Did Google really achieve Quantum Supremacy?
Why is this a big leap for us?
Importance of Quantum Noise
meaning its ability to maintain the superposition state — can fall apart due to the noise coming from the environment around the qubit. Noise can arise from control electronics, heat, or impurities in the qubit material itself, and can also cause serious computing errors that may be difficult to correct.
Google's quantum computer tackled a task called a random circuit sampling problem. In such a problem, after a series of calculations each qubit outputs a 1 or 0. The aim is to calculate the probability of each possible outcome occurring.Was able to find the answer in just a 3 minutes – a task it estimates would take 10,000 years on the most powerful supercomputer.
