Anybody remember the stories of when computers were freaking huge, like, building size and how the nerds of the time started coding games on those things? I wonder when we'll start hearing anecdotes about how the researchers working on quantum computers started writing games for them. I know they are planning on using them for complex simulations, at least initially. Maybe they will just use them to perform the simulation calculations for the game universe or something along those lines and then have that feed into a secondary standard machine that runs the rest of the game. I don't know, but I can almost guarantee that _someone_ is going to to do it at some point. ;) Just wait until we hear that someone ran Doom on one. heheheh :P Or, of course the perennial favorite, Crysis.

The group that did the Bob and Alice work actually presented at my local Murdock conference... cool. I liked it better with all the math though lol.

Can you take advantage of quantum entanglement to send messages over long distances instantaneously? If so, that would make setting up a network trivial because all you have to do is send out some machines with entangled transmit/receive particles and avoid laying down a bunch of fiber optic cables.

Quantum internet? So memes in 7D?

Isn’t this how the original internet started? I remember working in large FREEZING computer rooms when I first started working, many years ago (lets just say more than 30 yrs) and everything was so top secret then too. Now look where we’ve come…all three of my kids have their own computer station set up with video systems in their “play” room that doesn’t require more than a ceiling fan because they want it on! Now, I am the one looking forward to the QUANTUM INTERNET and sure hope it’s really NOT that far off! I’ve already hit mid life, I haven’t got another 50 yrs to wait for it…I am ready to play with it NOW! Just imagine all the interesting things we could do without having to buy a FIREWALL and then still worring about getting hacked like it has happened to often lately! I am rooting for you - probably your biggest fan..in the public anyway! I love 10 01, they’re our best friends! Remember there are only two kinds of people in this world!

Stella Nova A strange game. The only winning move is not to play.

how can you harness a superposition? can anyone explain how a qubit being both a 1 and 0 simultaneously can provide the decisive output of a 1 or a 0? or does the value stick at one or the other once its measured and the superposition just allows for faster alternation between the 2?

Can someone help me with understanding quantum computing, from my understanding, the state of having both a 1 and a zero is when it is unobserved, and when observed it becomes a 1 or a 0, since you need to observe things when looking up information, how is it useful? I think that perhaps for random number generation but not for info storage

1:17 Missed opportunity to say "Tip of the Heisenberg."

At 2:42 you state that there is a key share. Actually how encryption works at this time is by (following the analogy) sharing padlocks so a third-party listener can not decrypt it (the keys are kept private). Just to be clear I'm not saying quantum computing won't be more secure, of course it will. Just stating a miss conception on how encryption at this point in time works. You guys are great!

how do you read the information if its all at once? how do you get message decypted if its key is right and wrong at the same time?

For reference this is one of the better videos. I like the videos that make you want to go out and learn more and create a vested interest in science, but when I see videos like "why don't we throw our trash in volcanoes" or "why does getting kicked in the groin hurt so much" I just want to turn my computer off.

Love the new host! Dictation and enthusiasm is spot-on. Shirt too :D

Theoretically you can send a probe out of the solar system with 2 entangled particles one on board the probe and one on Earth. Sending commands to the probe using the particle's spin would be instantaneous and the connection will always be 100% so long the probe still has power.

@SciShow can you magnetize Erbium?

That isn't quite how quantum computing would work. Part of the problem is the whole 'how many classical bits you would need to properly simulate N qubits'. It doesn't actually mean N qubits would give you the computing power of that many bits though. So it doesn't actually scale in the exponential style that gets tossed around. A quantum computer would actually be slower than a classical computer for some tasks practically. A good list of what algorithm would get a quantum speed up can be found here; math.nist.gov/quantum/zoo/ We also then fall into the issue of error and how to handle that, with the more popular approaches being topological error detection/correction (like the Surface Code). This leads to needing many physical qubits in order to have a logical qubit with sufficiently low error rate to get any useful computations done. The Quantum Key Distribution (QKD) explanation was pretty accurate.

It's not that they are spinning "up and down," electrons in a state of superposition are considered to exist in all possible states, until they've been perceived. It's like Shrodingers cat, theoretically the cats both dead and alive, but really it's just one or the other until you open the box and find out what it really is. The electron isn't physically in two states at once, you just have an indetermination of it's status. If you think about it with superposed location instead of spin, the electron would literally destroy the laws of conservation because 1 would become infinite without any loss of energy, as the superposition would require the electron to exist in all possible positions at the same time. Quantum mechanics can get kinda metaphysical, which is where I think a lot of people get confused. Everything is about perception which is subjective, and that's if there's even anything there at all. It's kinda fun.

Omg I love these videos

I love how everything that use quantum mechanics, is named quantum [product]. I can't wait for my quantum computer, I'll just need a quantum keyboard, quantum mice and of course the quantum desk to put everything on.

We are ways away from it. This is a good incremental step towards the storage problem. But quantum internet is bit of a stretch at this time.

"Quantum repeater" contradicts with "You can't do Man-in-the-middle attack to a quantum network."

Sounds very promising for the future,I assume would be much faster and secure

How can you encrypt information when any interaction causes a collapse of the wave function?

How do you know if someone picked up your information when you send it to other people?

"Captain, Quantum Iceberg ahead...but also off to one side at the same time?"

A tangent but related, I don't know enough to say if this is possible but wouldn't it just be easier to use intagled pairs of particles and use the properties from one to encrpt the data and use the properties perceived on the intagled particle on the other side to decrypt? I know that iyou can't transfer information via that method but the data should still work for a key as far as I know, the only thing I'm not sure about is if they can be measured the the same data without interfering with it at the same time, would be pointless if you act of encrypting the data destroyed the key for both sides before it was even received

And once we will finally get the non-deterministic Turing Machine 👍😉!! dope xD

I've never really understood electron spin. It can be either "up" or "down", but doesn't whch one it is depend on what angle you're looking at it from? Do a video explaining why it doesn't.

How about particle entanglement to transmit data?

A small even though very hard and complex step for the engineers but a giant leap for mankind. Then they can simultaneously publish the pictures of their cats from four mutually exclusive perspectives on the social media page at a rapid pace and in a secure way!

If you have a light detector and it graphs light energy absorbed as a function of time, you can see something a line, a continuous smooth line apparently. And that's the classical understanding, light energy to be smooth energy and a wave. But then Plank calculated that light is absorbed in chunks depending on the frequency, Ep=h*f. So actually if you have a good enough detector, zoom in on that graph and you'll see it looks like a step, and it's fixed step, because you can absorb light in chunks, let's say we have a scale 1 unit of energy per red light photon which is not true in reality. But the thing is, on that graph you would see that your energy is either 1, 2, 3, 10, 20, 22 etc. never 1.2, 1.4, 2.5, so never in between a chunk of energy, this is why photos are views as particles, and then when you have something like the slit experiment, it acts as a wave, and that's why it's quantum mechanics, it's a wave/particle system or whatever. Btw if anyone wants to study this, go to khan academy, it's free

Optical quantum internet is look less and less like the best option. As it stands (at least in my growing understanding) data transmission over quantum entanglement is showing more and more promise. The real hurdle (at this stage at least) is how to get a quantum qbit internet to interact with existing infrastructure, which is proven to be possible it's just gotta work out how to do it for the whole internet. Obviously we can't just switch off the old and switch on the new, too hard, and all this is why optical quantum networks are still a considered option as we could easily just connect them straight to existing fibre optic cables (like those running under the ocean) and there's an added advantage of achieving quantum entanglement via a fibre optic cable, though I'm not sure how much of an advantage it would be on such a large scale. Either way, I'm making real plans to study some more basic maths and physics at university level next year so I can actually go to ANU in Canberra to do a Physics degree majoring in Quantum Physics (and probably honours as well...maybe a PhD...later). Anyway, I'll let you guys know exactly what's going on first hand (as much as I'm able) when I'm in ANU's quantum physics lab ^_^

This makes me want to write some scifi. Quantum internet sounds stupid handy.

Okay, what the hell is Erbium? I am completely geeking out because Erb is actually my last name. I have an element that starts with my last name??? Beyond epic.

watching from the year 3017 and lol'd at "we may not use this to watch this video" :D

2 qbits have the same amount of information as 2 bits. The two bits will still only take one 4 values. It's just we can express those 4 values as linear combination of 4 other values.

Well as far as I can see it you would only need to send the key via this method and the key isn't that big and you should only have to send it once if it's secure, but the only thing is if you have repeaters dones't that mean the repeater needs to read the information and resend it in that case isn't it kind of worthless.

I want that shirt!!

What makes me wonder is wireless Quantum Internet. It seems if entanglement is a thing and we can measure it we could affect one connected directly to the computer and it would send instantly across the world to something else and we could just measure there was a change and use that as your information distribution.

I've heard this argument in the history books: give it about fifty years and you'll see quantum computers in every door knob...at most hotel chains.

Super secret situations only when Q Internet becomes practical, but still super expensive. After some time it should be everywhere as it is increasing speed and power of computing! It is equally important as security. Imagine loading times everywhere as a past! Not worrying about games, apps performance is the future for developers. It'll enable to do much more and more quickly. Also, imagine a future computing, where there are no info on how much files weights in memory, or no memory info when you buy PC as it'll be no longer relevant, because it will be infinite!

This is a Quick Question: How do those color changing cups work?

Surely, based on the fact that if the Qubits are eavesdropped, they change breaking the encryption. Won't that make it a very easy Denial of Service Attack, but just constantly looking at the packets?

Just going to correct the end there, initially only for high level intelligence. Eventually all technology passes to nerds who make cool uses for it and it passes to the private sector only to be replaced by sub quantum computing and networking.

Well, somebody did say a couple of decades back that the market share for computers is around 6, so we'll never know if quantum computers will ever be a retail product for the masses anytime soon. Give it a couple of decades more I guess.

Isn't it true though that quantum computing is only suitable for a small selection of processes where the cubit advantage actually makes processing faster. Or like encryption, the reason isn't speed...

why do you need cable to send mesages via quantum computers? I thought it was possible to just entangle particles and "teleport" the message without giving anyone the chance to read it on the way

Would it be theoretically possible for a quantum internet to be as fast and content-heavy as the regular internet or would it be inherently limited?

early computers were the size of a building, now it fits in my pocket. this could happen to quantum too, making it an everyday item in 50 years. I don't think it will.

Not finding the article right away, but they already broken quantum communication making it obsolete. In this show they talk about routers. The first step was to put in your own router in between the origin and the receiver. Okay, what if you can't do that? Then they devised a clamp that reads the data, takes it off the line, then repeats the original data so quickly that the delay falls within error constraints. There currently are no thoughts on how to work around these attacks. Some scientists think there are no work arounds and we will have to really on normal actual cryptography. This being said, the Quantum Internet could really speed up how much information is transferred around.
