the whole point is that quantum mechanics is that it can't be easily understood. (which is funny because I started to understand after a bit of research, none of which was at the beginner level) (at least a functioning understanding of it.)

It's not the sound guy's fault that the mic is a pile of shit. They often have to work with the best of what's available...

tbirdparis too bad it's a fantasy because it's physics is wrong in the 1st place.

We had Wireless Mics that worked great, then the FCC sold the spectrum....

It happens when you try to send a 600Mhz signal across a room full of cell phones instead of placing the receiver right behind the presenter backstage, and using timers or an assistant to track battery levels.

She mentioned 'Total Beginners'... What is before that?

@@krakrakakakakahah241 nerd? Lol

“Novice” which is what I am.

Dunce, a class with it's own cap...:D

I've yet to find someone explain quantum computing in a meaningful/understandable way. Everybody seems to make too big jumps and didn't manage to find the right metaphors.

the way I understand it (which is based on videos by veritasium), the essential power of a quantum computer is that you can consider many states simultaneously. in order to make it work, however, your algorithm must be able to produce an end state that is readable. As far as I understand, that means the information that you read out at the end can't have superpositions. (this is probably still extremely simplified). This means that quantum computers require more complex algorithm design to be useful as far as I understand.

This video isn't bad, I'd say good, but the subject is complex enough to not allow a ground-up explanation in a few minutes. You always have to assume that the audience has some basic understanding, e.g. they understand English language. It's just in case of quantum computing you pretty much have to assume the listeners have a (very rudimentary) basic grasp on quantum mechanics and linear algebra. Here's an example: if you're a programmer, or at least understand basic scripting, you'll appreciate how hard it is to explain how C++ is different from Java to a 90 y.o. grandma (or 9 y.o. boy) who never had any interest in computers and doesn't know (or cares to know) what programming is. Your 5-minute explanation will probably be either misleading, or incomprehensible. IMHO.

feastures You perfectly summarize the issues that I also have with these "educational" videos.

There is a very good reason you do not understand this . . . QCs, the way she described, is not functional. Adding more ambiguity into logic does not equate to solving harder math problems. Example of typical logical computers: 1 + 2 = 3 Example of QC computing: A + B = C Which one of these computers provides an answer that is useful? The other huge drawback with QCs (as described) is that QC theory says that A + B might equal C. Sometimes it equals C. Sometimes it doesn't equal C. So, not only do we add ambiguity with QCs, we also add more error. It is so ridiculous that these claims made by QC "scientists" are going unchallenged.

Come to me boi I'm in hyperposition.

make sure to wash afterwards

No you aren't, and yes you are.

XD

No shit huh? Lol

Tech people always have problems with basic audio equipment. That is a given.

The people who build the quantum computers are probably not the ones who record, edit and upload them to youtube.

It's her necklace... NBD.

Well yes, but you have to consider that she's giving a talk to a bunch of people who most likely have no idea what quantum computing is, or have any idea of how quantum mechanics can be utilized to create meaningful speedups. The groundwork of quantum computing is actually quite complicated, and involves lots of linear algebra, something not every person is automatically familiar with. So while yes, it is basic, to say that the IBM team has not yet achieved anything worthwhile with a quantum processor is kinda naive, as in order to explain the worthwhile things she'd have to talk through a number of different concepts that would most likely only confuse the target audience.

HellTube yes, true...

There more sinister things going on behind these quantum computers, just like 5G it's not needed to speed up internet, we can send a msg across the earth in a second, 5g is part of agenda 21, lockstep scenario etc. Depopulation through vaccines

Just like Elon Musk when goin on stage, talks abouts future of marvellous just to raise the stocks and people buy and then asking gov more taxes to subsidide his bussiness.

Had to scroll down to check if anyone noticed that.

On a round table with people, all that matters is if someone is sitting next to someone else. The number of combinations is much much lower. For example, with 4 people, it's just 3 combinations.

in this particular case, it's a real table in a real room, so its not just the circular permutation, because which way you are oriented matters. (ie who has their back to the head table, etc)

Yeah I caught that one too. :-)

Exactly dude :P

True... Unfortunately the original video's audio is screwed. But the talk was so appealing that I just had to repost.

thank you

Scientists are currently working on a way to record sound without significant distortion. Quantum computing is being put on the back burner for now.

Travelling With Gazz nah the sound guy just put the mic on her jacket in a bad spot and didn’t take into account that people move around and she has jangly jewelry on

i am watching this video alone and it's 4:30 am here...the audio cracks scared me .. it's like some demon trying to communicate

I Agree! From Dan

Nope. I cringed every time she said "Quantum Computer". There's no such thing. You can have a "Quantum Co-Processor" but a single, stand-alone quantum computer, no. Quantum processing is and always will be a complement (an add-on) to standard computing.

SpudHead, while your technical distinction is interesting, it's likely anyone who refers to "quantum computers" will mean any computer with classic processors with quantum coprocessors. It's also the dream that these coprocessors be integrated into classic computer chips like the old math coprocessors, then later gpus. If technology emerges such that quantum effects can be cheaply integrated into hardware chips, there's no fundamental limit saying that the same techniques used to optimize classic machine-code operations at the chip hardware level cannot be replaced by quantum integrations that are faster. At that point, the quantum addition to the term is no longer a coprocessor. I imagine in those days every computer will be a quantum computer and you can drop the "quantum" prefix altogether.

Right?

Maybe good. They Wouldnt buy all the Graphics Cards.

So the quantum computer is going to compute hashes faster and that is going to increase the difficulty. This cycle continues and computations become harder and harder. Is it going to become an infinitely hard problem or will all the coins be mined out?

you would simply make the algorithm harder and harder untill the quantum computer isnt able to calculate efficiently... A quantum computer doesnt have an infinit computation capacity

RMF. Yeah, but if you are the only one for a year that even has a chance of calculating then it's worth.

Why not just simply a crypto solver? Much easier cash. Got an address with cash? K, just solve it and get the private keys. Then just transfer the coins to your own quantum safe address. When it's worth millions, it stops being theft. Then it's just business. ^^

Those are called 'parameters' and you would input those into the algorithm for it to produce a result. There are infinite parameters. Maybe you'd wanna have all the people sitting next to another person who has traveled to the same countries. That's just one example of a problem you would want to solve from simulating that scenario. Or maybe you would want to have it find out which combinations of seaters would spell out words using the first letter of each persons name. There are seriously millions of problems you could derive for it to solve using that one simulation. People just aren't smart enough to make use of the quantum computing power.

If you could, it will be more valuable than any amount of bitcoins you can ever imagine.

LOL if you could do that you wouldn't need bit coins. But that's just the kind of thinking we need. There must be some way I can exploit this for my own use! Is a great motivator!

there would be no encryption if quantum computers start working properly.. there are in early stage so mine as many as u can now..

Yes/no

She does mention on the first the day the grain of rice would be 1 which is 2^0. So the 64 days would be 0-63, that means the last day would be 2^63.

wrong

Maybe she took small rice...

Where do the 2^-27 m³ come from?! 2mm³ are 2E-09m³...

Ben, you've got your rice powers wrong

Too Funny!!!

At last someone who understands the Quantum Effect....this is not the same Earth.

And I couldn't handle the ego... right!

Was looking for this :')

That's only true if you assume that if you're able to "rotate" one permutation of people to another, the two belong to the same "permutation class".

me too, was thinking the same thing

So, only ~360k permutations?

that's true

bitcoin, sha-256 is essentially qsafe. Unless we're talking about machines with 128+ qubits.

NOPE, Bitcoin is not safe, IOTA perhaps

your mom...

Quantum computer wins. Some emotional idiot investor located anywhere in the world can destroy the value of Bitcoin on any day of any week.

A cubit is 18 inches long. 5 QUBITS is miles bigger.

kimbal summers I know that you're trying to emphasize the power of exponential growth, but the reality is that 2^5 is just a mere 32 effective binary bits. It's still a super small number.

Are you sure about that? :D I thought the 5 Qubit were like all states of the 5 binary bit at the same time, so 32 different combinations. Like if you have the seating problem, you can seat 5 people with 5 qubit, because all 32 states are "calculated" at the same time and only the best combinations gets amplified

no, a qubit has 4 different states, 00, 11 and a possibility to float between (01,11,10,11)

8:57A little here a little there beware neuralink out there lurking at short and long distance quantum computers quantum physics the power exerted by cern assisted by five g and starlink passing an emp like a touchdown from a QB simultaneously mutating algorithms Ask any emt in how long the brain begins to die with no pulse inside it’s not hard to see if the world had a blackout like India in two thousand twelve and and in the United States north East in two thousand three we don’t get up like powerlines cables and electrical appliances end game for you and me

kiyallen Woody got me interested in further research into this subject.

Hello 4 years ago person, I'm 4 years later person. Things are great now. We have flying cars and shiet. Best regards,

Good catch; another example to help visualize: square nr.2 has "2 to the power of 1" grains.

That’s true but it’s 2^64 together with all the rice from the other 63 days. Another thing that is wrong is that the amount of rice not corresponds to just 1 Mount Everest but to over 1 million! (see calculation made by Stewie Griffin in this thread).

It is.

First questions over 4:45 A bit is like a coin heads or tails (either 1 OR 0), say you want heads, you look at the coin and see its tails so you flip it over to heads to find the “solution”, this took you two trials to finally get to the solution, you looked at it and saw tails, flipped and looked at it again to see heads A qubit is in a state of superposition which makes it 1 AND 0(imagine a coin endlessly spinning on a table, looking at it from the level of the table it looks like both heads and tails), again say you want heads, looking at the coin you get your heads right as you look at the coin, you do not need to flip it, so this takes only one trial Relate this to the whole mathy side your asking about, With bits you go through solutions one by one, say 5 bits so 2^(5) = 32 solutions, trial this out one by one, 0 0 0 0 0, 1 0 0 0 0, etc etc till you find the solution 1 1 1 1 1 (for example) Qubits you go through ALL solutions at once, say 5 bits again so 2^(5) = 32 solutions, solution is 1 1 1 1 1 (for example) Basically qubits are faster, waay faster Second questions over 5:00 Pretty much answered above, except ur very last question which I’m not quite following.

lets say you had the 10 dinner guests, all of who is happiest given certain arbitrary criteria; person a wants to be next to person d, person f hates person i, etc.. lets say when you position everyone, it runs through a calculation to get a final happiness score. to brute force solve it with a modern, classic computer and check every possible configuration, you would have to test 10! (10*9...*2) possible configurations in order to say beyond a shadow of a doubt this is the best way to seat everyone to get the highest happiness level possible, or 3,628,800 possibilities. a quantum computer with 10 qbits can position each person as a variable, and test all positions simultaneously, arriving at the perfect solution on the first pass through.

Bitcoin will be dead in a few years. A quantum computer right now would end it almost immediately. And at a loss of roughly 50 Bitcoins/satoshi's per year due to people dying and the currency being unable to be reclaimed will be the ultimate death of Bitcoin. Only an idiot does bitcoin.

Lord Krythic maybe if they start now. People who invested just a few years ago have become millionaires from it. But before quantum computing kills it, if a few individuals can get their hands on a quantum computer programmed to mine, they'll make decent profit

Use quantum computer to mine... bit coin can evolve, how? leave this part for the quantum computer engineers to solve ;)

AwesomeGuy hehehe

Lord Krythic the first person to demonstrate quantum computers can crack encryption will inherit at a minimum all of satoshi's bitcoin (1mil+). Have at it dude.
