Protocol for Purifying Noisy Preparation and Measurements of Qubits

Jaemin Kim, Seungchan Seo, Jiyoung Yun +2

Noise affecting qubit preparation and measurements accounts for a significant fraction of errors in quantum information processing. This is especially critical in tasks like variat…

Structured Masked Diffusion for Joint Multiuser Decoding

Taekyun Lee, Jiyoung Yun, Jeffrey G. Andrews +1

In joint multiuser decoding, a receiver recovers a set of messages from a single noisy aggregate of many simultaneous transmissions. Classical decoders rely on rule-based mechanism…

Enhancing Sum Capacity via Quantum and No-Signaling Cooperation Between Transmitters

Seung-Hyun Nam, Hyun-Young Park, Jiyoung Yun +3

We consider a communication scenario over a discrete memoryless interference channel or multiple access channel without feedback, where transmitters exploit classical, quantum, or…

Purification of Noisy Measurements and Faithful Distillation of Entanglement

Jaemin Kim, Jiyoung Yun, Joonwoo Bae

We consider entanglement distillation with noisy operations in which quantum measurements that constitute a general quantum operation are particularly noisy. We present a protocol…

Static Quantum Errors and Purification

Jaemin Kim, Seungchan Seo, Jiyoung Yun +1

State preparation that initializes quantum systems in a fiducial state and measurements to read outcomes after the evolution of quantum states, both essential elements in quantum i…
