Scaling Semiconductor Quantum Computers: Qubits Need to Match Classical Transistors

whurley · x · 2026-07-30

Discusses the realistic challenges of moving quantum computers toward general-purpose computing. The view suggests that achieving this would require a staggering number of qubits—roughly on par with today's classical transistors—alongside significant improvements in operating frequencies.

However, as semiconductor-based quantum computers advance, scaling them into general-purpose machines seems increasingly plausible.
