Paper Non-Gaussian Noise Magnetometry Using Local Spin Qubits Jonathan B. Curtis, Amir Yacoby, and Eugene Demler, Quantum 10, 2197 (2026). Atomic scale qubits, as may be realized in nitrogen vacancy (NV) centers in diamond, offer the opportunity to study magnetic field noise with nanometer scale spatial resolution. Using these…
Paper On the relation between perspective-neutral, algebraic, and effective quantum reference frames Julian De Vuyst, Philipp A. Hoehn, and Artur Tsobanjan, Quantum 10, 2196 (2026). The framework of internal quantum reference frames (QRFs) constitutes a universal toolset for dealing with symmetries in quantum theory and has led to new revelations in quantum gravity, gau…
Paper Simple logical quantum computation with concatenated symplectic double codes Noah Berthusen and Elijah Durso-Sabina, Quantum 10, 2195 (2026). There have been significant recent advances in constructing theoretical and practical quantum error correcting codes that function well as quantum memories; however, performing fault-toleran…
Paper Quantifying mixed-state entanglement via partial transpose and realignment moments Poetri Sonya Tarabunga and Tobias Haug, Quantum 10, 2194 (2026). Entanglement plays a crucial role in quantum information science and many-body physics, yet quantifying it in mixed quantum many-body systems has remained a notoriously difficult problem. He…
Paper Quantum phase estimation with optimal confidence interval using three control qubits Kaur Kristjuhan and Dominic W. Berry, Quantum 10, 2193 (2026). Quantum phase estimation is an important routine in many quantum algorithms, particularly for estimating the ground state energy in quantum chemistry simulations. This estimation involves ap…
Paper Measurement incompatibility in Bayesian multiparameter quantum estimation Francesco Albarelli, Dominic Branford, and Jesús Rubio, Quantum 10, 2192 (2026). We present a comprehensive and pedagogical formulation of Bayesian multiparameter quantum estimation. Within this framework, we analyse the role of measurement incompatibility and establish…
Paper Catalytic $z$-rotations in constant $T$-depth Isaac H. Kim, Quantum 10, 2191 (2026). We show that the $T$-depth of any single-qubit $z$-rotation can be reduced to $3$ if a certain catalyst state is available. To achieve an $\epsilon$-approximation, it suffices to have a catalyst sta…
Paper Robust topological quantum state transfer with long-range interactions in Rydberg arrays Siri Raupach, Beatriz Olmos, and Mathias B. M. Svendsen, Quantum 10, 2190 (2026). We develop a theoretical framework for fast, robust and high-fidelity topological quantum state transfer in one-dimensional systems with long-range couplings, motivated by chains of Rydberg…
Paper Efficient Graph State Generation in Linear Optics Seungbeom Chin and William John Munro, Quantum 10, 2189 (2026). Graph states are central resources for quantum information processing, supporting applications in computation, communication, and error correction. In photonic systems, they are typically as…
Paper Unconditional Quantum Advantage for Sampling with Shallow Circuits Adam Bene Watts and Natalie Parham, Quantum 10, 2188 (2026). Recent work by Bravyi, Gosset, and Koenig showed that there exists a search problem that a constant-depth quantum circuit can solve, but that any constant-depth classical circuit with bounde…
Paper Quantum Resource Comparison for Two Leading Surface Code Lattice Surgery Approaches Tyler LeBlond and Ryan S. Bennink, Quantum 10, 2187 (2026). Hamiltonian simulation is one of the most promising candidates for the demonstration of quantum advantage within the next ten years, and several studies have proposed end-to-end resource est…
Paper Disorder-Induced Entanglement Phase Transitions in Non-Hermitian Systems with Skin Effects Kai Li, Ze-Chuan Liu, and Yong Xu, Quantum 10, 2186 (2026). Non-Hermitian dynamics is ubiquitous in various physical systems. While recent study shows that such a dynamics leads to an area-law scaling of the entanglement entropy due to the non-Hermit…
Paper Promise of Graph Sparsification and Decomposition for Noise Reduction in QAOA: Analysis for Trapped-Ion Compilations Jai Moondra, Phillip C. Lotshaw, Greg Mohler, and Swati Gupta, Quantum 10, 2185 (2026). We develop new approximate compilation schemes that significantly reduce the expense of compiling the Quantum Approximate Optimization Algorithm (QAOA) for solving the Max-Cut problem. Our m…
Paper Detection of a Rényi Index Dependent Transition in Entanglement Entropy Scaling Hatem Barghathi and Adrian Del Maestro, Quantum 10, 2184 (2026). The scaling of entanglement with subsystem size encodes key information about phases and criticality, but the von Neumann entropy is costly to access in experiments and simulations, often re…
Perspective Charting separability and entanglement of diagonal Dicke states Guillem Müller-Rigat, Quantum Views 10, 87 (2026). Dicke states are multipartite quantum states first introduced in [1] to describe the collective excitations of $N$ two-level atoms coupled to a single-mode electromagnetic field. They span a s…
Paper Entanglement growth in the dark intervals of a locally monitored free-fermion chain Giovanni Di Fresco, Youenn Le Gal, Davide Valenti, Marco Schiró, and Angelo Carollo, Quantum 10, 2183 (2026). We consider a free fermionic chain with monitoring of the particle density on a single site of the chain and study the entanglement dynamics of quantum jump trajectories. We show that the en…
