Imagine that we are in a science fiction universe, where information, like an invisible spirit, can be transmitted instantly from one end of the earth to the other, regardless of the mountains, lakes and oceans that separate us. Such a scene once existed only in the fantasies of science fiction novels and films, but now, with a breakthrough at the University of Science and Technology of China, this seemingly unattainable dream seems to be unfolding right in front of our eyes. What kind of breakthrough is it? It's like a mysterious beam of light that travelled through the tunnel of time and space, allowing us to achieve remote quantum entanglement for the first time. It's like opening a door to another dimension where the transmission of information is no longer bound by the physical world.
If you're in New York and want to send a message to a friend in Los Angeles, you no longer have to wait for an internet signal to be transmitted or worry about interruptions or delays. Just one click and the message will appear in front of your friend's eyes instantly like lightning. And all thanks to the amazing physical phenomenon of quantum entanglement. In the quantum world, a special connection can exist between two particles that can instantly sense changes in each other's state no matter how far apart they are. This connection, like an invisible bond, connects the two particles closely together.
The quantum world is like a deep and mysterious forest, in which each particle is a bright star in the forest, and the connection between them - quantum entanglement - is like an invisible link, connecting these stars and transmitting mysterious and powerful energy. The research conducted by the University of Science and Technology of China (USTC) is like a brave explorer holding a magical key, who finally found the secret to unlock the door of the bond in this forest. With sophisticated experiments and calculations, they cleverly manipulated and transmitted these remote quantum entanglements, as if waving a magic wand in the forest, making those invisible bonds dance in space. This achievement not only gives us a glimpse of the endless treasures and huge potential in the mysterious forest of quantum communication but also paves a solid path to the world's first quantum network, which is like opening up a new path to the unknown world in the forest, leading us to a more exciting future.
The secret weapon behind this exciting breakthrough, which is like a cosmic magic show, is the mysterious and unpredictable quantum entanglement. Imagine, in the microscopic quantum world, two particles seem to be tightly connected by an invisible magic thread, they are like a pair of twins, although they may be in different corners of the world, the mind is connected, and the state is closely linked. This entanglement is so incredible that even the great scientist Albert Einstein called it ‘ghostly superlatives’. Just like you and your twin brother, even though you are on opposite sides of the globe, your telepathic connection seems to be able to sense each other's moods across thousands of miles.
In the quantum world, this sensing is even more marvellous and precise. When you observe or manipulate a particle, its state will change immediately, and at the same time, another particle thousands of miles away will change accordingly in synchronisation. The change is instantaneous and not limited by time or space, as if they are connected in a way that transcends the laws of physics.
This research by the University of Science and Technology of China is like unravelling the mystery of this cosmic magic. Through sophisticated experiments and calculations, scientists have successfully realised the manipulation and transmission of remote quantum entanglement. It is like they have found a key that can unlock the mysteries of the quantum world, allowing us to explore this microscopic world full of wonders more deeply.
