ChartParser: Automatic Chart Parsing for Print-Impaired

no code implementations16 Nov 2022 Anukriti Kumar, Tanuja Ganu, Saikat Guha

Infographics are often an integral component of scientific documents for reporting qualitative or quantitative findings as they make it much simpler to comprehend the underlying complex information.

Document Navigability: A Need for Print-Impaired

no code implementations21 Jun 2022 Anukriti Kumar, Tanuja Ganu, Saikat Guha

Printed documents continue to be a challenge for blind, low-vision, and other print-disabled (BLV) individuals.

Broken News: Making Newspapers Accessible to Print-Impaired

no code implementations21 Jun 2022 Vishal Agarwal, Tanuja Ganu, Saikat Guha

Accessing daily news content still remains a big challenge for people with print-impairment including blind and low-vision due to opacity of printed content and hindrance from online sources.

Demonstration of quantum advantage by a joint detection receiver for optical communications using quantum belief propagation on a trapped-ion device

no code implementations25 Feb 2021 Conor Delaney, Kaushik P. Seshadreesan, Ian MacCormack, Alexey Galda, Saikat Guha, Prineha Narang

Demonstrations of quantum advantage have largely focused on computational speedups and on quantum simulation of many-body physics, limited by fidelity and capability of current devices.

Attaining quantum limited precision of localizing an object in passive imaging

no code implementations3 Feb 2021 Aqil Sajjad, Michael R Grace, Quntao Zhuang, Saikat Guha

We also find that the HG mode sorter, which is the optimal measurement for estimating the separation between point sources (or the length of a line object) is not only suboptimal, but it performs worse than direct imaging.

Entanglement-assisted capacity regions and protocol designs for quantum multiple-access channels

no code implementations28 Jan 2021 Haowei Shi, Min-Hsiu Hsieh, Saikat Guha, Zheshen Zhang, Quntao Zhuang

We solve the entanglement-assisted (EA) classical capacity region of quantum multiple-access channels with an arbitrary number of senders.

Belief Propagation with Quantum Messages for Quantum-Enhanced Classical Communications

1 code implementation9 Mar 2020 Narayanan Rengaswamy, Kaushik P. Seshadreesan, Saikat Guha, Henry D. Pfister

For space-based laser communications, when the mean photon number per received optical pulse is much smaller than one, there is a large gap between communications capacity achievable with a receiver that performs individual pulse-by-pulse detection, and the quantum-optimal "joint-detection receiver" that acts collectively on long codeword-blocks of modulated pulses; an effect often termed "superadditive capacity".

Optimal Measurements for Symmetric Quantum States with Applications to Optical Communication

1 code implementation16 Jul 2015 Hari Krovi, Saikat Guha, Zachary Dutton, Marcus P. da Silva

Even so, evaluating the actual probability of error (and other performance metrics) attained by the PGM on a GU set involves inverting large matrices, and is not easy in general.
