However, research in this field requires not only scientific expertise but sometimes also highly specialized laboratory conditions. Bose\u2013Einstein condensates are a remarkable example, in which atoms move in lockstep, making quantum-mechanical effects visible not only at the level of individual atoms but also on a macroscopic scale. The first Bose\u2013Einstein condensates were observed in ultracold atomic gases at temperatures close to absolute zero. The cooling required to achieve this was technically demanding, costly and restricted to specialized laboratories.<\/p>\n<p>Today, quantum research is increasingly focusing on Bose\u2013Einstein condensates in solid-state materials, which can also exist at moderate temperatures. Typically, electron-hole pairs in a semiconductor, known as excitons, are used for this purpose and can be selectively generated using laser pulses.<\/p>\n<p>Excitons, however, are too sluggish, so to speak, to move in lockstep and are therefore coupled to the light field of an optical resonator to reduce their effective mass. The result is a hybrid state of matter and light known as exciton\u2013polaritons. They offer the best of both worlds: They can be controlled using laser pulses and, because they are significantly lighter, can more easily be brought into a collective quantum-mechanical state.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Quantum technologies are considered key technologies of the future.
