abstract
Advances in quantum information science (QIS) are providing transformative insights into the complexity of quantum many-body systems, potentially defining new frontiers in nuclear and high-energy physics. This review explores how QIS-derived techniques are fostering new analytic frameworks and algorithms - both classical and quantum - to tackle (some of the) present barriers to discovery in fundamental physics, with applicability to other science domains. We highlight how these techniques are shedding new light on the structure and dynamics of hadrons, nuclei, matter in extreme conditions, and beyond. Importantly, they are expected to play an essential role in the development of large-scale quantum simulations of such systems, particularly in setting the balance among quantum and classical computational resources.

Doped matchgate circuits achieve approximate parity-preserving 2-designs in polylogarithmic depth using a sparse number of non-Gaussian gates, with the design formation mapped exactly to a birth-death Markov chain.
Fermionic non-Gaussianity can be tested with O(n²/ϵ²) two-copy Bell shots or O(n³/ϵ⁴) single-copy shots and certified in noisy mixed states by a purity-corrected covariance witness.
Defines antiflatness of entanglement spectra, introduces antiflat majorization and FPOs for state convertibility, unifies measures via escort distributions and Bregman divergences, expresses Capacity of Entanglement as KL divergence derivative linked to QFI, and identifies maximal antiflatness on a
Subleading soft-gluon recoil rotates the heavy-quark spin-correlation plane; tracing over unresolved radiation dephases in-plane coherences while protecting the normal-axis correlation.
Tensor network simulations of two-flavor neutrinos link spectral splits to peaks in entanglement entropy and local minima in non-local magic, indicating resource redistribution drives the phenomenon.
In holographic Schwinger pair production, the excess capacity of entanglement is √λ(d−2)/(d−1)³ — positive for d>2, zero for d=2 — so the produced pair carries nonlocal magic for d>2.
