Once a proof-of-concept exists, scaling it up is conceivable. Computers used to have kilobytes of RAM, now some have terabytes. Digital cameras used to have sub-megapixel resolution, now some are measured in gigapixels.

- daniel-cussen 4y agoMmm...but scaling up is not the same in photonics as it is in digital. Everyone thinks of scaling in terms of digital, like Alan Turing, von Neumann, and later Moore talked about, if you have an amplifier you can amplify it with another amplifier, so as long as it's totally digital the signals can be manipulated at arbitrarily small scales. Not true for analog or photons or quantum, there's weird caveats and they're not well researched, this scaling works only for digital.
- haswell 4y agoSure, our existing understanding and models for scale may not directly apply. That doesn’t limit the creation of new models and new understanding. Just because scaling might be different doesn’t mean it’s impossible. Our existing models did not exist at some point in the past.
