Cool bruh. But have you ever tried DMT?
Isn't a quantum computer the same as a regular computer but instead using the spins of say a photon to represent a bit unlike conventional computers which use a voltage?
…So really we should call them QPU's ? Quantum Processing Units
Loved the fact that you just let the expert talk. Made the video very informative and very precise.
1:26 BUT GPU's are not advertised to run on faerie dust!
Well it's obvious that nothing is going to become of quantum computing.
So what will people actually do with a quantum computer?
I would want to know concrete examples and why you would choose the quantum computer to do exactly that thing.
If sciense fabricate a new material that could allow a new CPU with the same advadages BUT to work in normal computers temperature we will have Quantum computers.Although a very importand question is not asked so far.If we can create a so powerfull CPU, what could happen if we overclock it ?
This is probably the best short, nontechnical video on quantum computing that I've seen
What cryptographic protocol is best suited for IoT? Directed Acyclic Graphs? Hash tables? Blockchains?
So if quantum CPUs don't conceptually "multi-core" (to a power rather than linearly) with additional qubits, then how exactly do QPUs work? I know roughly how they work, quantum logic gates, superpositions of superpositions, entanglement, interference and so on. I'm also familiar with applications such as optimization (traveling salesman) and modeling of quantum, or natural systems (molecules, fundamental particles, etc). My background is physics/finance not computer science. From a physics POV I think of superposition and especially superposition of superpositions (e.g. young's double slit) as implying multiple processes simultaneously – so the electron or photon exhibits wave-particle duality and in some sense travels all possible paths before deciding upon a definite outcome upon observation, an outcome that is influenced by past and future events as well as the present (evidenced by the clearly defined interference patterns). This is analogous to qubits being 0 and 1 at the same time (a superposition) but that means the value could be anything between 0 and 1 until we measure it. Does adding qubits not allow the system to solve branching math problems by branching out probabilities (superpositions of superpositions) in a similar way to an electron in young's double slit? That is to say when you ask a QPU to perform an action the qubits in a sense know the answer and all possible answers to the question upon input, the perceived delay is just how long it takes the observer (measurement, output) to experience the output in their reality.
Its scary…. computers in the 70's were size of a room, they ran off binary. Look at where we are now with binary computers.. In 40 years time we will have quantium computers inside of what we call a laptop now.
Why are they still so big they should be able to start making them smaller thanks to higher-order topological insulator and time crystals. These things fix the high temp super conductor problem and coherence problems respectively
well the title of this video is Current State of Quantum Computing not Introductory Course to Quantum Computing isn't it? He actually answered the question. I like this guy. He sounds like my (American) professors and makes a lot of references to industry.
😇 Thank you for all your beneficial video, it certainly is greatly valued and I definitely value your hard work !👍
When will you be able to break SHA256 encryption?
The current state of quantum computing is a superposition. There's no way to know with certainty where it will be going.
Why does the light make him look so orange
can someone expand on the robustness to noise issue he mentioned? I remember hearing in another video, maybe a computerphile video, that there are two types of quantum computer… one of them gives correct and consistent answers every time, while the other one is somehow not a "true" quantum computer because the process is somehow subject to error and inconsistency. So you don't always get correct answers. Would that be the noise they're referring to? and would that mean that the type of quantum computer he's referring to cannot be used for problems that need a single specific and accurate answer like cryptographic problems? are we ever going to reach that level of computing?
Could a quantum computer be used (better than regular computers) for chess?
What does the data set you feed a quantum device with look like? I mean, is there a math treatment like a DAC between the two interfaces or can it deal with binary logic just as well as the electronic ones?
I would have liked some discussion on D-Wave's quantum computer. Aren't they planning on making a 2000 qubit quantum computer? Seems to me that D-Wave is worthy to be discussed.
This was not explained very well.
I notice that I don’t use the letter Q in my life as much as I now realize that I have been needing to.
Positively life changing
Yeah, well I "work" for Quantum Silicon in Alberta, and we'll have 500 qbits in a year. Room temp. Birches
D.Wave is simulated quantum computing and they know it !
