What caught my eyes is "up to 10 billion super cooled rare-earth ions".
Mining of rare-earth metals seems to be inevitable for the next generation technological advancement. As most people have heard, mining of rare-earth metals causes an exceptional pollution. Any short term solution to the issue? Where else can we dig out more rare-earth metal?
If "any conventional photodiode" is a "classical" detector, then all photodiode detectors must also be quantum detectors, since they only work through quantum processes. My question remains unanswered: What is a non-quantum detector?
Yes, ID Quantique has customers, although not as many as they would like (the recession hit the financial community just as they were getting started which nixed their original business model, which was to get banks as customers for securing financial transactions). However, they still have more customers that the second successful quantum technology company, D-Wave (which only has Google, NASA and Lockheed).
Is this simply doping of a direct bandgap material (not so uncommon) or some fancy smancy new thing that will ultimately lead to teleportation, a la Star Trek! Seems like a bit more info would be helpful. Anyone got a link to point to a bit more detail?
