WebAug 2, 2011 · Our method will allow simplification of small-scale linear optical circuits. For example, the CNOT gate (or other entangling gates) demonstrated above could be combined with a postselected version ... WebJun 18, 2024 · The most important feature of a CNOT gate is its quantum operation: with the control in a superposition and the target in a logical basis state, the output of the CNOT gate is an entangled state—the quintessential quantum mechanical state. Figure 2: Experimental demonstration of classical CNOT operation—operation in the logical basis.
WebDec 16, 2001 · A deterministic CNOT gate would require either very high non-linearities … The CNOT gate operates on a quantum register consisting of 2 qubits. The CNOT gate flips the second qubit (the target qubit) if and only if the first qubit (the control qubit) is . If are the only allowed input values for both qubits, then the TARGET output of the CNOT gate corresponds to the result of a classical XOR gate. Fixing CONTROL as , the TARGET output of the CNOT gate yields the result of a classical NOT gate.
