Time frequemcy cluster state group

Time-frequency domain cluster states can carry large amounts of quantum information. In previous studies, scientists often used the polarization, position, and momentum of light to observe how these quantum states maintain large-scale entanglement over long distances. Therefore, cluster states are widely used in quantum repeaters and quantum computing. Compared to other quantum states, time-frequency domain cluster states have a key advantage: they greatly reduce the impact of losses during photon transmission through optical fibers. For example, polarization states can be affected by dispersion in fibers, causing the polarization to become scrambled. However, time-frequency domain cluster states significantly lower the impact of such issues.
