Quantum Break – Quantum Computers Breaking Modern Encryption
According to a scientific paper published in December, Chinese researchers have claimed to have found a way to break the most common form of online encryption using current-generation quantum computers, years before it was expected to be a threat. The method could be used to break the RSA algorithm, which underpins most online encryption, using a quantum machine with just 372 qubits, said the researchers from various academic bodies and state laboratories. IBM has said that it’s 433 qubit Osprey system, the most powerful quantum computer to be publicly unveiled, will be available to customers this year. Computer security experts are divided over the research, with some saying it is sound but others adding that it may be beyond the reach of current quantum technology.
The Chinese researchers claim to have used their algorithm to factor a number with 48 bits on a quantum computer with 10 qubits but have yet to have the chance to scale it up to work on a more extensive system. While the research has raised concerns over the potential threat to online encryption, it is essential to note that the technique has not yet been tested in practice, and its effectiveness remains uncertain. Additionally, even if the research claim proves unfounded, it highlights the race to find a way to break encryption using quantum computers far earlier than many had expected. Quantum computers can revolutionize fields such as healthcare, finance, and transportation, but their development has also raised concerns over the potential risks to data security.
What do you think about this development? And could the research ever become a real threat?
