EU-funded scientists have made an important step towards exploiting the weird behaviour of quantum many-body systems in a controlled way. They developed a test to certify the proper functioning of photonic quantum simulators.
Over the past two decades, scientists made impressive progress towards the development of a general purpose quantum computer. However, such a device with the power to solve problems in a fraction of the time it takes the world's fastest supercomputers is still far from realisable.
