    We have demonstrated multiplexing and demultiplexing of seven test signals using the Hadamard basis set. The encoding utilizes the sign change of the superconducting quantum interference device gain when a Φ0/2 flux shift occurs. The periodicity of the superconducting quantum interference device response allows recursive construction of in principle arbitrarily high-order Hadamard matrices out of binary addresses, and hence makes possible to access N channels by log2 N address lines.
