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 communication over discrete memoryless interference channels or multiple access channels without feedback, where transmitters exploit classical, quantum, or no-signalin…
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…
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…
Analog-Digital Beam Focusing for Line of Sight Wide-Aperture MIMO with Spherical Wavefronts
Jiyoung Yun, Hojun Rho, Wan Choi
Enhancing high-speed wireless communication in the future relies significantly on harnessing high frequency bands effectively. These bands predominantly operate in line-of-sight (L…
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…
