Quantum 10, 2184 (2026). https://doi.org/10.22331/q-2026-08-07-2184 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 requiring full […]
Quantum 10, 2183 (2026). https://doi.org/10.22331/q-2026-08-03-2183 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 […]
Quantum 10, 2182 (2026). https://doi.org/10.22331/q-2026-08-03-2182 The simulation of large-scale classical systems in exponentially small space on quantum computers has gained attention. The prior work demonstrated that a quantum algorithm offers an exponential speedup over any […]
Quantum 10, 2181 (2026). https://doi.org/10.22331/q-2026-07-31-2181 We construct several families of entanglement-assisted quasi-cyclic quantum LDPC (EA-QC-QLDPC) codes via structured tilings of permutation matrices. The entanglement-unassisted portion of the joint Tanner graph of the proposed EA-QC-QLDPC code […]
Quantum 10, 2180 (2026). https://doi.org/10.22331/q-2026-07-30-2180 In recent work [Phys. Rev. X 16, 021050], we proposed a unified notion of nonclassicality that applies to arbitrary processes in quantum theory, including individual quantum states, measurements, and sets […]
Quantum 10, 2179 (2026). https://doi.org/10.22331/q-2026-07-29-2179 In 2024, Kliuchnikov and Schönnenbeck showed a connection between the Barnes Wall lattices, stabilizer states and Clifford operations. In this work, we study their results and relate them to the […]
Quantum 10, 2178 (2026). https://doi.org/10.22331/q-2026-07-29-2178 Efficient operation of quantum batteries requires not only fast energy transfer but also the ability to halt the charging process to prevent reverse flow. Existing approaches typically rely on direct […]
Quantum 10, 2177 (2026). https://doi.org/10.22331/q-2026-07-29-2177 The task of atom rearrangement has emerged in the last decade as a fundamental building block in the development of neutral atom-based quantum processors. As such processors grow to thousands […]
Quantum 10, 2176 (2026). https://doi.org/10.22331/q-2026-07-29-2176 Dynamical stabilizer codes may offer a practical route to large-scale quantum computation. Such codes are defined by a schedule of error-detecting measurements, which allows for flexibility in their construction. In […]
Quantum 10, 2175 (2026). https://doi.org/10.22331/q-2026-07-28-2175 Based on the mapping between stabilizer quantum error correcting codes and disordered statistical mechanics models, we define a ratio of partition functions that measures the success probability for maximum partition […]
