Blind-spots of Randomized Benchmarking Under Temporal Correlations
Varun Srivastava, Abhinash Kumar Roy, Soumik Mahanti +3
Randomized benchmarking (RB) is a widely adopted protocol for estimating the average gate fidelity in quantum hardware. However, its standard formulation relies on the assumption o…
Practical Tomography of Multi-Time Processes
Abhinash Kumar Roy, Varun Srivastava, Christina Giarmatzi +1
Characterising multi-time quantum processes is essential for analysing temporally correlated noise and for designing effective control and mitigation strategies. A complete operati…
Hamiltonian characterisation of multi-time processes with classical memory
Kaumudibikash Goswami, Abhinash Kumar Roy, Varun Srivastava +4
A central problem in open quantum systems is the characterization of non-Markovian processes, where an environment retains the memory of its interaction with the system. A key dist…
MapIQ: Evaluating Multimodal Large Language Models for Map Question Answering
Varun Srivastava, Fan Lei, Srija Mukhopadhyay +2
Recent advancements in multimodal large language models (MLLMs) have driven researchers to explore how well these models read data visualizations, e.g., bar charts, scatter plots.…
