Generation of continuous-variable high-dimensional entanglement with three degrees of freedom and multiplexing quantum dense coding
文献摘要：
High-dimensional entanglement is a critical foundation for the growing demand for information capacity to implement the high-capacity quantum task.Here,we report continuous-variable high-dimensional entanglement with three degrees of freedom(frequency,polarization,and orbital angular momentum)directly generated with a single type-Ⅱ optical parametric oscillator(OPO)cavity.By compensating both for dispersion in frequency modes and astigmatism in higher-order transverse modes,the OPO is capable of oscillating simultaneously and outputting thousands of entanglement pairs.The three degrees of freedom high-dimensional entanglement are verified simultaneously possessing frequency comb,spin,and orbital angular momentum entanglement via 14 pairs of Hermite-Gaussian mode correlations measurement.Then,the"space-frequency"multiplexing quantum dense coding communication is also demonstrated by using the entanglement resource.It shows the great supe-riority of high-dimensional entanglement in implementing the high-capacity quantum task.Apart from an in-creased channel capacity,it is possible to conduct deterministic high-dimensional quantum protocols,quantum imaging,and especially quantum computing.
