Abstract In this paper, we propose two schemes for asymmetric bidirectional controlled remote state preparation (BCRSP) via seven-qubit and ten-qubit entangled states as the quantum channel and in real and complex Hilbert space, respectively. In these schemes, two distant parties, Alice and Bob, are not only senders but also receivers, and Alice wants to remotely prepare a single-qubit state at Bob’s site; at the same time, Bob wishes to help Alice remotely prepare a tripartite three-qubit W-type state. It is shown that only if the two senders and the controller collaborate with each other, the asymmetric BCRSP can be completed successfully.
