We present an experimental demonstration of novel Quantum-dot Cellular Automata (QCA) devices based on clocked architecture -- a QCA latch and a two-bit QCA shift register. The operation of the devices is demonstrated, and sources of the digital errors occurring in clocked QCA devices are discussed.
