Wall Observer BTC/USD - Bitcoin price movement tracking & discussion

[sniveling]

This talks about bits.  It is my understanding that qbits are significantly different from bits.  Sorry that I can't illuminate further.

"...until computers are built from something other than matter..."

We can get semantically cute and argue both sides, but in my book a quantum computer passes this definition.

Armchair scientist here, but - the differentiating criterion of a quantum computer is the existence of these chained qbits.
A problem with 2^8 possibilities has 256 solutions. Our normal computers take that O(n^2) problem and solves it by traversing all n^2 solutions.
Computer science demonstrates we can solve big-O problems in less than the brute force number of times. However, we cannot reduce Big-O-COMPLEX problems into a problem set that is small enough for a regular computer to solve.

A quantum computer would look at this problem and say, okay, I need 8 qbits. One to store each of the two possible outcomes for each of the 8 possibilities.
Having those, the solution is O(1) - it is already solved. Each qbit holds BOTH states, so a 2^8 problem requires 8 qbits. A 2^512 problem requires 512 qbits and it is solved. A standard computer could never solve it.

The writer of that quote understood that notion. He understood that a fundamentally different process must occur than the one we use today to make the next evolutionary leap in processing.

I would argue that since the 'core' of the machine relies not on a measurement that is physical, but on the underpinnings of quantum theory which rather fly in the face of matter...that the quote is quite correct.

I disagree. I think you give the writer too much credit. A natural reading of what's written is that it is impossible to break Bitcoins algo in this universe.

Quantum mechanics is very much part of this universe.

Disclaimer: Not even an armchair scientist.

"... until computers are built from something other than matter and occupy something other than space".

Qbits exploit weird quantum effects like one atom being able to be in two places at the same time. The qbits in a quantum computer occupy something strange that might be considered "other than space". Existing in two places at the same time is a departure from the standard three dimensions of space we all know.

Wow. Zany wall fight at Finex. 3k bidwall staring down a 1.5k askwall.

And like that they're gone. Entertaining or what?

Edit: now it's 3 separate 1k bidwalls. 

[Alley]

1k market buy on finex.  Price didn't budge.

[AZwarel]

There was a kind of meh interlude in Eurovision 2nd semi-final live just an hour ago. They used a "funny sketch" saying something like this in the sketch: "..it costed around 3 billion dollars back than, which is about 500k bitcoins today.." (actually not accurate, but that is not the point :-P).

LOL. Mainstreaming slowly :-)))

Check it out^^

[hd060053]

sell walls are gone again. 5500 to 470.

[JimboToronto]

sell walls are gone again. 5500 to 470.

Those three 1k bidwalls just vanished too.

The whales are frolicking.

Edit: now it's a 4k bidwall. LOL

[JimboToronto]

Damn. I have to get out to the butcher shop before it's too late for them to cut me something.

I hope I don't miss the show.

It's not magic, it's well known physics. And the computers themselves are built from common materials. It's simply taking more advantage of the quirks of quantum mechanics. Regular computers are based on quantum mechanics as well. Regular computers rely on quantum states as well. It hasn't ejected them from space and time.

Anyhew, your interpretation is contradicted by the bit at the end:

"Bitcoin - Your money is secured by the laws of the universe"

I'm not saying we can't read qc into it after the fact, just that I think Chainsaw was being a bit generous with regards to the original intentions of the author.

This is the big one! You hear that, Elizabeth? I'm coming to join you!

There's no way this is real; did people actually pay money for this on the darknet?  Do people actually believe this / take it as 'proof' that satoshi is one person, let alone a japanese guy (the dude in the picture is not japanese...)?

[JayJuanGee]

It's called grid trading. I do it with a bot on eth_btc. And I can tell you that in two sentences, or three if you count this one.

You can call it whatever you want, including uncle bob, if you chose not to explain specifics, which had included applying practice to theory and also responding to issues/questions raised by someone else on a forum.

And, by the way, you are welcome.

shorts capitulating ... multiple failed sell down attempts are getting too costly, they'll retreat higher shortly.

Would this do?



(it might need a little TLC, maybe a new set of plugs and an oil change, but it's in pretty good shape)

THis one is more fitting

Sure, I understand that kids like you cannot resist your own excitement and to superficially chime in regarding topics you barely understand.

"... until computers are built from something other than matter and occupy something other than space".

The qbits in a quantum computer occupy something strange that might be considered "other than space". Existing in two places at the same time is a departure from the standard three dimensions of space we all know.

Photons, which can be used for qubits, are massless particles and have no volume. Hence, I assume, where the "built from something other than matter and occupy something other than space" comes from. However, you can implement quantum computers with particles which do have mass and volume, so his point is invalid.
