Area Theorems for Quantum Error Correction
Avijit Mandal, Mert Gökduman, Henry D. Pfister
The extrinsic information transfer (EXIT) and generalized EXIT (GEXIT) area theorems provide fundamental conservation laws that connect the rate of classical codes to the performan…
Efficient capacity-achieving entanglement generation with application to pure-loss Bosonic channels
Avijit Mandal, Christophe Piveteau, Henry D. Pfister +1
While the ultimate limits on the rate of quantum communication over noisy channels are well-established, very few efficient coding schemes achieving these limits are known. This co…
Quantum Message Passing Convergence and Vanishing Block-Error Probability for Random LDPC Codes
Avijit Mandal, Christophe Piveteau, Joseph M. Renes +1
Belief propagation with quantum messages (BPQM) is a quantum algorithm that decodes classical codes transmitted over classical--quantum channels. It realizes optimal decoding on tr…
Enhanced Feedback Mechanisms for Resource-Efficient Incremental Redundancy
Mustafa Cemil Coşkun, Ahmed Elkelesh, Avijit Mandal +1
Incremental redundancy (IR) can reduce error rates by spreading coded bits across multiple transmission attempts. However, conventional stop-and-wait operation with coarse feedback…
Affine Filtering Measurements and Their Applications to Quantum Decoding
Avijit Mandal, Noah Shutty, Henry D. Pfister +1
Unambiguous state discrimination (USD) measurements are attractive because outcomes are either marked as conclusive (i.e., error free) or inconclusive (i.e., erased). We study affi…
Quantum Message Passing for Factor Graphs over Finite Abelian Groups
Avijit Mandal, Henry D. Pfister
We develop a quantum message-passing framework for factor graphs over finite abelian groups. Our starting point is the task of discriminating between a collection of quantum states…
Optimization Using Locally-Quantum Decoders
Noah Shutty, Avijit Mandal, Seyoon Ragavan +8
It was pointed out in [JSW+25] that widely-studied optimization problems such as D-regular max-k-XORSAT can be reduced to decoding of LDPC codes, using quantum algorithms related t…
Belief Propagation with Quantum Messages for Symmetric Q-ary Pure-State Channels
Avijit Mandal, Henry D. Pfister
Belief propagation with quantum messages (BPQM) provides a low-complexity alternative to collective measurements for communication over classical--quantum channels. Prior BPQM cons…
Reed-Muller Codes on CQ Channels via a New Correlation Bound for Quantum Observables
Avijit Mandal, Henry D. Pfister
The question of whether Reed--Muller (RM) codes achieve capacity on binary memoryless symmetric (BMS) channels has drawn attention since it was resolved positively for the binary e…
Quantum State Compression with Polar Codes
Jack Weinberg, Avijit Mandal, Henry D. Pfister
In the quantum compression scheme proposed by Schumacher, Alice compresses a message that Bob decompresses. In that approach, there is some probability of failure and, even when su…
Polar Codes for CQ Channels: Decoding via Belief-Propagation with Quantum Messages
Avijit Mandal, S. Brandsen, Henry D. Pfister
This paper considers the design and decoding of polar codes for general classical-quantum (CQ) channels. It focuses on decoding via belief-propagation with quantum messages (BPQM)…
ExpresSense: Exploring a Standalone Smartphone to Sense Engagement of Users from Facial Expressions Using Acoustic Sensing
Pragma Kar, Shyamvanshikumar Singh, Avijit Mandal +2
Facial expressions have been considered a metric reflecting a person's engagement with a task. While the evolution of expression detection methods is consequential, the foundation…
mmDrive: mmWave Sensing for Live Monitoring and On-Device Inference of Dangerous Driving
Argha Sen, Avijit Mandal, Prasenjit Karmakar +2
Detecting dangerous driving has been of critical interest for the past few years. However, a practical yet minimally intrusive solution remains challenging as existing technologies…
Towards Maximizing Nonlinear Delay Sensitive Rewards in Queuing Systems
Sushmitha Shree S, Avijit Mandal, Avhishek Chatterjee +1
We consider maximizing the long-term average reward in a single server queue, where the reward obtained for a job is a non-increasing function of its sojourn time. The motivation b…
Belief Propagation with Quantum Messages for Symmetric Classical-Quantum Channels
S. Brandsen, Avijit Mandal, Henry D. Pfister
Belief propagation (BP) is a classical algorithm that approximates the marginal distribution associated with a factor graph by passing messages between adjacent nodes in the graph.…
Optimizing Age-of-Information in Adversarial Environments with Channel State Information
Avijit Mandal, Rajarshi Bhattacharjee, Abhishek Sinha
This paper considers a multi-user downlink scheduling problem with access to the channel state information at the transmitter (CSIT) to minimize the Age-of-Information (AoI) in a n…
