English:Quantum circuit diagram of a controlled-Z (CZ) / controlled-sign (CSIGN) / controlled-phase (CPHASE) / controlled-phaseflip (CFP) gate. The gate matrix is $\left({\begin{array}{cc}1&0&0&0\\0&1&0&0\\0&0&1&0\\0&0&0&-1\\\end{array}}\right)$ in the basis $\{|00\rangle ,|01\rangle ,|10\rangle ,|11\rangle \}$.
