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.
