Candidate for unobtanium when obtaining Rydberg polaritons, gems turned out to be better than artificial crystals

(ORDO NEWS) — Using cuprous oxide crystals, scientists have obtained Rydberg polaritons of record parameters. These quasiparticles can become the basis of quantum computers, however, crystals of the required quality turned out to be possible to find only in nature. At first glance, copper oxide (I) Cu 2 O, or cuprous oxide, is a fairly common substance, especially familiar to those who deal with electricity. It is formed during the…
