“That quantum physics, and entanglement, is here to stay,” says Eve, “and really does describe how the universe works. Even if Einstein didn't like it.” “Boom!” says Betty. So, quantum entanglement is almost certainly real. Scientists have proven beyond just about all doubt that it works. As for how it works, well, that’s another.

Quantum physics, the science of the very smallest structures in the universe, is an exotic and “spooky” world. Yet it governs so much of the technology we use in our everyday lives, from phones and computers to fluorescent light bulbs. One area where quantum technology may one day revolutionize our world is in communications.Providing “instantaneous transfer of information” and incredibly secure connections, has attracted scientific research for years. Now a new study by a team of Chinese scientists have taken us a step closer to realizing this quantum dream.Published in, the researchers explain how they managed to entangle two clouds of quantum memories over distances of 22 kilometers (13.7 miles) and 50 kilometers (31.1 miles), obliterating the previous record of 1.3 kilometers (0.8 miles). Having achieved “city-sized” distances of entanglement, the researchers believe the possibility of building a prototype quantum network is slowly becoming closer to reality.Quantum memories, which in some ways are like our current computer memory, contain quantum information (qubits), which in this case are stored on 100 million very cold Rubidium atoms in a vacuum chamber. However, unlike our current computer memory, qubits can exist in many states, known as superposition, which allows them to perform multiple calculations at the same time. If one set of quantum memory is entangled with another, the state of each memory is shared with the other.To get to this point of entanglement is incredibly complex.

The works of mercy images. If you’ve ever thought about giving a homeless person a dollar, and then judged that they might not use it in the way you’d like them to, you know what that feels like.As followers of Christ, we are supposed to be the hands and feet of Jesus in this world. It’s not pretty or easy; It is the ultimate surrender to God’s will. In His most passionate act of mercy on our behalf, Jesus’ hands and feet are broken and bleeding. They are pierced with nails and He cries out, “I thirst.” He has been rejected. But looking up at the cross, we realize just how hard that can be.

Even Einstein famously described quantum entanglement as “spooky action at a distance”. When particles are brought close enough together, they interfere with and influence one another. Once these particles are separated, a manipulation to one particle heralds an instantaneous change to the other., entangled photons managed to be sent a distance of 1,200 kilometers (745 miles) between Earth and a satellite.

However, managing to maintain entanglement of larger systems over such distances (containing more information) has proved more difficult.Here enters the latest study. Pan Jian-Wei, often the “Father of Quantum” in China, along with his colleagues, first entangled each system of atoms (called nodes) with a single photon. Altering the frequency of the photons allowed them to be sent along fiber-optic cables, where they met at a central point.
