Quantum resource redistribution drives spectral splits in dense neutrino gases
Michael Hite, Pooja Siwach
Whether a quantum many-body system can be efficiently simulated hinges not only on its size but also on how quantum resources are organized within it. We characterize the quantum r…
Advancing quantum simulations of nuclear shell model with noise-resilient protocols
Nifeeya Singh, Pooja Siwach, P. Arumugam
Some of the computational limitations in solving the nuclear many-body problem could be overcome by utilizing quantum computers. The nuclear shell-model calculations providing deep…
Quantum simulations of nuclear resonances with variational methods
Ashutosh Singh, Pooja Siwach, P. Arumugam
The many-body nature of nuclear physics problems poses significant computational challenges. These challenges become even more pronounced when studying the resonance states of nucl…
Collective neutrino oscillations on a quantum computer with hybrid quantum-classical algorithm
Pooja Siwach, Kaytlin Harrison, A. Baha Balantekin
We simulate the time evolution of collective neutrino oscillations in two-flavor settings on a quantum computer. We explore the generalization of Trotter-Suzuki approximation to ti…
A Quantum Algorithm for the Linear Response of Nuclei
Abhishek, Nifeeya Singh, Pooja Siwach +1
We present a quantum algorithm to obtain the response of the atomic nucleus to a small external electromagnetic perturbation. The Hamiltonian of the system is presented by a harmon…
Symmetry breaking/symmetry preserving circuits and symmetry restoration on quantum computers: A quantum many-body perspective
Denis Lacroix, Edgar Andres Ruiz Guzman, Pooja Siwach
We discuss here some aspects related to the symmetries of a quantum many-body problem when trying to treat it on a quantum computer. Several features related to symmetry conservati…
Quantum computation of nuclear observables involving linear combination of unitary operators
Pooja Siwach, P. Arumugam
We present the quantum computation of nuclear observables where the operators of interest are first decomposed in terms of the linear combination of unitaries. Then we utilise the…
Filtering states with total spin on a quantum computer
Pooja Siwach, Denis Lacroix
Starting from a general wave function described on a set of spins/qubits, we propose several quantum algorithms to extract the components of this state on eigenstates of the total…
