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…

Deutsch-Jozsa and Bernstein-Vazirani algorithm using single-particle discrete-time quantum walk
Ravi Sangwan, Vikas Ramaswamy, Henry Sukumar +1
The paper introduces an efficient implementation of the Deutsch-Jozsa and Bernstein-Vazirani algorithm using the single-particle discrete-time quantum walk. We also provide a detai…
