  We propose a method of optimally controlling state transfer through a noisy
quantum channel (spin-chain). This process is treated as qubit state-transfer
through a fermionic bath. We show that dynamical modulation of the
boundary-qubits levels suffices to ensure fast and high-fidelity state
transfer. This is achievable by dynamically optimizing the transmission
spectrum of the channel. The resulting optimal control is robust against both
static and fluctuating noise.
