As the size of modern technology shrinks down to the nanoscale, weird quantum effects--such as quantum tunneling, superposition, and entanglement--become prominent. This opens the door to a new era of quantum technologies, where quantum effects can be exploited. Many everyday technologies make use of feedback control routinely; an important example is the pacemaker, which must monitor the user's heartbeat and apply electrical signals to control it, only when needed.
