Eigenstate-Selective Entangled Two-Photon Absorption in Monolayer WSe

Minseok A. Jang, Hongki Yoo

We show that the Bell-state phase of a polarization-entangled photon pair controls the biexciton eigenstate distribution produced by entangled two-photon absorption in monolayer WS…

Entanglement-swapping measurements for deterministic entanglement distribution

Mir Alimuddin, Jaemin Kim, Antonio Acín +1

Entanglement swapping is a key primitive for distributing entanglement over quantum networks, but different measurement outcomes can produce end-to-end states with different entang…

Sharing quantum indistinguishability with multiple parties

Lemieux Wang, Hanwool Lee, Joonwoo Bae +1

Quantum indistinguishability of non-orthogonal quantum states is a valuable resource in quantum information applications such as cryptography and randomness generation. In this art…

Practical and Efficient Verification of Entanglement with Incomplete Measurement Settings

Jiheon Seong, Jin-Woo Kim, Seungchan Seo +6

In this work, we present a practical and efficient framework for verifying entangled states when only a tomographically incomplete measurement setting is available-specifically, wh…

Autonomously Designed Pulses for Precise, Site-Selective Control of Atomic Qubits

Sanghyo Park, Seuk Lee, Keunyoung Lee +2

Quantum computers based on cold-atom arrays offer long-lived qubits with programmable connectivity, yet their progress toward fault-tolerant operation is limited by the relatively…

Fault-Tolerant Encoding of Logical Qudits in Spin Systems

Sumin Lim

Universal quantum computers require fault-tolerant logical qudits, as qudits naturally align with the simulation of multi-level physical systems. Here, we present a general framewo…
