## Summary

Description
English: Quantum circuit diagram of a sqare-root-of-SWAP (${\displaystyle {\sqrt {\mathrm {SWAP} }}}$) gate. The gate matrix is ${\displaystyle \left({\begin{array}{cc}1&0&0&0\\0&{\frac {1+i}{2}}&{\frac {1-i}{2}}&0\\0&{\frac {1-i}{2}}&{\frac {1+i}{2}}&0\\0&0&0&1\\\end{array}}\right)}$ in the basis ${\displaystyle \{|00\rangle ,|01\rangle ,|10\rangle ,|11\rangle \}}$.
