Towards experimental classical verification of quantum computation

2024 · Quantum Science and Technology

Abstract With today’s quantum processors venturing into regimes beyond the capabilities of classical devices, we face the challenge to verify that these devices perform as intended, even when we cannot check their results on classical …

A universal qudit quantum processor with trapped ions

2021 · arXiv (Cornell University)

Today's quantum computers operate with a binary encoding that is the quantum analog of classical bits. Yet, the underlying quantum hardware consists of information carriers that are not necessarily binary, but typically exhibit a rich …

How much is the fork? Fast Probability and Profitability Calculation during Temporary Forks

2022 · Companion Proceedings of the Web Conference 2022

Estimating the probability, as well as the profitability, of different attacks is of utmost importance when assessing the security and stability of prevalent cryptocurrencies. Previous modeling attempts of classic chain-racing attacks have different drawbacks: they …
