A comment on"Factoring integers with sublinear resources on a superconducting quantum processor"

T. Khattar, N. Yosri·Jul 18, 2023

Quantum computing has the potential to revolutionize cryptography by breaking classical public-key cryptography schemes, such as RSA and Diffie-Hellman. However, breaking the widely used 2048-bit RSA using Shor's quantum factoring algorithm is expect...

Dissipative phase transitions and passive error correction

Yu-Jie Liu, S. Lieu·Jul 18, 2023

We classify different ways to passively protect classical and quantum information, i.e. we do not allow for syndrome measurements, in the context of local Lindblad models for spin systems. Within this family of models, we suggest that passive error c...
