  The generation of entanglement across different nodes in distributed quantum
architectures plays a pivotal role for different applications. In particular,
deterministic, robust, and fast protocols that prepare genuine multipartite
entangled states are highly desirable. In this article, we propose a fractional
quantum state transfer, in which the excitation of an emitter is partially
transmitted through the quantum communication channel and then absorbed at a
spatially separated node. This protocol is based on wavepacket shaping allowing
for a fast deterministic generation of Bell states among two quantum registers
and $W$ states for a general setting of $N$ qubits, either in a sequential or
simultaneous fashion, depending on the topology of the network. By means of
detailed numerical simulations, we show that genuine multipartite entangled
states can be faithfully prepared within current experimental platforms and
discuss the role of the main decoherence sources, qubit dephasing and
relaxation, depending on the network topology.
