Crafting Qubits: Harnessing Quantum Mechanics for Computation

How do we actually create and manipulate qubits, essential for realizing quantum computation? Chief Scientist of Hardware Technology Development at Quantinuum, Patty Lee, joins Brian Greene to discuss various quantum strategies, their achievements to date and pathways forward.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

I appreciate the efforts Dr.Greene and the WSF have undertaken time and again to bring these enlightening and cutting-edge conversations to the curious masses.

[crazieeez]

Love this a lot. Brian is good at asking the right questions. She is so smart.

[RamaChandran-pm]

I greatly enjoy the WSF content and Prof. Green"s hosting of this very educational content for the scientifically curious-minded. We are blessed to live in an era where we can choose to learn from such luminaries for free from our living rooms, which would have been unthinkable just 50 years ago

Finally, a understandable presentation on Quantum Computers. THANK YOU SO SO MUCH.

[jakewelch]

She is an excellent speaker and communicator. 👏

[robinbrowne]

Every time I hear about quantum computing I learn a little bit more about physical qbits, entanglement, superposition, decoherance, logical qbits, measurement, etc. Thanks for the video 🙂👍

[Vince-mlgw]

“How does one talk to the quantum computer?” Priceless. 👏🤩 Awesome conversation. Thank you so much!

[lightlegion_]

Keep creating! You’re producing excellent work!

[williamjmccartan]

I hope the host doesn't mind, I just wanted to let everyone know that if they are interested in the tech D-Wave has its own utb channel, this was podcast was a good source for material, thank you for sharing this presentation in open media as this is such an important medium, thank you both Patty and Brian, peace

[shahramzahedi]

it was great, thank you so much, it makes clear many steps on QC for me

[joonsanglee]

Thank you so much for this educational video. My lab just started quantum mechanics research using a quantum computer (IBM). And I am getting very interested in using some other qubit platforms like Xanadu now:)

[onionknight]

Dang Dr green you that was so cool another great interview

[williamjmccartan]

I've added this episode to my library, just a place I've been building for several years now, Seeking a little knowledge and wisdom + a little fun on utb as well, peace

[flounderflounder]

The interviewer asked such good questions

[victorbellew]

I like the old shows with the panels better but I imagine this format is easier to organize so we get more of them.

[rogerwilcoshirley]

would be interesting to compare content of this discussion with that of a graduate course in quantum computing. one thing for sure, its incomparably easier to chat about physics than to actually do it. nonetheless a nicely done Q&A.

[rachel_rexxx]

Ah, WSF, a welcome respite from politics.

[IAMHYQV]

Yes, once entangled the bits can share the same info even when they are in different places universally in other ways two points or more become the same

[silberlinie]

So very satisfactory answers. You don't get the
feeling that you're getting concrete information
about the various questions.

Why not ask for a single, concrete task?

This is defined very precisely, as is usual with
conventional computer programs. Then you
would be able to make a comparison about
whether and what and how a task is solved.

But here I keep hearing: yes, it depends.

I remember that 20 years ago it was said that
with 7 functioning Qubits the most extensive
calculations in the universe could be solved
in a few seconds.

What has come of that?

Much of this conversation seemed to me to be
caught in the same hazy fog as it
was 20 years ago.

Neural Nurishment as always. I love the WSF.
