Building a quantum computer with superconducting qubits (QuantumCasts)

[anabakhtar]

This is definitely the MOST INFORMATIVE video on Quantum Computing basics. Thanks a lot Mr kudos to Sergio for such an amazing push

[shashvatshukla]

Man this is one of the best explanations of quantum computing. I'm so jealous of you that you thought of all this.

[Hifi]

Wow. Incredibly well explained with subtitles in multiple languages. Please keep up this great work!!!

[linkcell]

This is my favorite vídeo series right now. Please more episodes :)

This is one of the most illuminating and inspiraitonal videos on quantum computing. Mr. Sank seems so passionate about the subject and excited to share the knowledge with people who would like to know the fundamentals of quantum computing. Thank you~

BU zamana kadar dinlediğim en açıklayıcı bir video olmuş. Teşekkürler

I’m an electronics technician not an engineer, so this is definitely the most easy to understand video I’ve seen on quantum computers. I’m assuming one day, Q computer technicians will be needed so I’m trying to get a basic grasp of it.
My question is - how many computations does the computer perform before an accurate answer can be obtained using probability?

Not easy concepts to explain but good video

[negarahani]

Great video! Would be interesting to learn more about the materials science side, fabrication methods, and the challenges you face.

Thanks,
Great job

I have two questions:

do you only keep the two lowest energy states for the qubits to keep superposition of two states ?
If yes how do you prevent an aggregate of atoms from going to higher energy states ? If no this means that one bit can be represented by the vector [0, …, 1, …, 0] (with one on the active energy state the system collapsed to) once measured, could you point some material to know how to build circuits like addition multiplication with such vectors ?

Best explainnation for quantum vs classical bits

This video was excellent. I can say that I have a very basic understanding of quantum computers. How can we observe superposition without changing it? Due to the cooling?

Shouldn't the red arrow from (000, 101) leads to (101, 000) not (100, 000), just as blue arrow (000, 100) leads to (100, 000)?

Sorry for my lack of location notation, but i hope you understand my question.

[saskiavanhoutert]

How noise can be reduced by Quatumcomputing, perhaps through using ledsignals by transmition of qubits. Just a thought
Thanks for explanation and kind regards.

Amazing video! thank you! well explained. I think its great to learn more about how errors get produced! We should have a think tank for the subject. Qubit fab is the future. I can't wait to hear more from the team regarding its progress. Also what classes / degrees are required to get into this type of work?

I'm still confused how logical operations are performed and the results observed. A good amount of time of this video was spent focusing on explaining the protection the qubit circuitry from any interference, even so much as a photon, but then it was said that logic operations are sent to the qubits for processing, and no explanation was given.

(1) How are the logic operations sent to the qubits for processing without changing the qubits into an unknown state?
(2) And how are the results observed without altering the answer? Observation involves interaction with the qubit, even if it is so much as a photon or a very sensitive electromagnetic field sensor that responds by sending out a signal (which itself generates a new electromagnetic field), and if the qubits are supposed to be protected from such things, how are answers observed?

Thanks for the video Daniel,
If I got it well, you are proposing a new chip (8 times colder than space) simulating the operations of Cryostat. The superposition is ensured by the Superconductivity at steady rate, but we could have some errors.
My questions: Does this chip also manipulate true electrons inside for the superposition states (as the Cryostat), or States are hardcoded in the simulation? Is it possible to use this chip to create small quantum computers (like PCs) and make them available for the public?
Correct me if I made a mistake, please.

When tou have elletrically full guide then you have a porzadek in electrons. The lingual of the guide will also be less to "stack"/ [ordering].

9:06 Why can the method of a grid of qubit solve the uncertainty of data?

[vitalliquid]

I need to learn more about this! How can I come up to speed on the subject?
