Choosing the rules of quantum physics as the physical basis for constructing models of computation allows for solving certain computational problems more efficiently as in models based on classical physics. In the quantum circuit model, information is encoded in quantum bits and manipulated by applying appropriate quantum operations acting on the joint state space of the qubits. Similar to what is done in classical computation, these quantum operations can be decomposed into a sequence of gate operations, consisting of single-qubit operations and entangling operations acting on pairs of qubits.
