Quantum Computers Explained: How Quantum Computing Works

Quantum computers use the principles of quantum mechanics to process information in ways that classical computers can’t. They rely on qubits, which can exist in multiple states simultaneously, allowing for more complex computations and parallel processing. Unlike classical bits, which are either 0 or 1, qubits can be in a state of 0, 1, or both simultaneously (superposition). This allows quantum computers to process a vast amount of information at once. Qubits can be entangled, meaning the state of one qubit can depend on the state of another, no matter how far apart they are. This correlation can be used to perform complex calculations more efficiently. Quantum computers could break widely used encryption methods (like RSA) due to their ability to factor large numbers quickly. This has led to the development of quantum-resistant encryption algorithms. They can simulate molecular interactions at a quantum level, significantly speeding up the drug discovery process by predicting how different compounds will behave. In this video, we have explained quantum computing in simple words and explained how quantum computers work.

  1. Trump just put project star gate in play 500 billion dollar operation for an AI infrastructure made in America buying up acres of land for the facilities that is more than likely going to house quantum computers the world is definitely becoming more and more like those futuristic movies we used to watch

  2. I wouldn't invest a dime in this BS.
    A simple 100 question multiple answer test that consists only "yes" or "no" or "maybe" check boxes for each question.
    Anyone can score 33% on this test without even reading the questions.
    But your million dollar quantum computing can score 100% in record time.
    And the way you do it is by checking yes and no and maybe all at the same time for each question.
    We look at the answers and sure enough the correct box as been checked for the correct answer by each question.
    Never mind two wrong answers have been checked by each question simultaneously.
    I think this is smoke and mirrors to get grant money and donations.
    No one is able to explain a quantum computer in simple terms or build a mechanical model that could perform the simplest task.
    As far as Google and their work ethics, they can't even control spam comments or web sites that have gamed their search engine for top rank.
    I'm just not convince this is an honest representation of good science.

  3. I feel like they somehow kinda found a way to make a digital "ATOM," in a sense!…..
    Like the atom is always spinning at a phenomenal rate so is this umm……….. Algor….. something 😂😂😂😂😂. Idk
    Sounds good tho right!!????😅😅😅

  4. This is how I explain quantum processing… if 1 equals a processes in a grid…
    80s 1 / 90s = 2×2 / 00s = 9×9 / 10s 64×64 / 20s 512×512 / latest chip 999x999x999 / quantum computer = 999x999x999 at 1pm…. uses 4d space to run calc the old grid on x and y axis… plus the addition of z axis for 3d which is the latest chip… so the processor is like a cube… then add time to it.. meaning it can exist in multiple states being both on and off at the same time

  5. I understand the theory. But what I dont understand is how to actually make the computer work physically. How to control each eletron's state as what you want? How to control if you want two qubits to entangle or not? How do you interpet all 0001 0000 0010 etc…into something meaningful?

  6. Yeah yeah, 0 and 1 at the same time. We know that. Heard it one thousand times. Please not again.
    How does a complex interference pattern with only one result answer a question? What type of question is it and how is the question fed in to the quantum computer
    and the result viewed?

  7. All these videos about "How Quantum Computing Works" miss one major point – how do the computers read the calculated values? A Qubit in superposition collapses when observed or measured so how do they obtain a result from a computation? Surely the computer would only get the result of the current state at the point in time the measurement was taken?

  8. QC is both dangerous and great for us at the same time. On one hand, it will cure a lot of diseases, but it will also speed up technological advancement weekly instead of years and will give “robots” the legitimate consciousness it needs to be just like the human-like droids we see in Star Wars content. Our missing link right now is achieving more authentic consciousness rather than really good programing that appears to be consciousness. Being in a quantum state is to be constantly in flux and to be able to consider things and go in any direction. In a way, human minds already use “qubits” in their consciousness.

  9. If quantum computing seems to have all these challenges with having to operate at subzero temperatures, and only able to process a few cubits at a time, why don’t computer scientist just focus on making multi state computers using existing technology to develop the algorithms that can allow us to go past the current binary framework of zeros and ones and onto multi states such as 0123 etc.?
