Yes. I know the rules. I was a member of the 802.11 and 802.16 working groups and Bluetooth sig that developed these unlicensed band protocols and I've developed WiFi, WiMax and Bluetooth products. Having a protocol that bangs out a base station frame structure like LTE which splats on the band and has no backoff for other users of the band isn't part 15 compliant without being at a power that isn't useful for high speed data communications.

So you're saying it's an ITU/3GPP/esqu spec for a protocol and I'm not allowed to deploy it in an unlicensed band, but carriers who already have exclusive access to licensed spectrum are?

Could you explain how the LTE frame structure is compatible with part 15? I don't quite see it.

It's a refrigeration problem.
You need to get stuff very cold to dampen down the noise (other things entangling with your qbits).

Making things cold takes energy. The lower the entropy in the qbits, the higher the energy that you blow in the refrigeration. Overall entropy will increase. So you might be able to equate the energy in the heat of serial computation of an O(2^n) problem to the energy spent cooling a circuit cold enough to solve an O(2^n) problem in parallel with magic quantum behaviors. Unfortunately in the parallel case you have to blow that energy all at the same time. If the serial case looks like it would need enough energy to boil all the oceans (about O(2^128)) then the parallel case might boil them all at once. You might want to get inland.

Say goodbye to asymmetric encryption.
Symmetric like AES can still survive quantum attacks with a doubling of key length. But all the current asymmetric algorithms are in peril once quantum computers exist.

Say hello to quantum encryption to replace some uses of asymmetric algorithms (which are often only used to exchange keys for symmetric algorithms).

The real danger is to public-private key signature algorithms (such as those used to sign certificates). At some point these may need to change to use proof-of-work (e.g., bitcoin) style authentication or other cost prohibitive measures...

No, there are quantum secure public key algorithms. They are around 2X less efficient on key size than ECC. So it's not a huge problem.

The selling point of things like lattice crypto (e.g. NTRU) is that it is quantum attack secure.

But don't worry. They aren't going to build a working quantum computer that can factor large numbers or solve the DLP over elliptic curves. They can't make things that cold.

Comment Re:Current research in cold fusion (Score 1) 144

Sounds interesting. Do they have any estimate of the maximum rate of fusion? I can well imagine cold fusion being a reality that happens, but never produces enough energy to bother with.

And, of course, any limits they estimated at this time would be subject to improvement..

Not having a lot of capability of investing in something rather speculative, I'm going to consider this something more interesting than useful until someone with plausible knowledge says otherwise. (And I still won't be investing, but then I'll follow it with more interest.)

P.S.: SRI has, in the past, put effort into some rather questionable research. They hire a lot of people and some of them aren't above inflating their results. But they also do lots of really excellent work. You just need to remember that some of their researchers aren't exactly indifferent about the success of their research.

Nahh. Leave open the possibility that he's honest and really has something. But if he's incapable of sharing it, for whatever reason, then it's worthless to anyone else.

Remember, in the really early days of crystal radios there were frequently people who could get their set working, but couldn't help anyone else to do so. So leave slack to allow this to be what's happening here. Of course, it's still worthless to anyone else.
