  Quantum teleportation is an essential capability for quantum networks,
allowing the transmission of quantum bits (qubits) without a direct exchange of
quantum information. Its implementation between distant parties requires
teleportation of the quantum information to matter qubits that store it for
long enough to allow users to perform further processing. Here we demonstrate
long distance quantum teleportation from a photonic qubit at telecom wavelength
to a matter qubit, stored as a collective excitation in a solid-state quantum
memory. Our system encompasses an active feed-forward scheme, implementing a
phase shift on the qubit retrieved from the memory, therefore completing the
protocol. Moreover, our approach is time-multiplexed, allowing for an increase
in the teleportation rate, and is directly compatible with the deployed
telecommunication networks, two key features for its scalability and practical
implementation, that will play a pivotal role in the development of
long-distance quantum communication.
