Stateful hash-based signature (HBS) schemes provide quantum-resistant digital signing for software and firmware. Standardized by NIST in SP 800-208, LMS/HSS and XMSS use one-time keys to ensure strong ...

Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines. The codes were applied to IBM ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

Quantum computers offer great promise for cryptography and optimization problems. ZDNet explores what quantum computers will and won't be able to do, and the challenges we still face. Read now ...

Real-world computers that can speedily crack even the most secure codes are within grasp thanks to recent advances that will allow for so-called fault-tolerant quantum computers, according to an ...

Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography. The most recent email you sent was likely encrypted ...
