Quantum Teleportation Tutorial with OpenQASM on IBM Quantum Experience
HTML-код
- Опубликовано: 19 июл 2024
- Quantum teleportation is a fundamental concept in quantum computing. It introduces a lot of key quantum computing concepts. Here, I’ll cover what quantum teleportation is, the steps to teleport quantum information, and show you how to write this in OpenQASM - Quantum Assembly. I’ll also provide the code on my Github on who to do this with Q#, Microsoft’s Quantum Software Development Kit (SDK).

Quantum teleportation is a critical concept to take advantage of the powers of quantum information. It's the key behind quantum key distribution and long distance quantum communication, and also used in quantum computing. It allows you to "teleport" - or move the quantum state - to another qubit.
But why do we need to do something special to copy quantum information? For classical information, we simply read the bits, and copy them to another place. We can’t do that on a quantum system.
If we read out a quantum state, the superposition and entanglement is destroyed.
The no-cloning theorem says we cannot copy an unknown quantum state exactly
So, we have to do something a little different. Quantum teleportation is not copying information. It means we "move" the quantum state to another qubit. This requires destroying the state of the qubit we teleported, so we do not violate no-cloning.
Quantum teleportation has been successful over 4 miles in multiple locations over fiber optics, and 870 mi in space at the Quantum Experiments at Space Scale (QUESS) project.
Quantum teleportation requires 3 qubits, and two classical bits to teleport this unknown quantum state.

I love the video; I literally posted the the video on Facebook saying "we cover the same stuff, but I like more the way she presents it".
Thanks for this awesome video.. Love from INDIA 🇮🇳❤️🙏☺️
I been waiting for someone to share a video about this, Yessss!!!
I just fell into a quantum abyss. LOL. Thank you so much. This is interesting. Would You ever do a series That starts from the very basics of Quantum Computer Technology?
I would love more material like this!!! Thanks so much form making this type of material!
Really simplified explaining for starters. I`ve apreciated it a lot. I've been struggling with rigid theorical material for Phd's but I'm not Phd but I love QComputing and I'll not surrender until I understand it pratically and conceptualy even in my High School level knowledges of physics at a starting point. Thank you!
Thank you!! I know -- understanding that at that REALLY deep level takes time, and it feels like the rabbit hole is never ending. This is not how books usually do it, but hopefully it piques interest and fill in some gaps to make the rigid theory make more sense.
Thank you so much, I had difficulty to understand how to implement quantum teleportation.
Keep up the good work
This is the most concise and clear explanation and coding tutorials on Quantum Teleportation, I 've ever seen.💫
ThankYou. Next time BB84 🤩
Heya! Amazing video! Thank you... 😊
Quantum error correction is something I find researchers are focusing more on lately because that's what could lead us into the next stage kf fault tolerant quantum computers...
Explained very well with simple words.
Thank you Anastasia, hope you are doing good. ! I am loving Quantum Mechanics (till now
Thank you for an excellent concise explanation. Perhaps in an upcoming video you could explain why reversibility of the gates is important.
This was really informative, thank you for making this video.
Thank you Anastasia, love your videos!!👏🏼
Great explanation of the phenomenon 👍
What are the hardest problem you are actually working on right now? What problems people in your field think is the next needed breakthrough? Quantum related
Спасибо ☺️
@@Anastasia-Marchenkova I am still looking forward to your video on uncomputation, one of the topics hardest to understand for novice quantum programmers.
Excellent Explanation!
Glad you think so!
Can you do some more code videos.. this was very useful as always..❤️
Always waits for the video
Quantum Computing is cool
@@user-pw9zd8je8o tried saving in phone but not getting the contact in W.H.A.T.S.A.P.P
@@user-pw9zd8je8o ok it's working now but it's showing that you aren't on W.H.A.T.S.A.P.P
@@user-pw9zd8je8o ok I've got u
U r not from this channel
U have just named ur user name as 'Pinnedby•... '
Thank you as usual for the great video. A feedback if I may: imo the transitions are too slow, I would speed them up a bit

I took your video as the basis of my course work on the topic "quantum teleportation", I hope the teacher will appreciate and not find out that I copied your video)
I will update the comment as soon as he responds!
Hmm... you have an East Slavic first and last name)
Fantastic video, I'm actually in the middle of working on this exact protocol for a uni project lol! But I've been having some trouble, when you do the "disentangler-gate" at the end for Bob's qubit can you code this state to have it on placed on the bloch sphere using the "aer simulator" and:
out_vector = sim.run(qc).result().get_statevector()
plot_bloch_multivector(out_vector)
Qiskit's textbook had an example earlier without the disentangler that worked, however when including it in I kept getting a "QISKIT ERROR" saying that the disentangler sequence is not compatible. I haven't been able to find a clear answer anywhere explaining this.
Is there a way around this or should I just call it quits at this point? Thanks again
Thank you! I'm working on my thesis related to Quantum information and quantum computing and this is so good. I have one big question about IBM quantum computers. Can I execute the circuit using measurments to indicate the classic comunication on the real quantum computers? I mean, it seems to work but when I do tomography it looks bad, this could happend beacuse quantum computers has a ton of errors but, idk. What do you think?
In my highschool I got 2 type of math and 2 different teachers, alsoa very different material now I got confused with quantum teleportation 😂🙏
How I know I got this to work? And what application would I use this for? Great vid will be spending the rest of the afternoon to get this.
Can you tell me how to visualize these circuits ?
Самый красивый ютьюбер )) спасибо за контент
Ok so teleportation is a way to send quantum information over a very long distance. First I need to physically transport the qubit to the recipient, then due to entanglement, the change in state on both qubits is instantaneous, and when we want to measure, the states collapse and the message is received and interpreted. Is that correct?
Hey Anastasia, thank you for this video. I have one small doubt regarding measurement in different basis. The unitary that we should apply before making a Z measurement should be transforming the computational basis to the desired basis of measurement, right? I have often seen people say the other way, they say it takes from desired basis to computational basis and they don't say that we should invert the unitary. So, I am a bit confused.
this is entertaining.
You are doing some higher level coding I don't understand! But this seem interesting I want to do this. I just wanted to ask one question. Is your MacBook your quantum computer?
Nice video. Any good references or books to expand on the subject?
@@Anastasia-Marchenkova Thank you.
Good luck with the channel.
I actually took up a project in Quantum teleportation for my master's project and i have not much idea about it,i think it is a good project but I'm so unsure about it now,i don't think I'm good enough to study it
I am an old retired computer architect and software engineer so I have a /strong/ understanding of "classic" computers internal working. I'm just starting to look at Quantum out of curiosity, and I found your videos are an excellent starting point. I have a question for you, probably naive, but I would really want to know: Is quantum entanglement over very distant places even a possibility?. If that's the case, I guess it would open the opportunity to essentially have instant long distance communication (even between people on different planets, such as Mars to Earth communications, now requiring minutes to hours due to speed of light). Thanks in advance
Entanglement is independent of distance, to the point where it appears to play a strong role in forming what we perceive as "distance" itself -- spacetime. Many smart people have considered FTL communication through entanglement, but long story short, the act of reading the message creates a causal link between the sender and receiver, and (full, information-carrying) causality always travels at c. A little searching should bring up several good resources on the topic.
Can you do an interview with Lex Fridman? I just think it would help a lot of women out there on getting to know you and what it takes to be a quantum physicist. And I think the conversation would be enlightening on technology with the help of both of your personalities. I just feel it doesn’t hurt to ask but GREATLY helps if actions DO take place.
I love you
@@user-pw9zd8je8o how
I actually believe in a teleporative force that stems from the universe not being predetermistic. In other words, the universe is randomly generated at every instance of time. And if we were to time travel back in time, events will play out completely differently. I thought you were going to talk about that. Also, in my opinion, particles should be able to spontaneously collide but they can't because of a teleportative force. That's just my opinion.
LINDA!
Wow😲
@@user-pw9zd8je8o 😊
just without watching the whole video is nt the term "teleportation" an abuse of language and quantum entanglement more close to what one could call "ubiquity?
After quantum mechanics comes light computing
grwat video but how do i apply this to make $ in crypto ?
I think I've seen you in some movie
you stunning 🌷💖💖
Quantum mechanics gibt es in normalen rechnern schon dort setzt man dies ein
Going AI Day?
weird movie without subtitle.
@@user-pw9zd8je8o Dont get me wrong is my fault i dont understand all but you`re doing a great job explaining things for someone like who is doing front-end dev.
There are auto subtitles and translations in multiple languages of this video.
Turkish language?
I'll give you 3 dollars if you break 3 bit encryption on quantum computer.
