Who Has The Best Quantum Computer?

This is a summary of all the main companies building quantum computers today, and what their most powerful machines are. You can get the digital image here: https://www.flickr.com/photos/95869671@N08/51849762629/in/dateposted-public/ But we can’t simply look at qubits counts because so many other factors go into the quality of a quantum computer, so here I look at the quantum volume metric which is a much better way of comparing machines. And we look at what steps these companies need to take to achieve large scale useful general purpose quantum computers, and the timelines the companies have set out to achieve these.

This is the Map of Black Holes which isn’t a map of where all the black holes are in space, it’s a concept map of the subject of black holes: laying out our current knowledge of them. Their structure including Schwarzschild radius or event horizon, the singularity, photon sphere, innermost stable orbit, accretion disk, Hawking radiation and the difference between rotating and non-rotating black holes. I also look at the evidence for their existence, the many ways we have detected them though x-ray astronomy, gravitational wave astronomy and radio astronomy. Then the many outstanding mysteries still to be solved including wormholes, the holographic theory and information paradox. They are very fascinating objects indeed.

The Map of Superconductivity

The Map of Superconductivity poster is available here: https://store.dftba.com/collections/domain-of-science/products/map-of-superconductivity-poster
Superconductivity is a fascinating property exhibited by many materials when they are cooled down to cryogenic temperatures to below a certain transition temperature. Below this temperature they lose all of their electrical resistance and they are able to conduct electricity with zero loss of energy. They also exhibit interesting magnetic effects including the total expulsion of magnetic fields from their interior due to superconducting eddy currents.
In this video I look at the different kinds of superconductors like type-I and type-II superconductors, and high temperature superconductivity, the theory behind them: Ginzberg-Lanadu theory and BCS theory,, and the applications of them in the real world which include superconducting magnets for MRI machines and particle accelerators, quantum devices like josephson junctions and S.Q.U.I.Ds for uses like quantum computing.

In the Marvel movie Ant-Man, he wears a suit that makes him small. But if his limiter stops working he gets too small and will enter the quantum realm where bad things happen (apparently). I hadn’t seen this film but lots of people in my comments were saying that they discovered my quantum physics videos because of Ant-Man, so I wanted to take a look for myself and see what the quality of the science is.

The science in movies is often a bit wrong, especially when it comes to physics and even more especially when it comes to quantum mechanics. But I’m okay with wonky science if it is needed for the plot. They are stories after all, not university lectures. So my challenge for myself was not just to gauge the correctness of the science, but also see if I could come up with better scenarios that use correct science, but also still maintain the needs of the plot and story.

Fundamentally everything is made of particles and these particles are are described by a quantum wavefunction. But what actually is it, and is it even real? Support this channel: https://www.patreon.com/domainofscience and https://store.dftba.com/collections/domain-of-science

Here I explain what they are and show a visualization of what they look like, and show how they are similar to many other waves we are familiar with.
Overall the wavefunction is a mathematical tool which keeps track of all of the properties of a quantum particle, and explains our observations of the probabilistic nature of where particles appear when we do experiments on them. From the wavefunction we can calculate all of the observables like position, momentum, energy or spin, by applying mathematical operators on it. So in quantum physics, the wavefunction encodes all of the information about the quantum system, and valid wavefunctions are solutions to the Schrodinger equation which I covered in my last video which you can watch here https://youtu.be/AR23uxZruhE

The Schrödinger Equation is the key equation in quantum physics that [...]

The Schrödinger Equation is the key equation in quantum physics that explains how particles in quantum physics behave. You wanna know where your electron is going to go? That’s the Schrödinger equation you’ll need.

So why does it look so complicated? Well it’s because in quantum physics, when you are describing what a thing like an electron will do, it doesn’t follow the rules of particles it follows the rules of waves, and that’s what these psi’s are, they are wave functions.

Okay so an electron is a wave, and a wave can evolve in space and in time, but it can’t evolve in any old way, there are constraints about how it can evolve, and those constraints? That’s what the Schrödinger equation is telling us.

It says that over time the total energy has to stay the same. And this total energy is made of the kinetic energy, and potential energy. An example of a potential energy for an electron is just being in an atom.

So if you want to see what a quantum object will do in the future, you need to find the wave function that will satisfy all these bits of the Schrödinger equation.

Arguably the most likely way we will first discover alien life on another planet will be using the power of atomic spectroscopy. You can grab the Map of Quantum Physics here https://store.dftba.com/collections/domain-of-science/products/map-of-quantum-physics-poster

Aliens will most likely leave a tell tale trace of their life in the atmosphere’s of their planet. But how do we know what chemicals the atmosphere of a distant planet contains? The answer is atomic spectroscopy. If we see a planet passing in front of it’s star, some of that starlight is absorbed in a very specific pattern called an atomic absorption spectrum. Each element has a specific pattern like a barcode, so through careful analysis of the light it can tell us which gasses are in the atmosphere and their proportions. We already use this technique for other space objects like stars and nebulae, measuring properties like temperature, density, ionization and relative velocity. This is a gift that nature and quantum physics has given us and the majority of what we know about the universe is based on this technique.

The Easiest Way To Make Delicious Bread

This is straight up a baking video, the best bread recipe I have come across for maximum flavour with minimum effort. I thought it could be helpful in the coming weeks and months at home. The full recipe is below!

I didn't want to do a video about the virus because I think it has been really well covered elsewhere. I hope you and your family are all hunkered down and doing well. Wishing you all the best, and I'll be back to my normal science videos next week.

----- Ingredients -----
- 3 cups (400g) of unbleached all purpose flour
(or 2 cups all purpose flour and 1 cup wholewheat flour)
- 1/4 teaspoon instant yeast
- 1 1/2 teaspoons of table salt
- 1 cup (240 ml) water
- 1 tablespoon of white vinegar
- 1/2 cup (120ml) mild lager

----- Instructions -----
- Mix dry ingredients, then add everything else and fold together. Let sit for 8 to 18 hours at room temp in sealed bowl.
- Knead dough 15 times, pull edges into middle to form a ball and flip seam side down.
- Line same bowl with oiled parchment paper, put dough on it and lid on for 2 hours.
- About 30 mins before baking, heat up a Dutch oven in oven to 500F (260C). Lightly flour top of bread and with sharp knife make two slits in the top.
- Carefully transfer dough to pot and reduce oven to 425F (220C) and bake covered for 30mins, then remove lid and bake for a few more minutes (5-10mins) until brown.
