- “Quantum communication could become an integral part for any industry that values security in their communications” 🤯
Quantum is one of the Department for Science innovation and Technology’s five technologies of tomorrow and earlier this week we spoke to Karolina, a PhD student at the @UniversityOfYork Institute for Safe Autonomy researching quantum communications ⚛️👇
Research in quantum communications uses quantum mechanics to develop encrypted messaging and to safeguard data transfer. This technology could be the future of secure communications used across industries including finance, healthcare and government.
SUPERB explanation and easy to follow for "layman" ;)) Thank You !
Great explanation about the importance of quantum communications and privacy.🎉🎉🎉🎉
She looks like 16-17. Already PdD student? Bravo!!!
Very good universities accept students for their motivation and brains, not their age 💁♀
@Barock-mt8bc l know about it
Don't go over looks buddy. 😊
Looks can be deceiving.
The government wouldn’t let consumers have genuinely secure communications
That is an excellent point.
That's a great opportunity for another government to do the oppoaite, except if all the math studied individually prove it wrong
Hmmm
The government must be able to retrieve those in case of terrorism related issues.
Seems like you guys haven't got much terrorist activities in your countries.
@@surajmandal_567 we have a lot of mafia activity here instead, but that argument is more of an ad-hominem than anything.
Science doee not work like that even less regulations.
Scientifically, any one could learn how to refine uranium and make an atomic bomb, but the regulation is mostly on the uranium material, not on the knowlegdge spread.
Same with guns (go look at 3d printed ones)
Same with chemical weapons
The only form of protecting that knowledge is via patents, which is now on the commercial realm, or military patents (there is probably a better name, forgive me but im not aware of it rn), such as jets, but then, that was developed BY THE MILITARY
Assuming all governments work in a hiveming and would shut-down "safe" communication is a denial of you own reasoning
We already have that for a while, go look for Diffie-Hellman keys
Yet they let us have encrypted messaging which was safe for quite a while…
We capture a single molecules like water and use 4 forces laws to interpret the ambient influence on it the extrapolate to map reactions of all things physical
Who is this researcher?
this is how the Sophon on the 3-body problem suppose to work
That's just a stupid plot device that violates all laws of physics.
Quantum communication already works in humans. That is why a mother knows if something happened to her son in an instant, even if her child is on the other side of the world. Information is not limited by time or space. And people can develop this talent with the proper training. The US Army did it.
Wowwwwww..... This is interesting, I just clicked the video out of boredom but it was an interesting one
🔸🌊 Quantum entanglement 🔸🤺✨
No, can't be because entanglement cannot be used to transfer data (information).
Interesting... So QMC is presented as more of an encryption hash than a FTL communication method? My mind hurts....
There is no FTL. One can use quantum mechanics for encryption but it is not nearly as secure as she says. The devil is in the detail, unfortunately.
This doesn't explain anything. Bob has knowledge about a particular state of a photon being sent by Alice? And that is their little secret? We have PKI for that which is well established. So I don't understand what she is on about or how this could be a game changer in security.
the idea is that the "bitstring" changes is "cindy" listens to it. Whereas in a classical system one can read the bitstring and send out the same bitstring. Cindy can not konw what the actual bitstring is, therefor can only send out what cindy measures. This leads to a change in bitstring that bob receives and the data does not make sense. Then they can communicate to change encyption or smth.
Como es que Bob sabía como era antes, como para decir que verdaderamente cambio?
Yeah lots of pipes but we don't know if it works or not.😊
By observe one photon we can map entire city or country
Does she not know what encrypted apps like Signal are?
I don’t understand why distance would be a problem? Is it because of noise?
When photons travels through a medium it causes losses. Here the fiber optic cable which connects Alice and Bob causes losses.
@@venkatabhignan8410 So, this losses due to classical communication?
@@jbkrobin It's just classical absorption. A photon is a small amount of energy. Any impurities in the fiber will scatter or absorb that energy and then the signal that we are looking for is lost.
@grindupBaker Parasitic capacitance only limits data rates if you are driving that cable with the wrong impedance. You simply didn't know enough electronics to properly terminate and equalize long cables. Today we can send Gbit/s rates over the same cables.
@grindupBaker This was all understood since the 1880s, by the way. See "telegraph equation" and Maxwell.
awesome❤
💖❤️💖
So it's essentially a new version of PGP.
What's the catch? You gotta use really small words.
❤
True quantum computers will make security inconsequential and could end up like the nuclear option that governments should never use.
Xylophone music means it must be true.
Sound travels faster and stronger in water than air. Finding a way to communicate through dark matter? Is that what your saying. Advanced extraterrestrial worlds probably have achieved this, which makes me think that planet earth is much louder than the light\ radio waves its been sending out since the '30s.
Exploiting higher dimensions, faster than light travel and advancing relativity and universe structures maybe they have achieved
@@sokka90ml fairly sure we reside in higher dimensions but are too stupid to realise it.
She's a cutie

word salad.
Say more
Say you don't read without saying you don't read 😂
This sounds like utter rubbish.
Say more
It’s already being used by some governments and companies for short distance channels. China and the US are both working on implementing this with satellites
Then you should spend more time in the library 😂
