Quantum 9, 1810 (2025). https://doi.org/10.22331/q-2025-07-23-1810 Bosonic codes encode quantum information into a single infinite-dimensional physical system endowed with error correction capabilities. This reduces the need for complex management of many physical constituents compared with standard […]
Quantum 9, 1809 (2025). https://doi.org/10.22331/q-2025-07-23-1809 We provide a graphical method to describe and analyze non-Gaussian quantum states using a hypergraph framework. These states are pivotal resources for quantum computing, communication, and metrology, but their characterization […]
Quantum 9, 1808 (2025). https://doi.org/10.22331/q-2025-07-22-1808 Discrete models of holographic dualities, typically modeled by tensor networks on hyperbolic tilings, produce quantum states with a characteristic quasiperiodic disorder not present in continuum holography. In this work, we […]
Quantum 9, 1807 (2025). https://doi.org/10.22331/q-2025-07-22-1807 Certifying quantum properties from the probability distributions they induce is an important task for several purposes. While this framework has been largely explored and used for quantum states, its extrapolation […]
Quantum 9, 1806 (2025). https://doi.org/10.22331/q-2025-07-22-1806 Quantum state estimation is a fundamental task in quantum information theory, where one estimates real parameters continuously embedded in a family of quantum states. In the theory of quantum state […]

Quantum 9, 1804 (2025). https://doi.org/10.22331/q-2025-07-22-1804 Autonomous quantum memories are a way to passively protect quantum information using engineered dissipation that creates an “always-on” decoder. We analyze Markovian autonomous decoders that can be implemented with a […]
Quantum 9, 1803 (2025). https://doi.org/10.22331/q-2025-07-22-1803 We investigate the challenge of classical simulation of unitary quantum dynamics with variational Monte Carlo approaches, addressing the instabilities and high computational demands of existing methods. By systematically analyzing the […]
Quantum 9, 1802 (2025). https://doi.org/10.22331/q-2025-07-22-1802 Non-Abelian gauge theories underlie our understanding of fundamental forces of modern physics. Simulating them on quantum hardware is an outstanding challenge in the rapidly evolving field of quantum simulation. A […]
Quantum 9, 1801 (2025). https://doi.org/10.22331/q-2025-07-21-1801 Nonstabilizerness or `magic’ is a key resource for quantum computing and a necessary condition for quantum advantage. Non-Clifford operations turn stabilizer states into resourceful states, where the amount of nonstabilizerness […]
