Quantum 10, 2000 (2026). https://doi.org/10.22331/q-2026-02-09-2000 While 2-level systems, aka qubits, are a natural choice to perform a logical quantum computation, the situation is less clear at the physical level. Encoding information in higher-dimensional physical systems […]
Quantum 10, 1999 (2026). https://doi.org/10.22331/q-2026-02-09-1999 The Sachdev–Ye–Kitaev (SYK) model is a prominent model of strongly interacting fermions that serves as a toy model of quantum gravity and black hole physics. In this work, we study […]
Quantum 10, 1998 (2026). https://doi.org/10.22331/q-2026-02-09-1998 We present a quantum variational algorithm based on a novel circuit that generates all permutations that can be spanned by one- and two-qubits permutation gates. The construction of the circuits […]
Quantum 10, 1997 (2026). https://doi.org/10.22331/q-2026-02-06-1997 We describe an efficient, fully fault-tolerant implementation of Measurement-Based Quantum Computation (MBQC) in the 3D cluster state. The two key novelties are (i) the introduction of a lattice defect in […]
Quantum 10, 1996 (2026). https://doi.org/10.22331/q-2026-02-06-1996 This work shows that minimizing the depth of a quantum circuit composed of commuting operations reduces to a vertex coloring problem on an appropriately constructed graph, where gates correspond to […]
Quantum 10, 1995 (2026). https://doi.org/10.22331/q-2026-02-03-1995 Characterizing entanglement of systems composed of multiple particles is a very complex problem that is attracting increasing attention across different disciplines related to quantum physics. The task becomes even more […]
Quantum 10, 1994 (2026). https://doi.org/10.22331/q-2026-02-03-1994 Unsupervised representation learning presents new opportunities for advancing Quantum Architecture Search (QAS) on Noisy Intermediate-Scale Quantum (NISQ) devices. QAS is designed to optimize quantum circuits for Variational Quantum Algorithms (VQAs). […]
