Inside a Quantum Computer! with Andrea Morello (Part 1 of 2)

An in-depth look at the engineering inside a quantum computer, and also demonstrating the operational results live and how they are measured.
With Professor Andrea Morello who is the Scientia Professor of quantum engineering in the School of Electrical Engineering and Telecommunications at the University of New South Wales, and a Program Manager at the ARC Centre of Excellence for Quantum Computation and Communication Technology.
Part 1 of 2

00:00 - 🔬 Discussing job opportunities and showcases a quantum computer experiment at the Fundamental Quantum Technologies Laboratory in Australia.
7:14 - ❄️ A refrigerator that can cool down to 4° Kelvin using helium gas.
13:23 - 🔬 The design and purpose of a filter box used in low temperature experiments to filter out high frequency signals.
20:11 - 🔬 Research and new science are being done with prototype chips that can stay in a fridge for up to four years.
27:14 - 💡 The video explains how a transistor works and how the movement of electrons can cause a shift in the pattern.
33:36 - Silicon is a practical choice for quantum computing due to its semiconductor properties and isotopic purity.
40:39 - 💡 Magnet quench is when a superconducting wire goes from being a superconductor to a normal resistor, causing a significant amount of power dissipation.
47:41 - 🔬 How a refrigerator is used to cool down the electron electrochemical potential in order to populate the spin down level for magnetic resonance.
54:30 - 🧪 Designing a cancer cure on a classical computer is computationally complex due to the quantum nature of the problem.
1:01:14 - 🔬 A startup has developed a commercial machine for Quantum control that allows users to manipulate and operate a large multi-dimensional Quantum system.
1:07:29 - 🔬 Advantages of using silicon MOSFET over other materials for spin-based operations.
1:14:09 - 🧲 The magnetic field created by the solenoid is more stable than the magnetic field of the superconducting magnet, with a very slow decay rate.
1:20:40 - 🔬 Improvements in coherence time and scalability of superconducting qubits in quantum computers.

This is one of the absolute best videos on quantum tech that I have ever seen. Morello explains it so thoroughly and comprehensibly that it is a pure pleasure to listen to, and Dave supplements with really good questions that tie it all together. I'm just a "simple" electronics engineer, with an MsC from a long time ago. Today I work with system architecture in cellular radio systems... but, before I started my engineering career, I was admitted to the Niels Bohr Institute in Copenhagen. Although I chose to jump from Niels Bohr to become an engineer, I have maintained an interest in quantum mechanics, and this video has really boosted my positive spin in that direction.
Brilliant video - Thnak's to Andrea and David.

It's absolutely a joy to listen to Prof. Morello explain how things work. The education system needs more like him!

[chrisbastoscb]

This is top notch content, I would love to see lectures from professor Morello, what an amazing work.

[Sailingon]

Wow never expected to have even a small amount of understanding of quantum computing but Prof Morello explains thing so well i actually feel like i understand, wish i had a teacher like him id have lived at school.

[colin]

I can't believe how lucky we are to have access to such knowledge so fluidly. Thank you so much.

[aenima]

Andrea is so good at explaining things and keeping it soo interesting. Can't wait for part two.

[bytex]

Finally a video that describes actually how it is interfaced and interacted with in a understandable way :) I have to agree, Professor Morello is a joy to listen to.

[entropyachieved]

Great vid. Prof Morello knows his stuff, I've seen him in a few vids over the years and he is great

[nullifier_]

I remember watching a video of his almost a decade ago with veritassium talking about computers. It's great seeing this video recomended to me and that this guy is still rocking

[AngelinaCruz]

44:23 Have you ever experienced intercepting signals to the 40 G micro-waves?

[chrizzLanc]

You can clearly see the bright in his eyes... Such a great teacher/professional.

[leaovulcao]

Awesome, Professor Morello! You are a G! In a Superposition! You are Blessed by Nature!

[BooleanDisorder]

I saw Professor Morello first time in Veritasium a decade or so ago. Glad he's still on it!

[erikalcalasalero]

This happens whe someone -wants- and likes to teach ! Thank you for such an amazing video !!

[ikocheratcr]

Love it. The professor explain very nice, easy to follow, but still a load of info there.

[robingalipeau]

hell yeah!!! finally a follow up to the Can't be more happy!

[paulbyerlee]

Your last conversation was golden. This is the same. Thankyou for sharing your time and expertise.

Great video! I'm / was also a cryogenic physicist, @ < 4.2K level. Thermometry at those temperatures is also my specialist area.
Really beautiful cryostat and experimental setup (Cu and Au). Once, I created superfluid He(4) by pumping it down to ~1.4K, if I remember correctly... inside a double glass dewar with window slits..so I could see the vanishing of any boiling bubbles. It was used to check the calibration of a Si diode thermometer.

NOTE: Just lame AI generated timestamps at present. I need time to go through and do them manually, there is just so much in this video!

[Petertronic]

Fascinating from start to finish, this was amazing. Looking forward to the next part.
