Quantum 10, 1962 (2026). https://doi.org/10.22331/q-2026-01-14-1962 We establish a unified statistical framework that underscores the crucial role statistical inference plays in Quantum Amplitude Estimation (QAE), a task essential to fields ranging from chemistry to finance and […]
Quantum 10, 1961 (2026). https://doi.org/10.22331/q-2026-01-08-1961 Self-testing identifies quantum states and correlations that exhibit nonlocality, distinguishing them, up to local transformations, from other quantum states. Due to their strong nonlocality, it is known that all graph […]
Quantum 10, 1960 (2026). https://doi.org/10.22331/q-2026-01-08-1960 We introduce a new framework for quantifying the complexity of quantum channels, grounded in a suitably chosen resource set. This class of convex functions is designed to analyze the complexity […]
Quantum 10, 1959 (2026). https://doi.org/10.22331/q-2026-01-07-1959 There has been a recent surge of interest within the field of quantum foundations regarding incorporating ideas from general relativity and quantum gravity. However, many quantum information tools remain agnostic […]
Quantum 9, 1958 (2025). https://doi.org/10.22331/q-2025-12-31-1958 Quantum networks are promising venues for quantum information processing. This motivates the study of the entanglement properties of the particular multipartite quantum states that underpin these structures. In particular, it […]
Quantum 9, 1957 (2025). https://doi.org/10.22331/q-2025-12-30-1957 Investigating the interplay of dualities, generalized symmetries, and topological defects beyond theoretical models is an important challenge in condensed matter physics and quantum materials. A simple model exhibiting this physics […]
Quantum 9, 1956 (2025). https://doi.org/10.22331/q-2025-12-24-1956 We investigate the emergence of quantum complexity and chaos in doped Clifford circuits acting on qudits of odd prime dimension $d$. Using doped Clifford Weingarten calculus and a replica tensor […]
Quantum 9, 1955 (2025). https://doi.org/10.22331/q-2025-12-23-1955 Topological data analysis has emerged as a powerful tool for analyzing large-scale data. An abstract simplicial complex, in principle, can be built from data points, and by using tools from […]
Quantum 9, 1954 (2025). https://doi.org/10.22331/q-2025-12-23-1954 Quantum Signal Processing (QSP), a framework for implementing matrix-valued polynomials, is a fundamental primitive in various quantum algorithms. Despite its versatility, a potentially underappreciated challenge is that all systematic protocols […]
Quantum 9, 1953 (2025). https://doi.org/10.22331/q-2025-12-22-1953 We describe and analyze LOBE (Ladder Operator Block-Encoding), a framework for block-encoding ladder operators that act upon fermionic and bosonic modes. In this framework, we achieve efficient block-encodings by applying […]
