Towards polarization-based, low-latency quantum communication over hollow-core conjoined-tube fibers at around 800 nm

We experimentally demonstrate high-fidelity (~0.98), polarization-based single-photon transmission and entanglement distribution over a 36-meter-long, low-loss (<10 dB/km), 800 nm- guiding hollow-core conjoined-tube fiber quantum channel, which inherently possesses low transmission latency.
