Parallelized Givens Ansatz for Molecular ground-states: Bridging Accuracy and Efficiency on NISQ Platforms
M. R. Nirmal, Ankit Khandelwal, Manoj Nambiar +1
In recent years, the Variational Quantum Eigensolver (VQE) has emerged as one of the most popular algorithms for solving the electronic structure problem on near-term quantum compu…
Quantum Algorithms for tensor-SVD
Jezer Jojo, Ankit Khandelwal, M Girish Chandra
A promising area of applications for quantum computing is in linear algebra problems. In this work, we introduce two new quantum t-SVD (tensor-SVD) algorithms. The first algorithm…
Classification and transformations of quantum circuit decompositions for permutation operations
Ankit Khandelwal, Handy Kurniawan, Shraddha Aangiras +2
Efficient decomposition of permutation unitaries is vital as they frequently appear in quantum computing. In this paper, we identify the key properties that impact the decompositio…
Resource-Efficient Quantum Circuits for Molecular Simulations: A Case Study of Umbrella Inversion in Ammonia
M. R. Nirmal, Sharma S. R. K. C. Yamijala, Kalpak Ghosh +2
We conducted a thorough evaluation of various state-of-the-art strategies to prepare the ground state wavefunction of a system on a quantum computer, specifically within the framew…
On Modifying the Variational Quantum Singular Value Decomposition Algorithm
Jezer Jojo, Ankit Khandelwal, M Girish Chandra
In this work, we discuss two modifications that can be made to a known variational quantum singular value decomposition algorithm popular in the literature. The first is a change t…
Quantum Circuit Optimization through Iteratively Pre-Conditioned Gradient Descent
Dhruv Srinivasan, Kushal Chakrabarti, Nikhil Chopra +1
For typical quantum subroutines in the gate-based model of quantum computing, explicit decompositions of circuits in terms of single-qubit and two-qubit entangling gates may exist.…
