A Simple Implementation of an Entangler Circuit by Using Quantum Linear Optics

The topic of quantum computing is one that is expanding quickly and has the potential to completely change how some difficult problems can be resolved. In recent years, there has been considerable advancement in the research and application of quantum computing technologies. The use of this technology to address challenging or impractical tasks for conventional computers is an area of ongoing research. By creating an optical entangler, a quantum-helpful circuit for generating pairs of intensely entangled states, which are useful in numerous applications including quantum teleportation, quantum dense coding, and quantum error correction, this work has demonstrated a potential application of these technologies. Although the Optical Dual Rail Mode has shown to be extremely helpful for scaling up optical quantum circuits, there are still many obstacles and issues that need to be resolved before it can be widely applied in quantum computing.
