Twin-Field Quantum Digital Signature with Fully Discrete Phase Randomization
, 2022 Quantum digital signatures (QDS) are able to verify the authenticity and integrity of a message in modern communication. However, the current QDS protocols are restricted by the fundamental rate-loss bound and the secure signature distance cannot be ...

Tightly Secure Lattice Identity-Based Signature in the Quantum Random Oracle Model
, 2023 We present a quantumly secure identity-based signature scheme based on the standard short integer solution problem, featuring tight security reductions in the quantum and classic random oracle models. The scheme has short signatures.

Forgeable quantum messages in arbitrated quantum signature schemes
, 2017 Recently, the concept on ‘forgeable quantum messages’ in arbitrated quantum signature schemes was introduced by Kim et al. (Phys Scr 90:025101, 2015), and it has been shown that there always exists such a forgeable quantum message for every known ...

Quantum Signature of a Squeezed Mechanical Oscillator [PDF]
Physical Review Letters, 2020 Some predictions of quantum mechanics are in contrast with the macroscopic realm of everyday experience, in particular those originated by the Heisenberg uncertainty principle, encoded in the non-commutativity of some measurable operators. Nonetheless, in the last decade opto-mechanical experiments have actualized macroscopic mechanical oscillators ...

A Hash-Based Quantum-Resistant Chameleon Signature Scheme
Sensors, 2021 As a standard digital signature may be verified by anybody, it is unsuitable for personal or economically sensitive applications. The chameleon signature system was presented by Krawczyk and Rabin as a solution to this problem. It is based on a hash then

DiLizium: A Two-Party Lattice-Based Signature Scheme
Entropy, 2021 In this paper, we propose DiLizium: a new lattice-based two-party signature scheme. Our scheme is constructed from a variant of the Crystals-Dilithium post-quantum signature scheme.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Thermally activated charge fluctuations in GaAs double quantum dots [PDF]
, 2014 In this thesis, laterally defined GaAs quantum dots and double quantum dots are investigated by means of real-time charge sensing. A quantum dot charge sensor, adjacent to the investigated double dot system, detects single electron tunneling with ...

Comment on “Arbitrated quantum-signature scheme” [PDF]
Physical Review A, 2008 We investigate the quantum signature scheme proposed by Zeng and Keitel [Phys. Rev. A 65, 042312 (2002)]. It uses Greenberger-Horne-Zeilinger (GHZ) states and the availability of a trusted arbitrator. However, in our opinion the protocol is not clearly operationally defined and several steps are ambiguous.
