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.

第三章 量子线路 (Quantum Circuit)# 1 逻辑门与电路# 量子计算通过量子电路来实现。量子电路的本质是幺正变换和测量的组合。

for the study of quantum computation, the Boolean circuit model is by far the easiest model to generalize (being as it the closest model of the physical reality of computers). We begin with the following well known fact, stating that any computational task (mod-

This lesson introduces the quantum circuit model of computation, which provides a standard way to describe quantum computations. It also introduces a few important mathematical concepts, including inner products between vectors, the notions of orthogonality and orthonormality , and projections and projective measurements , which generalize ...

A quantum circuit is a network of quantum gates and measurements linked by wires that represent qubits, as shown below. Quantum circuits can be read like sheet music, from left to right, starting at time 0 on the left.

A circuit will act on a predefined amount of quantum data (in Qiskit, we only directly support qubits) with unitary operations (gates), measurements and resets. In addition, a quantum circuit can contain operations on classical data, including real-time computations and control-flow constructs, which are executed by the controllers of the QPU.
