Detect Broader Multi-particle Entanglement Green Laser Pointer
In the latest research. The team uses green laser pointer. Twenty calcium atoms were entangled with each other in the ion trap experiment, and the dynamic expansion of multi-particle entanglement in the system was observed. Lanyon said: Particles are entangled in pairs first, through the latest method we developed. We can prove it. The entanglement further spread to all particle triplets adjacent to the green laser pointer. Most quadruplets and several pentads.

Application
Nicolas Forres, the first author of the latest study, emphasized. We have detected entanglement between a large number of particles in many quantum systems, including ultra-cold gases. But the latest experiments can address and read each qubit. Therefore, it is suitable for specific applications such as quantum simulation or quantum information processing. The research team hopes to further increase the number of qubits in the experiment. "Our medium-term goal is 50 particles. This can help us solve the problem that the best supercomputers currently cannot be cracked." They also plan to optimize methods. To detect the broader multi-particle entanglement of the green laser pointer.
