The gates available in Qiskit are only small part of quantum gates one can apply in quantum circuits. In this exercise, create the following gate and apply on a one qubit system using the operator method in qiskit. Also provide the screenshot of the Python code

$A=\frac{1}{\sqrt[\phantom{2}]{2}}({}_x+{}_y)=([0,\frac{(1-i)}{\sqrt[\phantom{2}]{2}}],[\frac{(1+i)}{\sqrt[\phantom{2}]{2}},0])$
