It sounds strange, but our world consists of two worlds: A large, familiar world in which everything happens as we know it from experience. And below that, a microscopic world of the smallest structures, the quanta. A world that obeys its own laws. These can be used in our large world. Has the quantum age dawned? In the microscopically small world, atoms, electrons and other quantum particles behave strangely. "If I could shrink to the size of an atom, all the laws and behavior around me would contradict my understanding," says physicist Julien Bobroff. Quantum particles can assume several states at the same time - this is called superposition. And that's not all: if you entangle two quantum particles, they remain magically connected to each other even over great distances. Even the physicists Niels Bohr and Albert Einstein racked their brains over quantum phenomena. As strange as this quantum behavior is, it can be very useful to us. For example, to build high-precision measuring sensors. "The special properties of quantum particles are very fragile, however," explains quantum physicist Monika Aidelsburger. Quantum particles are so sensitive that the slightest interaction with the environment causes the superposition to disappear, which is why scientists have to proceed very carefully. Quantum has already changed our lives significantly. The invention of the laser and microchips would have been unthinkable without quantum physics. Now another invention could revolutionize our world: the quantum computer. "It would help us to develop better medicines and materials in a short time," says Ignacio Cirac from the Max Planck Institute of Quantum Optics. Many applications are not yet foreseeable today. Quantum particles and their strange behavior are about to turn our world upside down.
