Nonstabilizerness versus entanglement in matrix product states

M Frau, PS Tarabunga, M Collura, M Dalmonte… - Physical Review B, 2024 - APS
In this paper, we investigate the relationship between entanglement and nonstabilizerness
(also known as magic) in matrix product states (MPSs). We study the relation between magic …

Stabilizer entropies are monotones for magic-state resource theory

L Leone, L Bittel - arXiv preprint arXiv:2404.11652, 2024 - arxiv.org
We establish the monotonicity of stabilizer entropies for $\alpha\geq 2$ within the context of
magic-state resource theory restricted to pure states. Additionally, we show that linear …

Non-stabilizerness in U (1) lattice gauge theory

PRN Falcão, PS Tarabunga, M Frau, E Tirrito… - arXiv preprint arXiv …, 2024 - arxiv.org
We present a thorough investigation of non-stabilizerness-a fundamental quantum resource
that quantifies state complexity within the framework of quantum computing-in a one …

Exact solution of long-range stabilizer R\'enyi entropy in the dual-unitary XXZ model

JAM López, P Kos - arXiv preprint arXiv:2405.04448, 2024 - arxiv.org
Quantum systems can not be efficiently simulated classically due to the presence of
entanglement and nonstabilizerness, also known as quantum magic. Here we study the …

Quantum State Designs with Clifford Enhanced Matrix Product States

G Lami, T Haug, J De Nardis - arXiv preprint arXiv:2404.18751, 2024 - arxiv.org
Nonstabilizerness, ormagic', is a critical quantum resource that, together with entanglement,
characterizes the non-classical complexity of quantum states. Here, we address the problem …

Chaos and magic in the dissipative quantum kicked top

G Passarelli, P Lucignano, D Rossini… - arXiv preprint arXiv …, 2024 - arxiv.org
We consider an infinite-range interacting quantum spin-1/2 model, undergoing periodic
kicking and dissipatively coupled with an environment. In the thermodynamic limit, it is …
