A quantum circuit is a model for quantum computation that describes a computation as a sequence of quantum gates, measurements, and qubit initializations, arranged much like a classical logic circuit. In the standard diagram, horizontal lines represent the passage of time from left to right, with a single line representing one qubit and a doubled line representing a classical bit, while gates and measurements are drawn along the lines in the order they occur. The physicist Richard Feynman used an early version of this notation in 1986, and the diagrams borrow a variant of the graphical notation Roger Penrose developed for tensor networks. To actually perform quantum computation, a circuit's physical implementation must satisfy what is known as DiVincenzo's criteria, the minimum set of capabilities a system needs to manipulate qubits reliably.

In quantum information theory, a quantum circuit is a model for quantum computation, similar to classical circuits, in which a computation is a sequence of quantum gates, measurements, initializations of qubits to known values, and possibly other actions.
