- 1Quantum Computer Could Crack Internet Encryption in Days, Study SaysโA Quantum Computer Could Crack Major Internet Encryption in Just 3 Days, Study Suggests
A new study suggests a sufficiently advanced quantum computer could break RSA encryption, the technology securing much of the internet, in as little as three days. The claim renews debate over how urgently governments and companies need to adopt post-quantum cryptography before quantum machines become powerful enough to threaten banking, messaging and other secure communications.

French quantum computing company Alice & Bob announced a record-low estimate for the quantum resources needed to break internet encryption. The company says its cat qubit approach dramatically reduces the number of physical qubits required to run Shor's algorithm against RSA cryptography. The claim is drawing attention from cybersecurity experts assessing how soon quantum computers could threaten current encryption standards.

An interactive educational project called Cryptostream lets users explore the evolution of encryption, from ancient ciphers such as Caesar to wartime machines like Enigma, and on to modern systems including AES, RSA, ChaCha20 and post-quantum cryptography. It uses animations and visual explanations to make cipher history and the science of secret-keeping accessible to a general audience.
- 4Alice & Bob estimate cat qubits could factor RSA-2048โOur estimate for factoring RSA-2048 with cat qubits: pushing the frontier between size and speed
French quantum computing startup Alice & Bob has published an estimate for factoring RSA-2048, the encryption standard widely used to secure online communications, using its cat qubit technology. The company says its approach pushes the frontier between the size and speed of quantum machines needed to break RSA encryption. The claim draws attention because factoring RSA-2048 with quantum computers would threaten much of today's cryptographic security.

French quantum hardware startup Alice & Bob published a new resource estimate putting the cost of breaking RSA-2048 far below previous assumptions: roughly 22,593 cat qubits running for about three days. The estimate also says factoring the elliptic-curve discrete logarithm on secp256k1, the curve protecting Bitcoin, would take about an hour on at most 29,588 qubits. Security researchers are weighing the implications for encrypted traffic and cryptocurrency, though such hardware does not yet exist.

A new write-up by Khalid Hamadeh explains how the pi table used in the RC2 encryption algorithm was originally generated. RC2, a cipher designed by Ron Rivest in the 1980s for RSA Data Security, has long had a curious internal table of values derived from pi whose exact construction was undocumented. The article draws attention among cryptography enthusiasts discussing the historical details of the algorithm's design.
