It does matter how the Qubits are entangled at the beginning as that is precisely what will effect the eventual correlations. See, this is what everyone ignores and partially why the Bell Inequality is not a valid statement.

The Bell inequality is complete rubbish as it neither supports a quantum view nor shows any proof of entanglement. Einstein was likely correct, and the problem needs to be revisited in the search for local hidden variables theories... Clearly, the Nobel committee made a mistake.

Is Sheldon watching this video?

eto boi kemne pore bhai.......................................

cannot import name 'pauli' from 'qiskit.quantum_info' !!!!!!!!!

Amiri

Imagine it came from a similar phenomenon as the double slit experiment and why sun rays have weird angles under clouds 😊

Thanks Guys...

Very nice

Do we have to execute 'conda install pip', ' pip install qiskit', 'pip install jupyter' everytime we start a machine (windows)?

It is another confirmation of the fact that we are in a digital simulation - see Thomas Campbell work

Was the matrix described @24:02 correct on the screen? Didn't seem to tie up with what was being said.

Thanks for the awesome introduction, Ma'am. I remain highly expectant for the next.

<qiskit.circuit.instructionset.InstructionSet at 0x26aeddee080> how I can resolve this ? please help.

Thank you

Note: cu1 is deprecated use cp instead!!!

Are the slides available for download? They've been very handy for the "Understanding Quantum Information & Computation" presentations. Thanks and looking forward to these presentations.

It was all great as always, but I have only question about this formula just want to know from where it derives |ϕ_b⟩ = (1_A ⊗ ⟨b|) |ψ⟩

If only I can understand her chicken scratch. I love whiteboarding and handwritten teaching BUT...if you don't have good penmanship then have someone write for you.

If I succeed my exams it will definitely be thanks to you. You made me understand quickly many concepts I struggeled to figure out before. Thank you for all your work in making this complex subject a little bit more accessible !

Great video and as Jerry says, an exciting time at IBM. Glad to see Big Blue is still at the cutting edge of not only research but proper engineering too.

Gordon Moore's observation was only about the number of transistors. He didn't mention anything about their size. Good introduction. Looking forward to the rest of the series.

Your explanations are always easy to follow even when they lead into the abyss of reality. Please allow 2 questions (and perhaps somebody else in the comments can make useful remarks to it: a) would the full range of solutions be -2.8 <= -2 <= (A,B) <= 2 >0 2.8 or do negative values need to be included; b) that you can save locality and realism as one has a theory how values x and y are related, I don´t need to know what the 2nd party/Bob measures, I introduce one value and the theory: value x and y is a function of x so y = f(x) which allows me to deduct the value Y w/o having it ever measured (sth analog to Maxwell´s demon in TD?)

Your recommended for . Toilet papers

is this the last in the series ?

Try to talk without ending the sentences witaut annoying knarring

Why is a thought experiment not enough? It's well thought out and follows the simple rules of the universe. 😊

fantastic explanation!

35:41 FOR QFT

I am Isai, I follow this course... really clear and neat teaching of a such complex topic...

Could I say that quantum mechanics is like searching for the reflection (realisation) of an imaginary world? Is part of that imaginary world a frequency value, amplitude, phase, under minute thermal fluctuation controlling the value states of the particle?

If you do not have in your team but at least one American J. you never get a Nobel prize. Nikola Tesla Describing Quantum Entanglement In 1891. “Nature has stored up in the universe infinite energy. The eternal recipient and transmitter of this infinite energy is the ether. The recognition of the existence of ether, and of the functions it performs, is one of the most important results of modern scientific research. The mere abandoning of the idea of action at a distance, the assumption of a medium pervading all space and connecting all gross matter, has freed the minds of thinkers of an ever present doubt, and, by opening a new horizon-new and unforeseen possibilities-has given fresh interest to phenomena with which we are familiar of old. It has been a great step towards the understanding of the forces of nature and their multifold manifestations to our senses. It has been for the enlightened student of physics what the understanding of the mechanism of the firearm or of the steam engine is for the barbarian.” -Nikola Tesla “Experiments With Alternate Currents Of Very High Frequency And Their Application To Methods Of Artificial Illumination.” Lecture delivered before the American Institute of Electrical Engineers, Columbia College, N.Y., May 20, 1891.

Will there be other videos soon?

it would be nice if examples existed for once

9:37 why would a conjugate exist 1)these are two different variables with two different notations

There is a term used to describe that speech affectation which plagues even geniuses like this young lady. It is 'Vocal Fry' and is one of many bad habits Americans have invented in recent years.

Nice 👍

Thanks for amazing video. I have 1 doubt: In our Quantum Circuit, we have not included measurement step for control qubit, target qubit and storing result to cr3 register. But at the end, during post processing, we had used cr3 register. How compiler is sure the results are stored in cr3? When I included these steps, I also had to put i in place of i+1, i.e. in post processing step I put data=result[i].data in place of result[i+1].data. Then program worked. Can you explain it?

Qiskit bro is back!

I am looking for BB84 simulation on Qiskit.

Awesome Derek, a fantastic Qiskit Intro! Well done and keep going compiling the tutorials in the same style... really appreciated the condensed and swift walkthrough the code and step by step instructions... 👍

I am a first-year university student in Japan, and I recently became interested in quantum computing after watching videos of IBM's researchers. I hope to specialize in quantum computing and work at IBM in the future. Since my university only offers classes in Japanese, these videos are truly invaluable to me. I plan to study abroad extensively to improve my English skills and fulfill my dream. Thank you very much, Professor John Watrous. I look forward to the next video!

Great talk! Thank you!

I thought statistical independence was the third assumption?

This would be a much richer post if you explained the terms in ⟨S1​⟩∣=∣⟨AB⟩−⟨Ab⟩+⟨aB⟩+⟨ab⟩∣≤2, why three are additive and one subtracted; could any single term be subtracted, if not, why THAT one? Why not some other arrangement? What's the meaning of the terms and the equation? 2.8 is obviously 2* sqrt(2), but you didn't think that was noteworthy?

I wish she'd just use her natural voice ....

Actually, there is no 'realism' assumption in Bell’s theorem. This is a very incorrect presentation of the theorem. The only mathematical assumptions, in addition to 'local causality,' are ‘dichotomic outcomes’ and ‘statistical independence’. This is why it is possible to violate Bell’s inequalities by exploiting detection and memory loopholes.

So did anyone manage to get a job?

keenly looking forward to the next episode (is there going to be one? or, do we go back to the current lengthy ones!)

You´re just selling mainsream QM here!
