Quantum Computing Questions
The Pauli-Y gate is one of the fundamental quantum gates used in quantum computing. It is a single-qubit gate that represents a rotation of the qubit state around the y-axis of the Bloch sphere by 180 degrees. Mathematically, the Pauli-Y gate is represented by the following matrix:
[[0, -i],
[i, 0]]
In terms of its effect on the qubit state, the Pauli-Y gate changes the sign of the imaginary component of the qubit's probability amplitudes, while leaving the real component unchanged.
