Dilemma between Quantum Speedup and Computational Reliability--Overcoming Errors with Efficient Verification Methods for Quantum Computing
Yuki Takeuchi, Seiichiro Tani · NTT technical review · 2023
Quantum computers are expected to solve several problems faster than any classical computer.However, they may sometimes output incorrect answers because they are prone to errors.Therefore, to develop reliable quantum computers, it is essential to develop methods of verifying whether the outputs of quantum computers are correct.In this article, we introduce our recent research results on our verification methods.
