Quantum 9, 1852 (2025). https://doi.org/10.22331/q-2025-09-08-1852 We propose a systematic framework to construct a $(d+1)$-dimensional stabilizer model from an initial generic d-dimensional abelian symmetry. Our approach builds upon the iterative gauging procedure, developed by one of […]
Quantum 9, 1851 (2025). https://doi.org/10.22331/q-2025-09-05-1851 Local Friendliness (LF) inequalities follow from seemingly reasonable assumptions about reality: (i) “absoluteness of observed events” (e.g., every observed event happens for all observers) and (ii) “local agency” (e.g., free […]
Quantum 9, 1850 (2025). https://doi.org/10.22331/q-2025-09-05-1850 We study simultaneous symmetry breaking in spontaneous Floquet states, focusing on the specific case of an atomic condensate. We first describe the quantization of the Nambu-Goldstone (NG) modes for a […]
Quantum 9, 1849 (2025). https://doi.org/10.22331/q-2025-09-05-1849 A central goal in quantum error correction is to reduce the overhead of fault-tolerant quantum computing by increasing noise thresholds and reducing the number of physical qubits required to sustain […]
Quantum 9, 1848 (2025). https://doi.org/10.22331/q-2025-09-05-1848 Randomized benchmarking (RB) protocols are widely used to measure an average error rate for a set of quantum logic gates. However, the standard version of RB is limited because it […]
Quantum 9, 1847 (2025). https://doi.org/10.22331/q-2025-09-03-1847 In this work, we highlight an unforeseen behavior of the expressivity of Parameterized Quantum Circuits (PQCs) for machine learning. A large class of these models, seen as Fourier series whose […]
Quantum 9, 1846 (2025). https://doi.org/10.22331/q-2025-09-03-1846 Code switching is an established technique that facilitates a universal set of FT quantum gate operations by combining two QEC codes with complementary sets of gates, which each by themselves […]
Quantum 9, 1845 (2025). https://doi.org/10.22331/q-2025-09-03-1845 We consider introducing the Dirac sea in a quantum cellular automata model of fermions in discrete spacetime which approximates the Dirac equation in the continuum limit. However, if we attempt […]
Quantum 9, 1844 (2025). https://doi.org/10.22331/q-2025-09-03-1844 Generalizing the well-known spin-squeezing inequalities, we study the relation between squeezing of collective $N$-particle $su(d)$ operators and many-body entanglement geometry in multi-particle systems. For that aim, we define the set […]
Quantum 9, 1843 (2025). https://doi.org/10.22331/q-2025-08-29-1843 Building upon recent progress in Lindblad engineering for quantum Gibbs state preparation algorithms, we propose a simplified protocol that is shown to be efficient under the eigenstate thermalization hypothesis (ETH). […]
