Researchers from Shanghai University have breached encryption algorithms commonly used in banking and cryptocurrencies using a quantum computer.
They employed quantum annealing and targeted algorithms crucial for advanced encryption standards (AES) used in cryptocurrency wallets.
While AES-256 is considered safe, researchers warn that quantum computers could soon become a real threat to encryption.
Environmental factors, hardware issues, and the challenge of creating a single attack algorithm for multiple systems make full-scale quantum hacks difficult for now.
