1. how do you know it got the right answer? How can you check it if no other computer can do the calculation? 2. The explanation was total nonsense and did not come even close to explaining how quantum computing works. 3. Only specific types of problems can be solved using quantum calculations... and these need a special form of math and programming language to do so... so the practicality of quantum computing is still questionable. 4. how did they solve the greatest problem with quantum computing? i.e. physical random errors at the lowest atomic level in the circuits. 4. quantum computing has nothing to do with "multiple universes", that is total BS.

1. “How do you know it got the right answer?” This is a legitimate question for quantum supremacy claims. Typically, researchers validate quantum computations by comparing the output to a simplified version of the problem that classical computers can simulate for smaller cases. For problems too large for classical verification, statistical sampling or theoretical models are used. The challenge lies in establishing trust in results when no classical benchmark exists. 2. “The explanation was nonsense and didn’t explain how quantum computing works.” • Explaining quantum computing succinctly is challenging. Quantum computers leverage qubits, which exist in superpositions of states (both 0 and 1 simultaneously) and are entangled, meaning the state of one qubit is linked to others. Operations exploit these properties to perform parallel computations. If the explanation lacked clarity, it might be because it’s difficult to convey this complexity in lay terms. 3. “Only specific types of problems can be solved using quantum calculations.” • Correct. Quantum computers excel at particular tasks like factoring large numbers, optimisation, and simulating quantum systems, but they are not universally faster than classical computers. For general-purpose computing, classical computers remain dominant. 4. “The practicality of quantum computing is questionable.” • Practicality is still an ongoing debate. Current quantum computers face issues with scalability, error correction, and coherence (maintaining qubit states long enough to compute). Google’s Willow chip represents progress, but we are far from fault-tolerant, large-scale quantum computing. 5. “How did they solve physical random errors?” • Error correction is a major hurdle in quantum computing. Techniques like surface codes and error-correcting algorithms can identify and mitigate errors, but these approaches often require many physical qubits to create one logical qubit. Progress has been made, but error correction remains a limiting factor. 6. “Quantum computing has nothing to do with ‘multiple universes’.” • The reference to “multiple universes” is likely based on the many-worlds interpretation of quantum mechanics, which some use as an analogy to explain superposition. While this interpretation is intriguing, it’s not a requirement for quantum computing to work. The computation relies on the mathematics of quantum mechanics, not specific interpretations.

Do you experts know how encryption works? Md5, sha256...? Heard of those? Because it seems you havent let me answer all your questions - encryption takes forever to crack and 1sec to make. If they have an answer, then it takes a normal computer also 1 sec to check if it is correct, it doesnt take trillion years like it would if they wanted to crack it

So far, one of the best explanations I have seen and heard. I am still not sure I understand how the superposition states are read. Are they converted to standard binary in any case? Great job, as always on the hunt for homework well done.

The qubits stay in a superposition until it is measured at that point the superposition (called Wave-particle duality) collapses and you have 1 state (either a 1 or a 0).

Sorry, but the explanation is not even close to how quantum computing works. And it's not clear at all. It just waves around terminology as an explanation without explaining why quantum computing will not be used for practical purposes for decades, e.g. the random errors that occur at the subatomic level when particles are entangled.

Interesting how quantum computing catches all the shine whereas photonic computing is already being used in real world applications across the world. Fault-tolerant quantum computers are still a long ways off and the NISQ systems we have today are only useful for very, very specific applications. Also with the world trying to be more energy efficient in just about everything: Photonic systems are more energy efficient than our current electronic systems while quantum computers need their own powerplants to run.

Luckily that's not how entangled particles work. They're only entangle when not observed, once they are observed the entanglement is broken. Also there's currently no way to transfer information with entangled particles. So we are safe from an entangled quantum big brother for the foreseeable future

@@phazephusion Hmmm, ever read J. Gregory Keyes' "Age of unreason" series? This video made me think of aetherscribers. If you have one particle in one computer, and another particle in the other, no-one's going to be observing them. Get enough of them and you can observe the effects of their motion. You can't do it now, but if someone's determined enough, a way will be found.

This 'expert' can wave her hands like a ventilator that doesn't mean she answered the question if Google cracked a key problem in quantum computing. Just telling things that you can easily find on the internet should not make you an expert. And I say that if Google would have cracked that big a problem their stock would have substantially risen. It has not so this is not that big a deal. And more. As a non expert I say that the number of qbits was far to small to be of any practical use.
