Quantum Pseudorandom Error-Correcting Codes
Min-Hsiu Hsieh, Shogo Yamada
Pseudorandom error-correcting codes (PRCs), introduced by Christ and Gunn [CRYPTO 2024], are classical error-correcting codes whose codewords are computationally indistinguishable…
Black-Box Separation Between Pseudorandom Unitaries, Pseudorandom Isometries, and Pseudorandom Function-Like States
Aditya Gulati, Yao-Ting Lin, Tomoyuki Morimae +1
Pseudorandom functions (PRFs) are one of the most fundamental primitives in classical cryptography. On the other hand, in quantum cryptography, it is possible that PRFs do not exis…
Pseudorandom Function-like States from Common Haar Unitary
Minki Hhan, Shogo Yamada
Recent active studies have demonstrated that cryptography without one-way functions (OWFs) could be possible in the quantum world. Many fundamental primitives that are natural quan…
Quantum Unpredictability
Tomoyuki Morimae, Shogo Yamada, Takashi Yamakawa
Unpredictable functions (UPFs) play essential roles in classical cryptography, including message authentication codes (MACs) and digital signatures. In this paper, we introduce a q…
Scaling-up Memristor Monte Carlo with magnetic domain-wall physics
Thomas Dalgaty, Shogo Yamada, Anca Molnos +8
By exploiting the intrinsic random nature of nanoscale devices, Memristor Monte Carlo (MMC) is a promising enabler of edge learning systems. However, due to multiple algorithmic an…
Anomalous change in the de Haas-van Alphen oscillations of CeCoIn at ultra-low temperatures
Hiroaki Shishido, Shogo Yamada, Kaori Sugii +3
We have performed de Haas-van Alphen (dHvA) measurements of the heavy-fermion superconductor CeCoIn down to 2 mK above the upper critical field. We find that the dHvA amplitude…
