EET: Denmark researchers claim breakthrough component prototype for quantum computing #tech ^BH

The diode-like action of their first breakthrough device could also be useful in spintronics applications, where digital data is recorded on the up- or down-spin of a singe electron. But when asked, the researchers told me their goal was a 'QC: "We have two possibilities: encoding the qubit either in the spin of the emitter (matter) or in the propagation path of the photon (light). Generally both are required in order to construct quantum logic. This is why we need to control the light-matter interface." Dr. Lodahl also added: "Single photons can be used to construct quantum simulators that emulate a complex quantum system that cannot be properly described on a classical computer. This could eventually tackle problems in chemistry or material science where detailed insight is often limited by the fact that these systems are inherently quantum and therefore intractable on c...
