The breakthrough could revolutionise the future of quantum computing

Scientists in Germany and Austria have just made an enormous breakthrough in the field of quantum computing.
Using a record system of 20 quantum bits, physicists have achieved a new entanglement record: the largest entangled quantum register of individually controllable systems in history.
What is quantum entanglement?
In quantum physics, “entangled” particles are connected to each other meaning that any action performed on one particle affects the behaviour of the other, even if they’re separated by vast distances. If, for example, you measure the “up” spin of a photon in an entangled pair, the spin of the other will measure as “down”.
Albert Einstein called entanglement “spooky action at a distance” and he had trouble reconciling the theory as it suggests information between the two particles can travel faster than the time it takes for light to pass from one particle to another.
