Using an unordered list, summarize the following article with between 4 and 8 key points.
\n\t\t\t\t\t\tWhat changes when quantum computers arrive?Sushmita Ruj, Faculty of Engineering Lead at the UNSW Institute for Cybersecurity, IFCYBER and Associate Professor at the School of Computer Science and Engineering (CSE), UNSW, Sydney, says that not all quantum machines pose a threat to current encryption methods.\u201cCryptographically relevant quantum computers\u00a0have the power to break currently used public key algorithms like\u00a0RSA and\u00a0ECDSA, which are the backbone of many communication protocols and secure applications. Much of the encryption today relies on algorithms like RSA and \u00a0 These will no longer remain secure.\u201dPost-quantum cryptography is essentially a new way of \u2018locking up\u2019 information so that even quantum computers \u2013 very powerful future computers \u2013 won\u2019t be able to gain access to it. The encryption and authentication algorithms used to keep data safe today \u2013 RSA and other common public key algorithms, for example \u2013 work well against conventional computers but could be easily cracked by more advanced quantum computers.\u201cThis has a significant impact on personal data, such as health records and credentials, as well as sensitive government and corporate information,\u201d says Ruj.Public-key systems such as RSA and\u00a0ECC\u00a0underpin secure web browsing, digital signatures, authentication protocols, and secure data exchange across supply chains. If broken, the impact would extend across providers, customers, and global digital ecosystems.Ruj says that although the exact timeline for deploying this new technology remains uncertain, the direction is clear. \u201cWith the advancement of quantum computing, the risk is pretty high. Though we might not have cryptographically relevant quantum computers for another five to 10 years, the transition process is so slow that if we don\u2019t start now, then it will be hard to change to quantum-safe systems overnight,\u201d she says.\u201cTo give some numbers, currently, we have quantum computers with a little more than 1,000 qubits; a cryptographically relevant quantum computer might potentially need around a million qubits to break\u00a0RSA-2048\u00a0[a very large digital key that is extremely difficult to crack].\u201dThe implication for risk management is significant. Even if cryptographically relevant quantum computers are years away, sensitive information encrypted under current systems today could be exposed in the future.
