Questions & Answers

Q: What is quantum supremacy?

Quantum supremacy refers to the point when a quantum computer can solve a well-defined task much faster than any known classical computer algorithm.

Q: Can classical computers eventually do everything quantum computers can do?

Yes, classical computers can eventually do everything that quantum computers can do, but exponentially slower.

Q: How is the term "efficiency" important in computer science?

Efficiency refers to an algorithm's scaling behavior, with an aim for polynomial scaling as input size increases, rather than exponential scaling.

Q: Does quantum supremacy require error correction?

No, quantum supremacy does not require error correction. It only aims to refute skeptics who claim that classical computers will always outperform quantum computers.
