clock couple device entangled essential external fabricated generation latter light means ordinary produces quantum secondly similar trigger
The device is important for a couple of reasons. Firstly, it's fabricated in a similar way to an ordinary semiconductor light emitter, and secondly it produces entangled photons on demand. The latter means we can trigger the generation of entangled photons with an external clock signal, essential for many applications in quantum computing.
challenges effect emission expect four production reason replicate room seen three
There's no reason, in theory, why we can't replicate this effect at room temperature, and we've already seen emission at 1,300 nanometers where telecommunications lasers work. There are challenges still to be overcome, and I'd expect to see this in production in three to four years.
