Quantum Resources in Non-Abelian Lattice Gauge Theories: Nonstabilizerness, Multipartite Entanglement, and Fermionic Non-Gaussianity
Gopal Chandra Santra, Julius Mildenberger, Edoardo Ballini +3
Lattice gauge theories (LGTs) represent one of the most ambitious goals of quantum simulation. From a practical implementation perspective, non-Abelian theories present significant…
Role of Nonstabilizerness in Quantum Optimization
Chiara Capecci, Gopal Chandra Santra, Alberto Bottarelli +2
Quantum optimization has emerged as a promising approach for tackling complicated classical optimization problems using quantum devices. However, the extent to which such algorithm…
Complexity transitions in chaotic quantum systems: Nonstabilizerness, entanglement, and fractal dimension in SYK and random matrix models
Gopal Chandra Santra, Alex Windey, Soumik Bandyopadhyay +2
Complex quantum systems -- composed of many, interacting particles -- are intrinsically difficult to model. When a quantum many-body system is subject to disorder, it can undergo t…
Disorder-averaged Qudit Dynamics
Gopal Chandra Santra, Philipp Hauke
Understanding how physical systems are influenced by disorder is a fundamental challenge in quantum science. Addressing its effects often involves numerical averaging over a large…
Genuine Multipartite Entanglement in Quantum Optimization
Gopal Chandra Santra, Sudipto Singha Roy, Daniel J. Egger +1
The ability to generate bipartite entanglement in quantum computing technologies is widely regarded as pivotal. However, the role of genuinely multipartite entanglement is much les…
Commensurate supersolids and re-entrant transitions in an extended Bose-Hubbard ladder
Ashwath N Madhusudan, Gopal Chandra Santra, Inderpreet Kaur +2
We investigate the ground state phases of an extended Bose-Hubbard ladder of unit filling via the density-matrix-renormalization-group method and, in particular, the effect of rung…
Squeezing and quantum approximate optimization
Gopal Chandra Santra, Fred Jendrzejewski, Philipp Hauke +1
Variational quantum algorithms offer fascinating prospects for the solution of combinatorial optimization problems using digital quantum computers. However, the achievable performa…
