Constant-overhead fault-tolerant quantum computation with reconfigurable atom arrays
Nature Physics, 2023Quantum low-density parity-check (qLDPC) codes can achieve high encoding rates and good code distance scaling, potentially enabling low-overhead fault-tolerant quantum computing. However, implementing qLDPC codes involves nonlocal operations that require

Realizing repeated quantum error correction in a distance-three surface code
Nature, 2021Quantum computers hold the promise of solving computational problems that are intractable using conventional methods1. For fault-tolerant operation, quantum computers must correct errors occurring owing to unavoidable decoherence and limited control ...

A universal qudit quantum processor with trapped ions
Nature Physics, 2021Most quantum computers use binary encoding to store information in qubits—the quantum analogue of classical bits. Yet, the underlying physical hardware consists of information carriers that are not necessarily binary, but typically exhibit a rich ...

A complex nonlinear approach for understanding quantum physics
International Journal of Quantum Information, 2020To understand quantum phenomena, namely, the particle-wave duality, in a causal relational way, a complex nonlinear process, in which a minor action may, under adequate conditions, give rise to a huge reaction, was proposed by de Broglie. The nonlinear process is mediated by the guiding or pilot wave principle, or as is now named by the principle of ...

Approaches on T/L Quantum Physics from PER Literature
2021Quantum mechanics has a paradigmatic role in twentieth-century physics for the theoretical foundation of the description of the world and important application and technological implications relevant also in everyday life. The Physics Education Research (PER) from many decades carried out researches on Teaching/Learning Quantum Physics (QP) from many ...

Cartesian Approach to Developing the Foundations of Quantum Physics
Journal of Physics & Optics Sciences, 2023In 1900, Planck presented an equation that became fundamental to quantum physics and paved the way for interpreting the nature of radiation. However, in a 1911 article where he attempted to theoretically justify this equation, some errors might have been introduced.

Approaches and Teaching Resources for Teacher Education in Quantum Physics
2023Quantum physics as a consolidated theory and with increasing applications and visions from quantum technologies is gaining importance also as a subject in schools. Efforts are increasing to introduce quantum physics in high school throughout Europe. These efforts must be underpinned by stringent teacher education, as well as by general education and ...

Qrisp: A Framework for Compilable High-Level Programming of Gate-Based Quantum Computers
arXiv.orgWhile significant progress has been made on the hardware side of quantum computing, support for high-level quantum programming abstractions remains underdeveloped compared to classical programming languages.
