For questions related to quantum multiplexer/demultiplexer circuits. In quantum communication, all of the system channels can be accommodated into a single channel in a larger Hilbert space. In the scheme, a single line combines the information of all the users, and, at the receiver, the original quantum channels are recovered. A multiplexer/demultiplexer circuit can perform this n qubits to qudit transformation. (arXiv:quant-ph/0701145)

What do "$i$-th basic network", "quantum multiplexers" and "quantum parallelism" mean in this context? How are they beneficial?
I have been reading the paper A quantum-implementable neural network model (Chen et al., 2017) for a few days now, but failed to understand how exactly their algorithm offers a speedup over the classical neural network models.
In particular I'm…

Problems building a multiplexer and a full quantum adder on Qiskit
I'll start with the problem I have relative to the multiplexer, I built a simple 2*1 Mux using just CX, but from what I understood Qiskit has the gate UCGate that can be used as multiplexer so I am trying to implement a multiplexer with n controls,…
