Cheaper than the cheapest QRNG sounds like a lot of wiggle room.
Less than several $1000US ?
OTOH LEDs are quite complex to fabricate and yet mass production has brought their prices down hugely.
Like the idea.
Hate the application.
Quantum random number generators aren't new, but one small enough to provide practical security for Internet of Things applications is interesting. That's what South Korean telco SK Telecom reckons its boffins have created, embedding a full quantum random number generator (QRNG) in a 5x5mm chip. The company's pitch is that …
Doesn't need a fake chip. The real chip will have a debug mode that replaces the Q bits with zero for production testing etc. All the three letter agency has to do is activate the debug mode.
Nobody takes out debug-mode just in case it breaks something and you have no means of debugging.

Don't worry, this is one game that Debian can play too. That meant only 32,768 possible seed values for the RNG and it was unnoticed for nearly 18 months.
I'm guessing that this patent application (published 6 July 2017) might be something to do with it
Quantum Random Number Generators can be very cheap and anyone can build one.
