Pricing the Unprovable: Ambiguity, Turnstile Runs, and the Verifiability Discount in Crypto Protocols
Doohwi Cha, Hanhee Kim, Hyeonjun Yeo +5
Privacy-preserving protocols can repair a vulnerability without establishing whether it was exploited beforehand, even when no theft is reported and aggregate supply is protected.…
NEST: Stale-Robust Tokenized-Stock Measurement for a Crypto-Treasury LETF Stack
Doohwi Cha, Minsuk Sung, Minjae Lee +5
Tokenized equities trade while listed markets are closed, so their marks could improve off-hours measurement along layered exposures that link Bitcoin, crypto-treasury stocks, and…
Neural Estimation of Irreversibility in Real and Simulated Limit Order Book Paths
Hyeonjun Yeo, Doohwi Cha, Yoontae Hwang
A path indistinguishable from its own reverse carries no arrow of time, so time irreversibility is a necessary condition for a directed mechanism to be readable from trajectories a…
Entanglement Structure Across Phase Transitions in 1D Rydberg Atom Arrays
Hyeonjun Yeo, Kabgyun Jeong, Hyunchul Nha
Multipartite quantum entanglement plays a crucial role in the emergence of different quantum phases and their transitions in quantum many-body systems. It is of general interest to…
Rodeo Filtering for Direct Steady-State Estimation in Open Quantum Systems
Hyeonjun Yeo, Jongin Jeong, Soyoung Shin +1
Computing non-equilibrium steady states of open quantum systems is a challenging task on conventional computers, motivating quantum algorithms for direct steady-state estimation. A…
Designing Minimalistic Variational Quantum Ansatz Inspired by Algorithmic Cooling
Soyoung Shin, Ha Eum Kim, Hyeonjun Yeo +3
This study introduces a novel minimalistic variational quantum ansatz inspired by algorithmic cooling principles. The proposed Heat Exchange algorithmic cooling ansatz (HE ansatz)…
Reducing Circuit Depth in Quantum State Preparation for Quantum Simulation Using Measurements and Feedforward
Hyeonjun Yeo, Ha Eum Kim, IlKwon Sohn +1
Reducing circuit depth and identifying an optimal trade-off between circuit depth and width is crucial for successful quantum computation. In this context, midcircuit measurement a…
Approximating maximum independent set on Rydberg atom arrays using local detunings
Hyeonjun Yeo, Ha Eum Kim, Kabgyun Jeong
Rydberg atom arrays operated by a quantum adiabatic principle are among the most promising quantum simulating platforms due to their scalability and long coherence time. From the p…
Disentangling quantum neural networks for unified estimation of quantum entropies and distance measures
Myeongjin Shin, Seungwoo Lee, Junseo Lee +4
The estimation of quantum entropies and distance measures, such as von Neumann entropy, Rényi entropy, Tsallis entropy, trace distance, and fidelity-induced distances such as the B…
Weighted -Rényi Entropy Power Inequality: Information Theory to Quantum Shannon Theory
Junseo Lee, Hyeonjun Yeo, Kabgyun Jeong
We study the -Rényi entropy power inequality with a weight factor on two independent continuous random variables and . The extension essentially relies on a modulatio…
