Conditional disclosure of secrets with quantum resources
Vahid R. Asadi, Kohdai Kuroiwa, Debbie Leung +3
The conditional disclosure of secrets (CDS) primitive is among the simplest cryptographic settings in which to study the relationship between communication, randomness, and securit…
Generalized Quantum Stein's Lemma: Redeeming Second Law of Resource Theories
Hayata Yamasaki, Kohdai Kuroiwa
[Note: After the first version of this manuscript was uploaded, the authors of [Berta, Brandão, Gour, Lami, Plenio, Regula, and Tomamichel, Quantum 7, 1103 (2023)] pointed out an i…
Entanglement cost for infinite-dimensional physical systems
Hayata Yamasaki, Kohdai Kuroiwa, Patrick Hayden +1
We prove that the entanglement cost equals the regularized entanglement of formation for any infinite-dimensional quantum state with finite quantum entropy on at least one…
Robustness- and weight-based resource measures without convexity restriction: Multicopy witness and operational advantage in static and dynamical quantum resource theories
Kohdai Kuroiwa, Ryuji Takagi, Gerardo Adesso +1
Quantum resource theories (QRTs) provide a unified framework to analyze quantum properties as resources for achieving advantages in quantum information processing. The generalized…
Every quantum helps: Operational advantage of quantum resources beyond convexity
Kohdai Kuroiwa, Ryuji Takagi, Gerardo Adesso +1
Identifying what quantum-mechanical properties are useful to untap a superior performance in quantum technologies is a pivotal question. Quantum resource theories provide a unified…
Effect of non-unital noise on random circuit sampling
Bill Fefferman, Soumik Ghosh, Michael Gullans +2
In this work, drawing inspiration from the type of noise present in real hardware, we study the output distribution of random quantum circuits under practical non-unital noise sour…
