Advancing Practical Quantum Embedding Simulations via Operator Commutativity Based State Preparation for Complex Chemical Systems
Dibyendu Mondal, Ashish Kumar Patra, Rahul Maitra
Determining the exponentially scaled ground state wavefunction and the associated molecular properties remains one of the central challenges in quantum chemistry. Hybrid quantum-cl…
Fractional Revival Dynamics in Kerr-Type Systems: Angular Momentum Moments and Classical Analogs
Ashish Kumar Patra, Saikumar Krithivasan
Wave packet revivals and fractional revivals are hallmark quantum interference phenomena that arise in systems with nonlinear energy spectra, and their signatures in expectation va…
A Polylogarithmic-Time Quantum Algorithm for the Laplace Transform
Akash Kumar Singh, Ashish Kumar Patra, Anurag K. S. V. +3
We introduce a quantum algorithm to perform the Laplace transform on quantum computers. Already, the quantum Fourier transform (QFT) is the cornerstone of many quantum algorithms,…
Resource Estimation for VQE on Small Molecules: Impact of Fermion Mappings and Hamiltonian Reductions
Anurag K. S. V., Ashish Kumar Patra, Vikas Dattatraya Ghevade +5
Accurate determination of ground-state energies for molecules remains a challenge in quantum chemistry and a cornerstone for progress in fields such as drug discovery and materials…
