Non-Quantum Photon Detector?

What is a non-quantum "classical" photon detector? It seems to me that the detection of any photon is a quantum event...unavoidably.

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?

Relax. A few pounds would yield a few billion devices per person.

Any conventional photodiode is a "classical" detector.

I'm not sure what it means for them to be called the 'first successful quantum technology company'?

Do they have sales?

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?

By entangling thousands of photons simultaneously, they become visible to any classical detector, which includes both photo-detectors and the naked eye.
