Quantum 10, 2204 (2026). https://doi.org/10.22331/q-2026-09-03-2204 When simulating the dynamics of open quantum systems with quantum computers, it is essential to accurately approximate the system’s behaviour while preserving the physicality of its evolution. Traditionally, for Markovian […]
Quantum 10, 2203 (2026). https://doi.org/10.22331/q-2026-09-03-2203 Quantum Max Cut (QMC) problem for systems of qubits is an example of a 2-local Hamiltonian problem, and a prominent paradigm in computational complexity theory. This paper investigates the algebraic […]
Quantum 10, 2202 (2026). https://doi.org/10.22331/q-2026-09-03-2202 Stabiliser codes with large weight measurements can be challenging to implement fault-tolerantly. To overcome this, we propose a Floquetification procedure which, given a stabiliser code, synthesises a novel Floquet code […]
Quantum 10, 2201 (2026). https://doi.org/10.22331/q-2026-09-02-2201 Focusing on the real-time dynamics of the reduced density matrix of the multidimensional Caldeira-Leggett model, several techniques are adopted in this paper to reduce the spatial and temporal dimensionality, combined […]
Quantum 10, 2200 (2026). https://doi.org/10.22331/q-2026-09-02-2200 The study of real time dynamics of nuclear systems is of great importance to provide theoretical predictions of cross sections relevant for both terrestrial experiments as well as applications in […]
Quantum 10, 2199 (2026). https://doi.org/10.22331/q-2026-09-01-2199 We study symmetry-enriched topological order in two-dimensional tensor network states by using graded matrix product operator algebras to represent symmetry-induced domain walls. A close connection to the theory of graded […]
Quantum 10, 2198 (2026). https://doi.org/10.22331/q-2026-09-01-2198 In this review article we summarize all experiments claiming quantum computational advantage to date. Our review highlights challenges, loopholes, and refutations appearing in subsequent work to provide a complete picture […]
Quantum 10, 2197 (2026). https://doi.org/10.22331/q-2026-08-27-2197 Atomic scale qubits, as may be realized in nitrogen vacancy (NV) centers in diamond, offer the opportunity to study magnetic field noise with nanometer scale spatial resolution. Using these spin […]
Quantum 10, 2196 (2026). https://doi.org/10.22331/q-2026-08-20-2196 The framework of internal quantum reference frames (QRFs) constitutes a universal toolset for dealing with symmetries in quantum theory and has led to new revelations in quantum gravity, gauge theories […]
Quantum 10, 2195 (2026). https://doi.org/10.22331/q-2026-08-19-2195 There have been significant recent advances in constructing theoretical and practical quantum error correcting codes that function well as quantum memories; however, performing fault-tolerant logical gates on these codes is […]
