General Guidelines
---- Nous avons besoin d'un traduction français!
Some Basics
1. Under Board "Frequently Asked Questions" (FAQs) there are 3 sections dealing with General Forum Usage, User Profile Features, and Reading and Posting Messages. These deal with everything from Avatars to Your Notifications. Most general technical questions are covered there. Here is a link to the FAQs. https://forum.chesstalk.com/help
2. Consider using the SEARCH button if you are looking for information. You may find your question has already been answered in a previous thread.
3. If you've looked for an answer to a question, and not found one, then you should consider asking your question in a new thread. For example, there have already been questions and discussion regarding: how to do chess diagrams (FENs); crosstables that line up properly; and the numerous little “glitches” that every new site will have.
4. Read pinned or sticky threads, like this one, if they look important. This applies especially to newcomers.
5. Read the thread you're posting in before you post. There are a variety of ways to look at a thread. These are covered under “Display Modes”.
6. Thread titles: please provide some details in your thread title. This is useful for a number of reasons. It helps ChessTalk members to quickly skim the threads. It prevents duplication of threads. And so on.
7. Unnecessary thread proliferation (e.g., deliberately creating a new thread that duplicates existing discussion) is discouraged. Look to see if a thread on your topic may have already been started and, if so, consider adding your contribution to the pre-existing thread. However, starting new threads to explore side-issues that are not relevant to the original subject is strongly encouraged. A single thread on the Canadian Open, with hundreds of posts on multiple sub-topics, is no better than a dozen threads on the Open covering only a few topics. Use your good judgment when starting a new thread.
8. If and/or when sub-forums are created, please make sure to create threads in the proper place.
Debate
9. Give an opinion and back it up with a reason. Throwaway comments such as "Game X pwnz because my friend and I think so!" could be considered pointless at best, and inflammatory at worst.
10. Try to give your own opinions, not simply those copied and pasted from reviews or opinions of your friends.
Unacceptable behavior and warnings
11. In registering here at ChessTalk please note that the same or similar rules apply here as applied at the previous Boardhost message board. In particular, the following content is not permitted to appear in any messages:
* Racism
* Hatred
* Harassment
* Adult content
* Obscene material
* Nudity or pornography
* Material that infringes intellectual property or other proprietary rights of any party
* Material the posting of which is tortious or violates a contractual or fiduciary obligation you or we owe to another party
* Piracy, hacking, viruses, worms, or warez
* Spam
* Any illegal content
* unapproved Commercial banner advertisements or revenue-generating links
* Any link to or any images from a site containing any material outlined in these restrictions
* Any material deemed offensive or inappropriate by the Board staff
12. Users are welcome to challenge other points of view and opinions, but should do so respectfully. Personal attacks on others will not be tolerated. Posts and threads with unacceptable content can be closed or deleted altogether. Furthermore, a range of sanctions are possible - from a simple warning to a temporary or even a permanent banning from ChessTalk.
Helping to Moderate
13. 'Report' links (an exclamation mark inside a triangle) can be found in many places throughout the board. These links allow users to alert the board staff to anything which is offensive, objectionable or illegal. Please consider using this feature if the need arises.
Advice for free
14. You should exercise the same caution with Private Messages as you would with any public posting.
15. Have fun!

Re: CCC Discusses Chess - Posts of Interest -What Is The Future Of Chess?
The Iranian (or some other) government could already conceivably cause havoc enough using cyber warfare/espionage, not to mention the possibility of disruption of the electrical grid or computer-based technology through an electro-magnetic pulse, or simply by unusual solar activity. Similarly, decades ago, it was later revealed, a Soviet satelite was temporarily blinded/confused by the sun, almost resulting in a missile launch but for an officer who refused to follow protocol.

And remember: Paul Beckwith is still out there. Even with quantum computing, we still have climate change to worry about.
Not really as there has been no warming in 16 years according to Paul's friends on the receiving end of those leaked emails... Maybe quantum computing will allow them to come up with climate models that actually model reality and not chicken little fantasies.

I haven't even partly checked the semi-private hell that is the Climate Change thread in months, but I pretty much gave up sitting on the fence ages ago, after Climategate. Every time warming in the Arctic is reported in the news, a reasonable-sounding *denier* explains it later on, with weather-related reasons. Last I heard, apparently Antarctic ice was expanding.
There are threats to our survival far more real, and possibly looming, than Climate change.

Yes codebreaking is a key application, and yes the sudden appearance of a working Iranian quantum computer would cause havoc, but you overrate the impact just as much as Y2K was overrated. Y2K would have been a serious problem if not for proactive fixing but it would never have been a disaster. Same here.
So you are saying if nothing had been done for the Y2K problem, it "would have been a serious problem" but "would not have been a disaster". To back that up, you first of all need to define a "serious problem" versus a "disaster". And then you'd have to outline exactly what you think would have happened, backing that up with... something, I don't even know what.
If the Iranians unleashed quantum decryption on the world, what kind of "havoc" do you foresee and how would the world's banks and credit card companies overcome it?
Before generally usable quantum-based decryption is available, quantum encoding will be here, and that code isn't breakable. The important stuff will be resecured using that technology, and the world will carry on.
That's one possibility. But if decryption comes first, from someone who is hell-bent on destroying Western civilization, and that civilization hasn't got the technology to have quantum encoding, that's a totally different scenario that would unravel the entire world economy. All the world's fiat currencies would instantly revert to their true value (toilet paper), and actual physical resources would be the only thing left for the world to fight over.

Kevin: "Last I heard, apparently Antarctic ice was expanding." Climate change disaster might not be real, but this is certainly false, unless you're talking about October having more ice than September because, duh.

Actually since this is an opinion thread, I merely need to give an opinion and reasons. The reality is too complex for any "proof". Here's my reasons: Remember all the doomsday scenarios back then and all the "it's nothing" counter-arguments. In the end, "it's nothing" won, and the counterfactual scenario is not known. But most systems didn't require extensive correction, certainly not power systems, and if errors did arise some electronic transfer might have halted a few days until it was corrected.

1) Working quantum computers is harder than quantum encryption because the former requires a programmable computer and the latter only quantum gates.
2) Odds of Iran getting any of this ahead of everyone is minimal.
3) If they did get it and misused it, their Internet would be throttled by whatever means necessary.
4) There are methods of security besides encryption, that can be used to inhibit bad users.
5) To log into a site, you need a password. The password can't be gotten randomly, or using quantum methods on a digital line.
6) If you could intercept the wire you could intercept encrypted data and decode it, but it won't be easy to get that data in the first place.
7) If all the above went wrong, authorities would take physical measures to limit access to the critical data. Trade would slow down, but "revert to paper value" wouldn't be the end.

Ok, in these matters it seems all we can do is give opinion, and your opinion may be correct, we can't really know.
I just use Iran as one example, it could just as easily be China or any non-Western power that is hostile to Western civilization. What I'm postulating is that we are so focused right now on Iranian nuclear weapon capability, it seems no attention is being paid to any research that might be underway anywhere in the world for quantum computing, whether it's an actual computer or the quantum gates you talk about for encryption (and if that's all that's needed for encryption, is it also all that's needed for decryption of the current (non-quantum) encryption methods?).
I still see quantum computing as a double-edged sword. Just to assume that something is very unlikely is not good enough in this modern world. That was the lesson of 9/11.

Ever hear of WireShark? Being used all around the world to grab data off the wire, anyone can do it.
The world economy is based on the free flow of data, despite the availability and use of tools like WireShark. Encryption is a necessary component of the functioning economy. Break encryption and you break the world economy.
Iran or China or whomever needn't worry about their Internet being throttled. I am sure they have people outside their national boundaries who will not be impeded by that.

I've seen that report too. Antarctic means southern hemisphere. October will have less sea ice in that part of the world because it is mid-spring versus early spring in September.
On the whole quantum doomsday scenario there were recent rumblings out of the U.S. military where they indicated that they did not rule out military options in the event of cyberattacks. I suspect that a quantum computer won't survive a direct military attack. The net effect of the cyberwars has been that the U.S. and the rest of the west including Israel have become more aggressive in this area.

Many banks and governmenta already use quantum cryptography to protect their data. We must not forget that while quantum computers aren't strong enough for now, one could intercept data (which is easy) and then simply keep it until quantum computers are able to decrypt it. The decryption would probably be 10 years late, but it could still be very useful.
PS. I find quite ironic to see climate change denial posts on a topic about science. Will we also have the chance to see posts about how the world was created 3000 years ago? :)

Nobody claims the world was created 3000 years ago. I believe that they usually say it was 6000 years ago.

Do you have any source for the claim that many banks and governments already use quantum cryptography? Or what that means, at least? I am not aware of any working quantum computers other than lab demonstrations that seem to flip "bits" from one state to another - that is rather far from a working computer.

I'm surprised. I thought quantum cryptography wouldn't be available for a couple years, but there it is. Proves what I was saying though about it being easier than breaking conventional crytographic codes.
I expect groups are capturing and storing current data for future decoding. There is a limit to that though as the amount of data transferred exceeds the capacity to store it.

Encryption doesn't require a computer though. It merely requires the creation of bits of matter in a quantum entangled state.
