    So well explained. Love the clarity of thought. But superposition and its usage still needs further simplification. Thank you Marissa

    This blew my mind. The implications and functions a qbit could produce. Wow. We could run really accurate simulations or preform a million calculation a second with thousands or billions of parameters. Wow.

    Silly question, when we say "complex" constants at 3:48, do you mean complex numbers?
    If so, how are real numbers insufficient for describing quantum states?

    • @garlicpress6121
      @garlicpress6121 5 лет назад

      She does mean complex numbers. You definitely could also describe quantum states using Real numbers as well. You would simply represent a complex number of the form (a + bi) as an element of R x R, as they are equivalent as vector spaces. The use of complex numbers however lends itself to a more compact notation, as well has making some of the mathematics easier (arguably) to work with.

    it will be possible to solve challenges regarding P versus NP about time usage in physical world. easier way to solve the problem is ignoring time and adjusting it as a field.

    I think here's what I understood; Each additional electron in a molecule doubles the complexity of calculation for a binary computer, on the other hand each additional qubit sort of doubles simultaneous computational capability of a quantum computer, there for quantum computers should improve our ability to study molecular models beyond the capabilities of traditional computers.

      resulting in finding better materials for every aspect of our lives, medicine and maybe even produce super conductive materials to build even more powerful quantum computers.

    I'm still not really understanding the hardware. What does a cross-sectional TEM look like? How many terminals go into the device? Are there any passives or traditional transistors onboard the IC? What is an example of one line of code that can be executed?

      I don't think they would give out the information about the hardware so easy. As for the language, I think it will be an abstraction of Python like others are doing.

    I have an idea for a simulation I want to build in cirq but I barely know where to get started and my AI aren't multimodal enough to help yet.
    You guys have lots of hardcore fundamentals and extreme high level concepts but very little on experimental practical implementation.
    Need more videos on making useless things with quantum circuits.

    I am very impressed by a so smart idea. If the quantum chip (you can hold into the palm of your hand) can truly simulate all the job performed by the big computer quantum artefact (with million of cables and connexions), so this big hardware is truly no more necessary to run a computer quantum. And also there is no more any risk of true atom manipulation. I am waiting for the next videos for more details. Thanks for sharing!

    No one is asking how to make a quantum computer. What we want to know are what are it's current applications? How much is it being used in the market? What kind of problems is it currently solving? No one seems to answer any of these.

    You guys should implement cirq into a Minecraft mod that has you building and programming your own redstone quantum computers.
    Not even joking, if you want young people to start learning this stuff as early as possible then gamifying it is the best way forward.
    You should already know this after the success of Ingress.

    Isn't spin angular momentum the actual quantity used to represent the information rather than the electron levels? I mean we can work with electron levels but then we will have to treat entire atoms as our quantum objects because individual electrons don't have quantized energy states as such. And as far as I know(I am a CS undergrad, so I don't know much ), Hydrogen is the only candidate for such a quest, because we cannot even control the quantum properties of Helium as of now. And I don't think we will be using Hydrogen for this, owing to its other classical chemical properties.
    I don't know if there is a flaw in my direction of thinking? Please clarify. I also have read of a research where they manipulated entangled photons(for studying teleportation, as far as I remember). So, I think since they can be manipulated, they are also good quantum candidates.
    Please correct me if I am wrong. @googlers

    • @danielsank5094
      @danielsank5094 5 лет назад +1

      Superconducting qubits, the devices we use at Google, are not individual atoms. They are macroscopic circuits, made of superconducting metal (usually aluminum). The quantum states are various levels of resonating voltage/current in the circuit. So as you can see, our quantum bits are not spin angular momentum.
