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 […]
Quantum 9, 1800 (2025). https://doi.org/10.22331/q-2025-07-21-1800 Fault-tolerant quantum computation (FTQC) is essential to implement quantum algorithms in a noise-resilient way, and thus to enjoy advantages of quantum computers even with presence of noise. In FTQC, a […]
Quantum 9, 1799 (2025). https://doi.org/10.22331/q-2025-07-21-1799 Quantum computers are expected to enable fast solving of large-scale combinatorial optimization problems. However, their limitations in fidelity and the number of qubits prevent them from handling real-world problems. Recently, […]
