Is entanglement the key to quantum computing?

In this video I describe my PhD research in quantum computing. Is entanglement really crucial to a quantum computer? The standard wisdom says yes but I wasn't so sure.

Here are a few citations:

It is really inspiring to hear someone being so open about a mistake they made, since it's so hard to do that. Thank you for another great video!

[joelbeckles]

Wow, those 17 minutes and 42 seconds felt like a real roller-coaster! Can't imagine what it was like for a few years. I can definitely relate to wanting to stick on something for so long when you feel like there's something there😂. Congratulations! Really happy for you. (Also, it's refreshing to get a clear explanation of what a PhD student does without them over-simplifying)

[margaretinnes]

As an individual with very limited mathematical knowledge and small scientific training, I find your videos fascinating and enlightening. Thanks for putting them out

[rockerrock]

I am pleased you were able to admit to a mistake and fix it, and I didn't know it was so common to have multiple Ph. D projects, that is crucial knowledge if I decide to continue for my doctorate after this December, so thanks for the insight.

That was a beautiful story. My daughter is in a PhD program in neurophysiology. I think she should hear this, because she has experienced many of the same highs and lows. Thank you for sharing.

[joaobaptista]

Awesome story! The fact that you told us about your reseach from a personal perspective with so many highs and lows made it so much enjoyable. Also, as I am myself a PhD student that had to switch project due to a dead end after working really hard on it, I could relate so much to your strugle and got very pleased to see that you managed to work it out. Truly inspiring. Congratulations!

Wow this is such an awesome story!! Super engaging and thought-provoking 😁

I’ve been subscribed to your channel for years and watched every video as soon as I could. Although the format and content have changed a bit, each one is a gem unto itself. Thank you so much for continuing to make videos!

[shashvatshukla]

I'm beginning my PhD in Quantum Computing this Fall. Thank you for sharing your honest story. I know the PhD will be tough but it is so great to be reassured that people do make it through despite things not going according to plan, and so satisfying that these missteps are actually all part of the larger process of understanding things. This video was such an emotional rollercoaster!

[thedoublehelix]

My heart sunk when you mentioned the flaw :(. I couldn't imagine working on something for so long only to have it be worthless. Good thing you managed to fix it

[JulianFoley]

What a delightfully compelling tale! I barely hung on thru the grisly detail, but was entranced by your perfect evocation of the emotional roller coaster of confronting a Ph.D.

[ProjectPhysX]

Admitting such a mistake is the right thing to do, thank you for being so honest! I've had a few papers that stole months of my time for nothing because I couldn't replicate their algorithm and then finally found out that their equations were all wrong.

[adarshkishore]

Your experience shows that work never goes to waste. Even if you don't achieve what you started with, you often learn a lot of things. It's the journey, not the end, that matters. Thanks for sharing this with us

[RyanJardina]

The way you explain the concepts are far better than anyone else's videos I've seen.

[Eigenbros]

Excellent video, Mithuna. It's inspiring to see how far you've come as a forerunner in quantum theory. We're all are lucky to have a such a solid explainer on these difficult problems. Can't wait to see what else you come up with in the future 🔥🔥🔥

[nikhil]

For years you keep enlightening us with really complex concepts in the most natural and articulate way. So happy for you! Kudos

[justpaulo]

Thanks for this!
As a layman I had no idea of the importance of entanglement to quantum computing, and all the debate you mentioned.
All videos I've seen so far about QC just talk about superposition.


PS: congrats on your PHD and I tip my hat to your ethics (and resilience, and courage).

[satishchandra]

The picture at 2:02 sums up everything. What a great explanation.

[dibenp]

It has been a joy to watch your journey in this topic over the past seven years. I have learned a lot by watching your videos, and I have really enjoyed your style and humor. Looking forward to calling you Dr LG. 😄

Great job Mithuna! If anyone is interested in seeing an interview with Mithuna, on this very topic, there's a somewhat technical podcast with Mithuna on our channel, as she generously spoke with me on Quantum Computing and Quantum Foundations. Thank you Mithuna. - Curt
