Quantum Computing for the Very Curious – A long-form article by the author of the preceding videos.

Your great videos inspired me to try to explain come quantum phenomena to some math phobic colleagues in this series: http://mycodehere.blogspot.com/2011/11/quantum-computing-5-quantum.html (no ads) – but they boiled it down even further by making me remove most of the matrices, vectors and greek letters! Also can you suggest some GUI based software in which we can simulate the simple quantum gates with single or multiple qbits so we can raise the complexity of the circuits , vary the inputs and observe the output of the gates . Quantum Computing for the Determined – A series of 22 short explanatory videos, starting with The Qubit. 15
I watched the first video and I can’t wait to watch the rest. Another vote for the complete series. Sat down to watch the first video this morning, and now it’s gone 8 in the evening and I’ve finished them. Note that because this really does get into the nuts and bolts of how things work, it also builds cumulatively. Quantum computers are great for solving optim isation problems from figuring out the best way to schedule flights at an airport to determining the best delivery routes for the FedEx truck. It’s a bit harder to read than an article in Wired or Scientific American, but it’s worth the effort, for the paper gives a lot of insight into some of the fundamental reasons for thinking about quantum computing in the first place. In particular, you don’t need a background in quantum mechanics to follow the videos. JavaScript is disabled for your browser. Again, time prevented me from doing this: there are no exercises. It’s pretty interesting stuff. A qubit might be one of those unmeasured electrons. By Nielsen, M. (Michael) (2010) Presentation Slides. Really looking forward to the next set when you get around to it! (The fact you got it right strongly suggests you’re really understanding this well!). Sir, your videos are excellent. Hello Sir, It was a pleasure watching this videos , hope you complete them . Google announced it has a quantum computer that is 100 million times faster than any classical computer …

that did Shor’s algorithm and then the 7 qbit one. 6
I just completed watching the video series (15 minutes is perfect for watching while on an exercise machine). Conversely, since I never had any advanced physics classes, I’m baffled by advanced scientific books presuming readers are already fluent with all the basic notation and elementary concepts of QM. One more vote for more. A few rare resources, such as your videos, are aimed at exactly the right level: using the necessary math to construct the right mental models to create understanding. Thanks for putting up these videos! I come from the wish to go deeper into quantum cryptography. Quantum computing for the determined. by Michael Nielsen on June 10, 2011. 7
Partial measurements -
Quantum computing for the determined. You can’t just skip straight to the quantum teleportation video and hope to understand it, you’ll need to work through the earlier videos, unless you already understand their content. 21
I watched the 22 videos, and im curious how any algortihm might take advantage of the possiblities offered by the information in the state space. Unfortunately, work responsibilities that couldn’t be put aside meant I had to put the remaining videos on hold. Partial measurements in an arbitrary basis -
Rather silly to have missed that comment.
Where will the key ideas shaping the future of scientific publishing come from? And while we still have little understanding of that relationship, many in the QC field view it as a notable use case. The controlled-NOT gate -
Lec 22 just stops! 16
Or is it just a lull before its going to come back in a big way? A few years ago, I made it a goal to actually understand QM before I die. I definitely would like to see the last 8 videos made, if you have the time! 10
What's so special about entangled states anyway? It turns out that my problem was two fold. I’ve posted to YouTube a series of 22 short videos giving an introduction to quantum computing. It really is appreciated a lot. It will be of immense help if you can manage some time and finish the course. Here’s the first video: Below I list the remaining 21 videos, which cover subjects including the basic model of quantum computing, entanglement, superdense coding, and quantum teleportation.
Its been great to study these lectures along with following your book. -
I’m a cryptography student. Its greatly appriciated! I would love to see the course completed! (Looking forward to it!). Inspired way to approach the subject.
First I hadn’t quite thought the consequences of the cNOT gate through, which has sunk in after reviewing the vids. Loved the lectures, any chance you will do more? I do hope that you complete this set, and also do something on algorithms? It’s purpose is to keep an eye on the evolving quantum computing industry and I just had an entry about how it’s prospects are undersold in the media: http://wavewatching.wordpress.com/2011/09/28/45/, Yet another vote to complete the video series, or at least “The postulates of quantum mechanics IV”. Go finish the videos when you have time Michael. The race toward the first practical quantum computer is in full stride. You bring up the Khan Academy in the course and blog – have you considered working with him to make this one of his courses? +1 from me to complete them when you get some time. I’ve seldom seen QM-related material explained so simply and clearly. As regards superdense coding, I simply made an error. Superbly clear presentation. If you want a high-level overview of quantum computing, why it’s interesting, and what quantum computers may be capable of, there are many available online, a Google search away. Could you verify if there is a mistake in the video of whether I should slap myself and start over again. Please do!! General single-qubit gates -
I did a BSc in mathematical physics in Bert Green and Angus Hurst’s famous old dept in Adelaide many years ago (probably before your time) and have never entirely lost my interest, so I’ve seen the Hilbert space formulation before and solving the hydrogen atom, quantum scattering etc etc.
