Parameter-free Adaptive Sparse Attention via Compression-Based Content Selection
Debarshi Kundu, Swaroop Ghosh, Vasant Honavar
Data-adaptive sparse attention masks substantially outperform fixed patterns (e.g., BigBird and Longformer) and can even exceed dense attention on long sequences. Existing adaptive…
Projection-Free Transformers via Gaussian Kernel Attention
Debarshi Kundu, Archisman Ghosh, Swaroop Ghosh +1
Self-attention in Transformers is typically implemented as , where , , and are learned linear projections of the input…
No Tile Left Behind: Multiprogramming for Surface-Code Architectures
Archisman Ghosh, Avimita Chatterjee, Swaroop Ghosh
Fault-tolerant quantum computing (FTQC) is emerging as the architectural regime in which practical large-scale quantum workloads will execute. In this setting, however, multiprogra…
Toward designing workload-aware Surface Code Architectures
Archisman Ghosh, Avimita Chatterjee, Swaroop Ghosh
Practical quantum advantage is expected to depend on fault-tolerant quantum computing, although the architectural overhead needed to support fault tolerance is still extremely high…
Design Automation in Quantum Error Correction
Archisman Ghosh, Avimita Chatterjee, Swaroop Ghosh
Quantum error correction (QEC) underpins practical fault-tolerant quantum computing (FTQC) by addressing the fragility of quantum states and mitigating decoherence-induced errors.…
Survival of the Optimized: An Evolutionary Approach to T-depth Reduction
Archisman Ghosh, Avimita Chatterjee, Swaroop Ghosh
Quantum Error Correction (QEC) is the cornerstone of practical Fault-Tolerant Quantum Computing (FTQC), but incurs enormous resource overheads. Circuits must decompose into Cliffor…
