Where do we go next? |The Future of Quantum Computing | QC40

[@lunafoxfire]

Nice! I was actually just doing some research on what the state of quantum computing is right now out of curiosity so the timing of this video is kinda perfect for me, lol. I'm just a regular boring classical programmer but I'm really fascinated by the potential of quantum computing.

Found a simple algorithm to decide whether a function permuts its input, or calulates new values. Example: (3,8,11,14) --> (11,3,14,8) Create balanced superposition of all inputvalues. Amplitude a = 0.5 F( a|3> + a|8> + a|11> + a|14> ) = a F|3> + a F|8> + a F|11> + a F|14> = a|11> + a|3> + a|14> + a|8> If the function permutes, outputstate is same as inputstate, just in different order. But order doesn't matter in this case. Classically you have to calculate n values "one by one" and compare them. With that, you need only one operation to check.

Are these charts available somewhere?

im fathi from morocco and im so interesting about quantum cryptography and devlopement

[@amarsinghpatil6414]

How representations happen in qubit, mean classical representation happen in base of 2 . So my question is how representation happen in qubits

[@matthewstone6620]

Thought on Quantum Computing QCI (QUBT) Thanks

[@dalton6173]

If you can simulate an are twice that of your civilization, then simulate your civilization twice and have them each simulate two of their universe and so on and so on and your one computer is now simulating billions and billions times the area of the universe we live in. Granted you won't be learning much other than possibly what will happen in your civilization also assuming the simulated simulations are 100% accurate and that each additional simulation would not slow down the larger computer.

Great video, but the amount of "ums" was quite distracting

[@chad0x]

Maybe have your slides ready before you start? Just a suggestion. Great material but it makes yo ulook :O

Too many "uh" 's, "uhm" 's and the such like

I'm glad someone has taken the time to present this topic, and that is it offered for free for everyone to listen to

[@nerdi_brilliantidea3314]

Let play game that the game would be play no more everybodi is broke when it come to the deficit of USA TWENTY EIGHT TRILLION DOLLAR DEBT SO PLEASE STOP OFFENDING KNOWLEDGE I GAVE THANK TO ALL THIS PROFESSOR FOR THIS KNOWLEDGE AND BACK ME UP FOR THE FUTURE INVENTION HELLO QUANTUM MECHANIC I HAVE MISS YOU FOR SO LONG NOW LET PLAY...

Calm down man.

[@laurenth7187]

Now, don't scream, but there is no future of quantum computing. There is no improvement there, since every device (bit, qbit...nand) is connected and inter connected by good old copper wires, which already transmit at the speed of light.

[@scigy]

Quantum computing gets its advantage from being able to perform a bigger set of logical operations efficiently, not from an ability to interact systems faster.

[@laurenth7187]

@@scigy Then it could be built with existing gate technology. Inside your Q computer you have also copper wires, therefore it's useless to have fast gates.

[@scigy]

@@laurenth7187 While a quantum computer uses existing gate technology to control some parts of it, there is no way of doing quantum computing using only that existing gate technology. For instance, it is true that you can program whether a hadamard or control-phase gate will be applied in a quantum circuit using existing classical computing gate technology (ibm qiskit does this online). This could be done by using existing gate technology to schedule to turn on a microwave pulse or turn on an interaction. However, actually performing a hadamard or control-phase gate cannot be done with only technology such as NANDs (at least efficiently and in general). Quantum computing allows an efficient access to this larger gate set (unitary rotations). Being able to simulate quantum circuits of more than say 100 qubits efficiently using existing technology would be a major breakthrough.
