Quantum 9, 1609 (2025). https://doi.org/10.22331/q-2025-01-27-1609 Two-dimensional color codes are a promising candidate for fault-tolerant quantum computing, as they have high encoding rates, transversal implementation of logical Clifford gates, and resource-efficient magic state preparation schemes. However, […]
Quantum 9, 1608 (2025). https://doi.org/10.22331/q-2025-01-27-1608 In the quest for robust and universal quantum devices, the notion of simulation plays a crucial role, both from a theoretical and from an applied perspective. In this work, we […]
Quantum 9, 1607 (2025). https://doi.org/10.22331/q-2025-01-23-1607 We investigate mixed states exhibiting nontrivial topological features, focusing on symmetry-protected topological (SPT) phases under various types of decoherence. Our findings demonstrate that these systems can retain topological information from […]
Quantum 9, 1606 (2025). https://doi.org/10.22331/q-2025-01-23-1606 Quantum learning tasks often leverage randomly sampled quantum circuits to characterize unknown systems. An efficient approach known as “circuit reusing,” where each circuit is executed multiple times, reduces the cost […]
Quantum 9, 1605 (2025). https://doi.org/10.22331/q-2025-01-21-1605 Entanglement-based quantum networks exhibit a unique flexibility in the choice of entangled resource states that are then locally manipulated by the nodes to fulfill any request in the network. Furthermore, […]
Quantum 9, 1604 (2025). https://doi.org/10.22331/q-2025-01-21-1604 A quantum position-verification scheme attempts to verify the spatial location of a prover. The prover is issued a challenge with quantum and classical inputs and must respond with appropriate timings. […]
Quantum 9, 1603 (2025). https://doi.org/10.22331/q-2025-01-21-1603 Quantum state purification is the task of recovering a nearly pure copy of an unknown pure quantum state using multiple noisy copies of the state. This basic task has applications […]
Quantum 9, 1602 (2025). https://doi.org/10.22331/q-2025-01-20-1602 In the last two decades, there has been much effort in finding secure protocols for two-party cryptographic tasks. It has since been discovered that even with quantum mechanics, many such […]
Quantum 9, 1601 (2025). https://doi.org/10.22331/q-2025-01-20-1601 Split Cayley hexagons of order two are distinguished finite geometries living in the three-qubit symplectic polar space in two different forms, called classical and skew. Although neither of the two […]
Quantum 9, 1600 (2025). https://doi.org/10.22331/q-2025-01-20-1600 In this work, we introduce a fast implementation of the minimum-weight perfect matching (MWPM) decoder, the most widely used decoder for several important families of quantum error correcting codes, including […]
