photon Pairs at a Rubidium D1 Line

Long Tian, Shujing Li, Haoxiang Yuan +1 more

Using the process of cavity-enhanced spontaneous parametric down-conversion (SPDC), we generate a narrow-band polarization-entangled photon pair resonant on the rubidium (Rb) D1 line (795 nm). The degenerate single-mode photon pair is selected by multiple temperature controlled etalons. The linewidth of generated polarization-entangled photon pairs is 15 MHz which matches the typical atomic memory bandwidth. The measured Bell parameter for the polarization-entangled photons S=2.73+-0.04 which violates the Bell-CHSH inequality by ~18 standard deviations. The presented entangled photon pair source could be utilized in quantum communication and quantum computing based on quantum memories in atomic ensemble.

Generation of Narrow-Band Polarization-Entangled Photon Pairs for Atomic Quantum Memories

Xiao‐Hui Bao, Yong Qian, Jian Hua Yang +4 more

We report an experimental realization of a narrow band polarization-entangled photon source with a linewidth of 9.6 MHz through cavity-enhanced spontaneous parametric down-conversion. This linewidth is comparable to the typical linewidth of atomic ensemble-based quantum memories. Single-mode output is realized by setting a reasonable cavity length difference between different polarizations, using of temperature controlled etalons and actively stabilizing the cavity. The entangled property is characterized with quantum state tomography, giving a fidelity of 94% between our state and a maximally entangled state. The coherence length is directly measured to be 32 m through two-photon interference.
