A probabilistic CNOT gate for coherent state qubits

WebA major di culty for optical quantum computing is in realizing the entangling logic gates required for univer-sal quantum computation. The canonical example is the controlled-NOT gate (CNOT), which ips the state of a target (T) qubit conditional on a control (C) qubit being in the logical state \1". Figure 2A shows why this opera-tion is di cult. WebApr 11, 2024 · 1.Introduction. Intense scattering occurs as the light propagates through biological tissues, smoke, ground glass, or other scattering media. In such cases, it is tough for the conventional optical camera to capture the image of the object due to the distortion of the light field [1].However, the information about the object is still in the distorted light … grapes of wrath movie clips
