Quantum 7, 1211 (2023). https://doi.org/10.22331/q-2023-12-20-1211 Many-particle quantum systems with intermediate anyonic exchange statistics are supported in one spatial dimension. In this context, the anyon-anyon mapping is recast as a continuous transformation that generates shifts of […]
Quantum 7, 1210 (2023). https://doi.org/10.22331/q-2023-12-20-1210 The widespread success of deep neural networks has revealed a surprise in classical machine learning: very complex models often generalize well while simultaneously overfitting training data. This phenomenon of benign […]
Quantum 7, 1209 (2023). https://doi.org/10.22331/q-2023-12-18-1209 We introduce a neural network-based approach for modeling wave functions that satisfy Bose-Einstein statistics. Applying this model to small $^4He_N$ clusters (with N ranging from 2 to 14 atoms), we […]
Quantum 7, 1208 (2023). https://doi.org/10.22331/q-2023-12-18-1208 We give a novel procedure for approximating general single-qubit unitaries from a finite universal gate set by reducing the problem to a novel magnitude approximation problem, achieving an immediate improvement […]
Quantum 7, 1207 (2023). https://doi.org/10.22331/q-2023-12-14-1207 In quantum key distribution (QKD), protocols are tailored to adopt desirable experimental attributes, including high key rates, operation in high noise levels, and practical security considerations. The round-robin differential phase […]
Quantum 7, 1206 (2023). https://doi.org/10.22331/q-2023-12-12-1206 Learning a hidden property of a quantum system typically requires a series of interactions. In this work, we formalise such multi-round learning processes using a generalisation of classical-quantum states, called […]
Quantum 7, 1205 (2023). https://doi.org/10.22331/q-2023-12-12-1205 We describe a pipeline approach to decoding the surface code using minimum weight perfect matching, including taking into account correlations between detection events. An independent no-communication parallelizable processing stage reweights […]
Quantum 7, 1204 (2023). https://doi.org/10.22331/q-2023-12-12-1204 Photons are the physical system of choice for performing experimental tests of the foundations of quantum mechanics. Furthermore, photonic quantum technology is a main player in the second quantum revolution, […]
Quantum 7, 1203 (2023). https://doi.org/10.22331/q-2023-12-11-1203 Quantum information-processing techniques enable work extraction from a system’s inherently quantum features, in addition to the classical free energy it contains. Meanwhile, the science of computational mechanics affords tools for […]
Quantum 7, 1202 (2023). https://doi.org/10.22331/q-2023-12-06-1202 We describe a simple algorithm for estimating the $k$-th normalized Betti number of a simplicial complex over $n$ elements using the path integral Monte Carlo method. For a general simplicial […]
