Quantum Computing Questions
The controlled-T gate, also known as the controlled-Toffoli gate or the controlled-controlled-Z gate, is a quantum gate that operates on two qubits. It is an extension of the controlled-Z gate, where a T gate is applied to the target qubit if and only if the control qubit is in the state |1⟩. The controlled-T gate is commonly used in quantum algorithms and quantum error correction codes.
