What is quantum resistance in the context of cryptographic protocols, and how does it affect Bitcoin?

'Quantum resistance is the ability for cryptographic protocols to remain secure in the presence of fast quantum computers.'

Bitcoin can continue using its currently highly space efficient cryptography while it remains safe, and then upgrade to post-quantum cryptography when it looks like it’ll soon become necessary.
