Driver State and Behavior Detection Through Smart Wearables
Arash Tavakoli, Shashwat Kumar, Mehdi Boukhechba +1
Integrating driver, in-cabin, and outside environment's contextual cues into the vehicle's decision making is the centerpiece of semi-automated vehicle safety. Multiple systems hav…
Quantum-Classical Separation in Bounded-Resource Tasks Arising from Measurement Contextuality
Shashwat Kumar, Eliott Rosenberg, Alejandro Grajales Dau +280
The prevailing view is that quantum phenomena can be harnessed to tackle certain problems beyond the reach of classical approaches. Quantifying this capability as a quantum-classic…
Protomon: A Multimode Qubit in the Fluxonium Molecule
Shashwat Kumar, Xinyuan You, Xanthe Croot +7
Qubits that are intrinsically insensitive to depolarization and dephasing errors promise to significantly reduce the overhead of fault-tolerant quantum computing. At their optimal…
A Shape-Based Functional Index for Objective Assessment of Pediatric Motor Function
Shashwat Kumar, Arafat Rahman, Robert Gutierrez +6
Clinical assessments for neuromuscular disorders, such as Spinal Muscular Atrophy (SMA) and Duchenne Muscular Dystrophy (DMD), continue to rely on subjective measures to monitor tr…
Fair Distribution of Digital Payments: Balancing Transaction Flows for Regulatory Compliance
Ashlesha Hota, Shashwat Kumar, Daman Deep Singh +3
The concentration of digital payment transactions in just two UPI apps like PhonePe and Google Pay has raised concerns of duopoly in India s digital financial ecosystem. To address…
Hilbert space signatures of non-ergodic glassy dynamics
Aleksey Lunkin, Nicole S. Ticea, Shashwat Kumar +292
Disorder in quantum many-body systems can drive transitions between ergodic and non-ergodic phases, yet the nature--and even the existence--of these transitions remains intensely d…
An Elastic Shape Variational Autoencoder for Skeleton Pose Trajectories
Arafat Rahman, Shashwat Kumar, Laura E. Barnes +1
Deep generative models provide flexible frameworks for modeling complex, structured data such as images, videos, 3D objects, and texts. However, when applied to sequences of human…
Bayesian In Vivo Tracking of Synapses using Joint Poisson Deconvolution and Diffeomorphic Registration
Shashwat Kumar, Dominic M. Padova, Binish Narang +6
Synapses are densely packed submicron structures that dynamically reorganize during learning and memory formation. Longitudinal \textit{in vivo} imaging of fluorescently tagged syn…
Dynamical nuclear polarization for dissipation-induced entanglement in NV centers
Shishir Khandelwal, Shashwat Kumar, Nicolas Palazzo +2
We propose a practical implementation of a two-qubit entanglement engine which denotes a scheme to generate quantum correlations through purely dissipative processes. On a diamond…
Shape Analysis for Pediatric Upper Body Motor Function Assessment
Shashwat Kumar, Robert Gutierez, Debajyoti Datta +5
Neuromuscular disorders, such as Spinal Muscular Atrophy (SMA) and Duchenne Muscular Dystrophy (DMD), cause progressive muscular degeneration and loss of motor function for 1 in 6,…
2D transmons with lifetimes and coherence times exceeding 1 millisecond
Matthew P. Bland, Faranak Bahrami, Jeronimo G. C. Martinez +14
Materials improvements are a powerful approach to reducing loss and decoherence in superconducting qubits because such improvements can be readily translated to large scale process…
Observation of disorder-induced superfluidity
Nicole Ticea, Elias Portoles, Eliott Rosenberg +298
The emergence of states with long-range correlations in a disordered landscape is rare, as disorder typically suppresses the particle mobility required for long-range coherence. Bu…
Geometry matters: Exploring language examples at the decision boundary
Debajyoti Datta, Shashwat Kumar, Laura Barnes +1
A growing body of recent evidence has highlighted the limitations of natural language processing (NLP) datasets and classifiers. These include the presence of annotation artifacts…
Smooth Reparameterizations of Functions on Simplicial Product Spaces: Applications to Probabilistic Tensor Decomposition and Functional Data Registration
Shashwat Kumar, Arafat Rahman, Anuj Srivastava +1
We consider optimization problems defined on product spaces of simplices. Examples of this class of problems include learning low-rank discrete multivariate probability distributio…
Observation of disorder-free localization using a (2+1)D lattice gauge theory on a quantum processor
Gaurav Gyawali, Shashwat Kumar, Yuri D. Lensky +219
Disorder-induced phenomena in quantum many-body systems pose significant challenges for analytical methods and numerical simulations at relevant time and system scales. To reduce t…
