Quantum 10, 2057 (2026). https://doi.org/10.22331/q-2026-04-08-2057 We show that the Zassenhaus decomposition for the exponential of the sum of two non-commuting operators, simplifies drastically when these operators satisfy a simple condition, called the no-mixed adjoint property. […]
Quantum 10, 2056 (2026). https://doi.org/10.22331/q-2026-04-08-2056 We devise a deterministic quantum algorithm to produce antisymmetric states of single-particle orbitals in the first quantization mapping. Unlike sorting-based antisymmetrization algorithms, which require ordered input states and high Clifford-gate […]
Quantum 10, 2055 (2026). https://doi.org/10.22331/q-2026-04-08-2055 High-throughput characterization often requires estimating parameters and model dimension from experimental data of limited quantity and quality. Such data may result in an ill-posed inverse problem, where multiple sets of […]
Quantum 10, 2054 (2026). https://doi.org/10.22331/q-2026-04-08-2054 Power-law probability distributions are widely used to model extreme statistical events in complex systems, with applications to a vast array of natural phenomena ranging from earthquakes to stock market crashes […]
Quantum 10, 2053 (2026). https://doi.org/10.22331/q-2026-04-08-2053 Fermionic averaged circuit eigenvalue sampling (FACES) is a protocol to simultaneously learn the averaged error rates of many fermionic linear optical (FLO) gates simultaneously and self-consistently from a suitable collection […]
Quantum 10, 2052 (2026). https://doi.org/10.22331/q-2026-04-08-2052 Quantum resources, such as entanglement or quantum communication, offer significant communication advantages in information processing. We develop an operational framework for realizing these communication advantages in resource-constrained quantum networks. The […]
Quantum 10, 2051 (2026). https://doi.org/10.22331/q-2026-04-01-2051 Maximal sets of mutually unbiased bases are useful throughout quantum physics, both in a foundational context and for applications. To date, it remains unknown if complete sets of mutually unbiased […]
Quantum 10, 2050 (2026). https://doi.org/10.22331/q-2026-04-01-2050 We propose a class of metrological resource states whose quantum Fisher information scales optimally in both system size and noise rate. In these states, qubits are partitioned into sensing groups […]
Quantum 10, 2049 (2026). https://doi.org/10.22331/q-2026-04-01-2049 The conditional disclosure of secrets (CDS) setting is among the most basic primitives studied in information-theoretic cryptography. Motivated by a connection to non-local quantum computation and position-based cryptography, CDS with […]
Quantum 10, 2048 (2026). https://doi.org/10.22331/q-2026-03-27-2048 Quantum signal processing and quantum singular value transformation are powerful tools to implement polynomial transformations of block-encoded matrices on quantum computers, and has achieved asymptotically optimal complexity in many prominent […]
