In quantum computation, a quantum circuit diagram is a kind of string diagram in finite-dimensional Hilbert spaces, typically used to express a sequence of low-level quantum gates acting on a finite number of qbits.

At the time of writing (2021) most of the actual programming of experimental quantum computers is conceived through quantum circuit diagrams, while more high-level quantum programming languages are are awaiting the rise of more powerful quantum hardware.
