Optical cnot gate
WebThe action of the CNOT gate can be represented by the matrix (permutation matrix form): = []. The first experimental realization of a CNOT gate was accomplished in 1995. Here, a single Beryllium ion in a trap was used. The two qubits were encoded into an optical state and into the vibrational state of the ion within the trap. WebNov 22, 2013 · 2. Optical setup for a probabilistic CNOT gate. We intend to perform a CNOT gate between the qubits and , where and are the control and the target qubits, respectively. In a coherent state quantum computer (CSQC), the qubit is encoded as and where α is assumed to be real. In this case, we have , which ensures the orthogonality if [3], [4], [5 ...

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 key two qubit gate is the Controlled Not (CNOT) gate. A deterministic CNOT gate would require either very high non-linearities mil88 or very complex linear networks KLM . Building on the latter ideas a linear, coincidence basis CNOT has been described ral which could be a useful test-bed.
