- Abstract: Quantum teleportation is essential for many quantum information technologies
including long-distance quantum networks. Using fiber-coupled devices,
including state-of-the-art low-noise superconducting nanowire single photon
detectors and off-the-shelf optics, we achieve quantum teleportation of
time-bin qubits at the telecommunication wavelength of 1536.5 nm. We measure
teleportation fidelities of >=90% that are consistent with an analytical model
of our system, which includes realistic imperfections. To demonstrate the
compatibility of our setup with deployed quantum networks, we teleport qubits
over 22 km of single-mode fiber while transmitting qubits over an additional 22
km of fiber. Our systems, which are compatible with emerging solid-state
quantum devices, provide a realistic foundation for a high-fidelity quantum
internet with practical devices.
