Hamiltonian learning from time dynamics using variational algorithms
Rishabh Gupta, Raja Selvarajan, Manas Sajjan +2
The Hamiltonian of a quantum system governs the dynamics of the system via the Schrodinger equation. In this paper, the Hamiltonian is reconstructed in the Pauli basis using measur…
Dimensionality reduction with variational encoders based on subsystem purification
Raja Selvarajan, Manas Sajjan, Travis S. Humble +1
Efficient methods for encoding and compression are likely to pave way towards the problem of efficient trainability on higher dimensional Hilbert spaces overcoming issues of barren…
Magnetic Phases of Spatially-Modulated Spin-1 Chains in Rydberg Excitons: Classical and Quantum Simulations
Manas Sajjan, Hadiseh Alaeian, Sabre Kais
In this work, we study the magnetic phases of a spatially-modulated chain of spin-1 Rydberg excitons. Using the Density Matrix Renormalization Group (DMRG) technique we study vario…
Imaginary components of out-of-time correlators and information scrambling for navigating the learning landscape of a quantum machine learning model
Manas Sajjan, Vinit Singh, Raja Selvarajan +1
We introduce and analytically illustrate that hitherto unexplored imaginary components of out-of-time correlators can provide unprecedented insight into the information scrambling…
Variational Approach to Quantum State Tomography based on Maximal Entropy Formalism
Rishabh Gupta, Manas Sajjan, Raphael D. Levine +1
Quantum state tomography is an integral part of quantum computation and offers the starting point for the validation of various quantum devices. One of the central tasks in the fie…
