BEIJING: China mobile researchers have made a significant breakthrough by creating high-dimensional multipartite entangled states on a silicon photonic quantum chip, as reported by the Global Times.
The team successfully produced three-party, four-dimensional GHZ and W entangled states with fidelities reaching 93.2% and 90.1%, respectively. The experiment utilized a compact programmable silicon photonic quantum chip measuring 16 mm by 1.5 mm, suggesting the potential for scalability to larger systems.
High-dimensional quantum entanglement offers several advantages over conventional two-dimensional entanglement, including increased information carrying capacity, enhanced noise resistance, and improved stability and accuracy in quantum information transmission. This technology has promising applications in quantum communications, computing, and precision measurement.
The researchers also introduced a universal definition of high-dimensional W entangled states and developed a scalable method for generating these states by manipulating individual photons’ multiple states and employing delayed quantum measurements. China Mobile emphasized that this research paves the way for the development of larger, more powerful quantum systems.
