Fault-tolerant quantum algorithms for simulating atomic nuclei
James Benstead, Michael Garn, Neil Gaspar +5
To maximize the value of fault-tolerant quantum computers, it is essential to develop concrete applications beyond well-established domains such as chemistry and condensed-matter p…
Qubit-efficient variational algorithm for nuclear structure
Chandan Sarma, Paul Stevenson
In this work, we compare three qubit-mapping strategies to study the structure of the nuclear ground state within the shell model description employing the Variational Quantum Eige…
Low -count preparation of nuclear eigenstates with tensor networks
Joe Gibbs, Lukasz Cincio, Chandan Sarma +2
We present an efficient protocol leveraging classical computation to support Initial State Preparation for strongly correlated fermionic systems, a critical bottleneck for fault-to…
A low-circuit-depth quantum computing approach to the nuclear shell model
Chandan Sarma, Paul Stevenson
In this work, we introduce a new qubit mapping strategy for the Variational Quantum Eigensolver (VQE) applied to nuclear shell model calculations, where each Slater determinant (SD…
Ab initio no-core shell-model study of Na isotopes
Chandan Sarma, Praveen C. Srivastava
We have done a systematic no-core shell-model study of Na isotopes. The low-energy spectra of these sodium isotopes consisting of natural and un-natural parity states wer…
Mirror and triplet energy differences in -shell nuclei using microscopic interactions with isospin-symmetry breaking effects
Chandan Sarma, Praveen C. Srivastava, Toshio Suzuki +1
In this study, we developed and tested two different isospin symmetry-breaking (ISB) versions of the microscopic DJ16A interaction. Starting with the isospin symmetric DJ16A intera…
