    Why the NSA Wants a Quantum Computer, with Brad Templeton

    Most people know or remember from school that underneath it all reality is not based on billiard balls and things that match our experience in the physical world, but on a system called quantum mechanics. And the rules of quantum mechanics are rather strange and not very intuitive to us and so they don’t act like the higher level rules that we’ve built computers on so far. So there’s a bunch of research to study whether or not you can do things in quantum mechanics that perform computation in ways that we can’t do at the level of mechanical systems or electronic systems that we use. In particular it seems…

    Andrew Fursman: Digital annealer — A stepping-stone to quantum computing

    My name’s Andrew Fursman. I’m the CEO of 1QBit. There are fundamentally different paths that these companies that are producing quantum hardware are going down. The two biggest distinctions that you see are between what’s known as the circuit model of quantum computing, where we build the kind of gates that we see in classical computers, and something that’s more of a natural computing paradigm, known as quantum annealing where you basically think about a system that’s more like a natural system that evolves into a low energy state that answers these optimization problems. And so what we’ve seen is that there have been a pretty sharp divide between people…

    Landmark in quantum computing

    A team of Australian engineers and physicists have claimed a world first, the creation of a single atom quantum bit in a silicone chip. The work, published in Nature Magazine, is the fundamental requirement for a revolutionary piece of hardware, the quantum computer. Team leaders, Doctor Andrea Morello and Professor Andrew Dzurak and the main experimental author, Jared Pla, are based at The University of New South Wales in Sydney. Modern computers store information as bits which can be either zero or one to create a binary code.   These bits are realised using transistors or other devices on a silicone chip.   Now the power of modern computing comes…

    Quantum Computing with Networked Ion Traps

    An ion is a charged atom. Here we see two of them: a calcium and a strontium ion. They are superb controllable quantum systems, and we’ll see we can store information into either one. Suppose our strontium is initially in state zero. We can apply a pulse of energy to switch it to state one. Later, for readout, we can use a laser that would have no effect on state zero, but our ion in state one will absorb energy and then emit it back as a photon, a particle of light which we can detect. Let’s zoom out. We see gold strips below. These produce electric fields holding our…

    Can you explain Quantum Computing?

    I kind of think of like, Schrödinger’s cat, but the the cats inside a computer I guess it kind of sounds like something from a James Bond film, like something with a lot of ice Computing, like software design or something like that? Umm, is it kinda like quantum physics in space, but in a computer? it’s to the number of atoms to the power of 2 I’ve just googled it, so.. according to Wikipedia, quantum computing is a quantum mechanical phenomenon so ahhh yeah, I know everything now. Okay, let me have a go at it. A quantum computer is a machine that processes quantum information. So what is…

    What Is Quantum Computing?

    In previous videos I was talking about elementary particles, fundamental forces and many more things about quantum world Then some of you guys asked me, why are we worrying so much about these tiny particles Whey are we dumping bullions of $$$ to instruments like LHC So, as an answer to all these questions, today I’m going to talk about very real and amazing machine we could build with knowledge of quantum realm All the computers are made with silicon transistors They are continue to be smaller and powerful But there is a physical limit to this technology In this kind of circuit, if we make conductors too close to…

    S. Korean quantum computing scientists working on next-generation networks …

    now countries around the world are racing to develop a supercomputer based on quantum physics and South Korean researchers are really on the cutting edge of developing innovative ways to turn this transformational tech from theory as it currently is to reality Oh Sooyoung with more South Korean researchers are working on the building blocks of supercomputing networks that are hundreds of thousands of times faster and more secure than present-day technology quantum computing researchers at Korea Institute of Science and Technology have develop ways to use diamond structures to generate qubits normal computer store and send data in binary form as either ones or zeros however quantum computers use…

    Quantum Computing – The World of the Future – Extra History – #6

    And so here we are at the end with one last question. How will quantum computing change our lives? if our desktops and our phones are not going to be quantum machines any time soon what will the quantum revolution mean to us? Richard Feynman once said you can’t truly model a quantum universe on a non quantum machine and the ramifications of that are profound. Optimists posit that quantum computing will revolutionize everything from engineering to medicine, consider the field of chemistry if we could model things more accurately at the molecular and quantum level we could better simulate how chemicals interact with the human body. We could better…
