Quantum Computers and Applications Over the Next 5 Years | NextBigFuture.com

This article has information from the quantum computer expert John Preskill. We are going to get more and better quality qubits with lower error rates. The overhead cost for error correction improves as gate error rate declines. The Google Quantum supremacy demonstrations confirmed the quantum world has huge computing resources. We are in the noisy qubit era. We can explore heuristic quantum algorithms. We might get near-term quantum advantage for useful applications but this is not guaranteed. Near-term algorithms should be designed with noise resilience (noisy qubits) in mind. We will get good truly random number generation and will explore
