Quantum 9, 1744 (2025). https://doi.org/10.22331/q-2025-05-15-1744 Losses are one of the main bottlenecks for the distribution of entanglement in quantum networks, which can be overcome by the implementation of quantum repeaters. The most basic form of […]
Quantum 9, 1743 (2025). https://doi.org/10.22331/q-2025-05-15-1743 Quantum detailed balance is formulated in terms of elementary transitions, in close analogy to detailed balance in a classical Markov chain on a finite set of points. An elementary transition […]
Quantum 9, 1742 (2025). https://doi.org/10.22331/q-2025-05-13-1742 Time evolution in several classes of quantum devices is generated through the application of quantum gates. Resetting is a critical technological feature in these systems allowing for mid-circuit measurement and […]
Quantum 9, 1741 (2025). https://doi.org/10.22331/q-2025-05-13-1741 Quantum algorithms for Hamiltonian simulation and linear differential equations more generally have provided promising exponential speed-ups over classical computers on a set of problems with high real-world interest. However, extending […]
Quantum 9, 1740 (2025). https://doi.org/10.22331/q-2025-05-12-1740 Understanding how external driving and dissipation jointly influence the dynamics of open quantum systems is essential for advancing the study of non-equilibrium quantum phenomena and developing quantum technologies. The present […]
Quantum 9, 1739 (2025). https://doi.org/10.22331/q-2025-05-12-1739 In this work, we initiate the study of learning quantum processes from quantum statistical queries. We focus on two fundamental learning tasks in this new access model: shadow tomography of […]
Quantum 9, 1738 (2025). https://doi.org/10.22331/q-2025-05-12-1738 We describe a class of spin chains with new physical and computational properties. On the physical side, the spin chains give examples of symmetry-protected topological phases that are defined by […]
Quantum 9, 1737 (2025). https://doi.org/10.22331/q-2025-05-06-1737 Recent developments in domains such as non-local games, quantum interactive proofs, and quantum generative adversarial networks have renewed interest in quantum game theory and, specifically, quantum zero-sum games. Central to […]
Quantum 9, 1736 (2025). https://doi.org/10.22331/q-2025-05-06-1736 Quantum networks are of high interest nowadays and a quantum internet has been long envisioned. Network-entanglement adapts the notion of entanglement to the network scenario and network-entangled states are considered […]
