Physical vs. logical qubits and error rates

Preston and Charles dive into the fundamentals of quantum computing, its transformative applications, and the looming threat it poses to Bitcoin encryption.

They break down the distinction between physical and logical qubits, real-world use cases, and the exponential progress in the field. With timelines tightening, they call for urgent collaboration across the Bitcoin and cryptography communities to prepare for a post-quantum world.
