Quantum technologies, devices that work by leveraging quantum mechanical effects, could outperform classical technologies in some fields and settings. The so-called spin (i.e., intrinsic angular momentum) carried by quantum particles is central to the functioning […]
Quantum 9, 1833 (2025). https://doi.org/10.22331/q-2025-08-27-1833 We significantly enhance the simulation accuracy of initial Trotter circuits for Hamiltonian simulation of quantum systems by integrating first-order Riemannian optimization with tensor network methods. Unlike previous approaches, our method […]
Quantum 9, 1832 (2025). https://doi.org/10.22331/q-2025-08-27-1832 Estimating the trace of quantum state powers, $text{Tr}(rho^k)$, for $k$ identical quantum states is a fundamental task with numerous applications in quantum information processing, including nonlinear function estimation of quantum […]
PhD in Relativistic Quantum Reference Frames at the University of South-Eastern Norway Submitted by Leon Loveridge on Wed, 27/08/2025 – 12:33. Application deadline: Friday, September 26, 2025 There is a fully funded PhD position in […]
Quantum 9, 1831 (2025). https://doi.org/10.22331/q-2025-08-27-1831 We investigate boundaries of 3D color codes and provide a systematic classification into 101 distinct boundary types, including two novel classes. The first class consists of 1 boundary and is […]
Researchers in Germany have unveiled the Metafiber, a breakthrough device that allows ultra-precise, rapid, and compact control of light focus directly within an optical fiber. Unlike traditional systems that rely on bulky moving parts, the […]
Quantum 9, 1830 (2025). https://doi.org/10.22331/q-2025-08-27-1830 Quantum networks allow for novel forms of quantum nonlocality. By exploiting the combination of entangled states and entangled measurements, strong nonlocal correlations can be generated across the entire network. So […]
Quantum 9, 1829 (2025). https://doi.org/10.22331/q-2025-08-27-1829 We propose several optimizations of the CliNR partial error correction scheme which implements Clifford circuits by consuming a resource state. Errors are corrected by measuring a sequence of Pauli operators […]
Quantum 9, 1828 (2025). https://doi.org/10.22331/q-2025-08-27-1828 Parametrised quantum circuits contain phase gates whose phase is determined by a classical algorithm prior to running the circuit on a quantum device. Such circuits are used in variational algorithms […]
