Relative-belief inference in quantum information theory

YS Teo, SU Shringarpure, H Jeong, N Prasannan… - Physical Review A, 2024 - APS
We introduce the framework of Bayesian relative belief that directly evaluates whether or not
the experimental data at hand support a given hypothesis regarding a quantum system by …

Evidence-based certification of quantum dimensions

YS Teo, SU Shringarpure, H Jeong, N Prasannan… - Physical review …, 2024 - APS
Identifying a reasonably small Hilbert space that completely describes an unknown quantum
state is crucial for efficient quantum information processing. We introduce a general …

Photonic Entanglement and Polarization Nonclassicality: Two Manifestations, One Nature

L Ares, N Prasannan, E Agudelo, A Luis… - arxiv preprint arxiv …, 2024 - arxiv.org
We demonstrate in theory and experiment the strict equivalence between nonclassical
polarization and the entanglement of indistinguishable photons, thereby unifying these two …

Low-noise balanced homodyne detection with superconducting nanowire single-photon detectors

M Protte, T Schapeler, J Sperling, TJ Bartley - Optica Quantum, 2024 - opg.optica.org
Superconducting nanowire single-photon detectors (SNSPDs) have been widely used to
study the discrete nature of quantum states of light in the form of photon-counting …
