Quantum Cryptography and Hardness of Non-Collapsing Measurements

Tomoyuki Morimae, Yuki Shirakawa, Takashi Yamakawa · 2025

One-way puzzles (OWPuzzs) introduced by Khurana and Tomer [STOC 2024] are a natural quantum analogue of one-way functions (OWFs), and one of the most fundamental primitives in ''Microcrypt'' where OWF…

Hardness of Quantum Distribution Learning and Quantum Cryptography

Taiga Hiroka, Min-Hsiu Hsieh, Tomoyuki Morimae · 2025

The existence of one-way functions (OWFs) forms the minimal assumption in classical cryptography. However, this is not necessarily the case in quantum cryptography. One-way puzzles (OWPuzzs), introduc…

A New World in the Depths of Microcrypt: Separating OWSGs and Quantum Money from QEFID

Amit Behera, Giulio Malavolta, Tomoyuki Morimae, Tamer Mour, Takashi Yamakawa · 2024

While in classical cryptography, one-way functions (OWFs) are widely regarded as the "minimal assumption," the situation in quantum cryptography is less clear. Recent works have put forward two concur…

Founding Quantum Cryptography on Quantum Advantage, or, Towards Cryptography from $\mathsf{\#P}$-Hardness

Dakshita Khurana (UIUC), Kabir Tomer (UIUC) · 2024

Recent oracle separations [Kretschmer, TQC'21, Kretschmer et. al., STOC'23] have raised the tantalizing possibility of building quantum cryptography from sources of hardness that persist even if the p…

Exponential Quantum One-Wayness and EFI Pairs

Giulio Malavolta, Tomoyuki Morimae, Michael Walter, Takashi Yamakawa · 2024

In classical cryptography, one-way functions are widely considered to be the minimal computational assumption. However, when taking quantum information into account, the situation is more nuanced. The…

Symmetric Toda, gradient flows, and tridiagonalization

Anthony M. Bloch, Steven N. Karp · 2023

The Toda lattice (1967) is a Hamiltonian system given by $n$ points on a line governed by an exponential potential. Flaschka (1974) showed that the Toda lattice is integrable by interpreting it as a f…

Experimental Research of the Diffraction and Vavilov-Cherenkov Radiation Generation in a Teflon Target

M. Shevelev, G. Naumenko, A. Potylitsyn, Yu. Popov · 2011

Geometry of Vavilov-Cherekov (VChR) radiation when an electron moves close to a dielectric target is in analogy to diffraction radiation (DR) geometry. In this case we may expect DR generation from th…
