How are advancements in quantum computing hardware poised to revolutionize cryptography?

Quantum computing is a burgeoning field that promises to vastly expand the capabilities of traditional computing through the use of qubits and entanglement. As quantum computers inch closer to practical implementation, they threaten to undermine the security frameworks that are foundational to contemporary cryptography, particularly those relying on factorization and discrete logarithmic problems. How will hardware developments in quantum computing redefine our approach to encrypting data and securing communications, and what strategies might developers employ to pre-emptively address these changes in cryptographic infrastructure?
