Quantum Computing Questions
The controlled-Pauli-X gate, also known as the CNOT gate, is a two-qubit gate in quantum computing. It performs a Pauli-X gate operation on the target qubit (the second qubit) if and only if the control qubit (the first qubit) is in the state |1⟩. If the control qubit is in the state |0⟩, then the target qubit remains unchanged. This gate is widely used in quantum algorithms and quantum error correction codes.
