Towards a Hybrid Quantum Enhanced Solution for Densest k-Subgraph Problem
Ravi Sangwan, Prabhat Anand, M Girish Chandra
We study the application of Gaussian Boson Sampling (GBS) to the densest k-subgraph problem (DkSP). GBS with hard post-selection suffers from poor sampling efficiency due to strict…
In-Substrate Imaging of Diamond hBN FET Current via Widefield Quantum Diamond Microscopy
Anuj Bathla, Subrat Kumar Pradhan, Ajit Kumar Dash +7
We demonstrate widefield magnetic imaging of current flow in hydrogen terminated diamond field effect transistors (FETs) through in-substrate nitrogen vacancy (NV) centers. Hydroge…
QDsiM: A Noise-Aware Simulation Toolkit for Quantum Diamond Microscope
Satyam Pandey, Abhimanyu Magapu, Prabhat Anand +2
The nitrogen-vacancy (NV) center in diamond is a leading solid-state platform for room-temperature quantum magnetometry owing to its long spin coherence times, optical spin initial…
Phase-Based Approaches for Rapid Construction of Magnetic Fields in NV Magnetometry
Prabhat Anand, Ankit Khandelwal, Achanna Anil Kumar +5
With the second quantum revolution underway, quantum-enhanced sensors are moving from laboratory demonstrations to field deployments, providing enhanced and even new capabilities.…
