@@galihindra5901 The more advanced explaination would be that Bitcoin wallets varify their identities using digital signatures generated with an elliptic curve, since quantium computers can easily compute discrete logarithms, this signature protocol is effectively broken, and anyone in possession of a sufficiently strong quantum computer could impersonate any bitcoin wallet they wanted by cracking the private key and generating their own signatures.

awesome video. great to see videos that go past the usual "qubits can be both 1 and 0 at the same time".

[@d3solace]

At 4:01 Dave states that the Controlled Not gate is shown as containing an "amersand symbol", when the diagram displayed contains an @ (at sign) not an ampersand (&).

[@d3solace]

Examples from the Cirq docs contain @. No worries, just commenting this here for the curious.

[@mattcall90]

correct

[@dreyplatt5328]

I get the arroba and ampersand confused all the time.

[@truedreams1]

Just to further confuse you.

[@louistech112]

This is some ground breaking bleeding edge of tech learning here

[@truedreams1]

Quantum processors aren't binary, which means you code doesn't always have to be boiled down to binary logic, you can instead build the circuit logic in your Cirq code (with the limitations mentioned). So if you're building for example a rock/paper/scissor game with an regular binary processor that would take many steps and computation steps, but a quantum processor would do that in one processor stroke (or whatever they're called in quantum world- quantum strokes?), as long as the logic could fit in to the circuit.

[@nigeljohnson9820]

How about explaining what the gates can do! There is so many new terms which are being used without first being defined, by the end you might as well be explaining in an obscure dialect of Eskimo.

I want some more quantum computing videos!!! Google make more videos explaining and practical uses of quantum computers please!

[@BigyanChap]

What is Hardamard gate? What is Control-NOT? Neither Cirq nor Qiskit is explaining these kinds of stuffs and directly jumping into the circuit. Where can I find the documentation?

[@t3hPoundcake]

I'm starting to get deeper but I still am looking for an explanation (no matter how in depth or scientific and high level to understand) of how Google or IBM takes this Python syntax and interprets/compiles it to manipulate a physical qubit existing on a quantum chip. Is the Python code literally compiled and interpreted by the quantum machine natively like when you compile a C++ program on a windows machine? Or is this Python code just a tool for helping them physically configure a quantum processor? Does anyone have more resources on how we go from this code or Qiskit code to execution on a quantum processor?

[@fu2201]

Hmmm the quantum circuit looks a lot like the pentatonic minor scale.....

[@MrYingding]

I don't get it. With the Python GIL in place, Python doesn't seem to be a good language for quantum computer? Or quantum computer is just suppose to be lightening fast with no need of parallel tasks?

[@alxjones]

Python is just the language used to build the circuits. In the end, the circuit is compiled to a quantum assembly language (QASM) to be run on real quantum hardware. The only thing that relies on Python's performance capabilities is the construction of the circuit object, which is fairly simple even with hardware constraint checking, and the running of the simulator, which is going to be slow on anything. Python is a popular language among scientists because it's easy to learn and use, so it seems like a natural choice for this application, even if it's not the one I personally would have chosen.

[@alexandrumoraru4286]

Are you going to provide support for Julia programming language?

[@CraigGidney]

At this time, there are no plans to port Cirq into languages besides Python.

[@fathiyul]

Hello, I'm new here. I don't quite understand how my PC could run the quantum computation program without having quantum computing processor in it. Anyone? Also, since 2 years have passed, have we surpassed the NISQ era? thanks in advance

[@alxjones]

No. As far as I know, 127-qubits is the current maximum, achieved by IBM in November 2021. The general rule is that 10 to 100 noisy qubits equate to 1 "perfect" qubit, so this means our best possible error-corrected computer could theoretically have somewhere around 1 to 13 effective bits. Realistically, there's more to it than just the number of qubits, so I don't think we're really even capable of that. NISQ isn't particularly well-defined, but to get an idea, Shor's algorithm requires on the order 10^3 qubits, which if error corrected, corresponds to 10^4 to 10^5 noisy qubits at best. This video (7:33) estimates it closer to 10^6, or 100,000 noisy qubits. IBM has a lofty goal of a 1,000-qubit processor by 2023 and 1,000,000-qubits by 2030, so even if they stay on track, it will be quite a few years before we're definitively out of NISQ.

[@mahogs9]

I don’t know a whole lot about programming or computers, so this idea might be completely stupid. Is it possible that quantum computers might not replace standard computers? Instead, can we combine quantum computers with blockchain to develop a ledger faster than a traditional computer can make, but have a traditional computer use that ledger?

[@johnkelfy7256]

We said the same thing on gpus. Plus I don’t see people cool their system to literallly kelvin -9.2 just to watch ray tracing he*ntai

[@unlockwithjsr]

I just think everything is possible

[@alxjones]

I don't know why blockchain had to enter this discussion, but generally, yes. We already know that there are things classical computers do better than quantum, cost and efficiency among them. Hybrid classical-quantum architectures seem to be the best of both worlds, though we are quite far from a consumer QPU. Until then, we'll likely be limited to cloud platforms like GCP for hybrid computing tasks.

[@jajwarehouse1]

Ah, quantum computers; the pursuit of adding more hardware to correct the errors that are generated by the hardware before the hardware outputs random results depending on how the hardware feels at the moment, that then have to be quantified by the billions to see which of the possible results were created the most so that we may assume it is the most probable correct answer. I do not want to dismiss quantum computers altogether, but I have yet to see anyone show a single example of a problem that a quantum computer has solved that could easily be solve by a normal computer, let alone a problem that a normal computer could not possibly solve.

[@alxjones]

This is the idea of quantum supremacy. In the most technical sense, this has been shown, but not in any useful sense. It's extremely reasonable to be skeptical of quantum hardware until someone has build a significant post-NISQ processor, but it has been mathematically proven that some quantum algorithms beat the best known classical ones under the assumption of the existence of said hardware. The fact that the results are random is actually a non-issue in many cases. Many algorithms are hard to solve but easy to check, so we can just verify if the solution is correct and re-run if not. For example, factoring is hard but multiplying is easy, searching an array is hard but resolving an index is easy, solving matrix equations is hard but multiplying matrices is easy, etc. Retry logic is constant-order complexity, so any quantum speedup effects are still there (though possibly requiring larger problems to see real effects).
