To solve problems of practical importance, quantum computers probably need to incorporate quantum error correction, in which a logical qubit is redundantly encoded in many noisy physical qubits. The large physical-qubit overhead associated with error correction motivates the search for more hardware-efficient approaches. Here, using a superconducting quantum circuit, we realize a logical qubit memory formed from the concatenation of encoded bosonic cat qubits with an outer repetition code of distance d = 5 (ref.

Methods: Selected groups from two cohorts (cohort 1 of 307 healthy volunteers and cohort 2 of 218 coronary heart disease [CHD] patients). COVID-19 infection was confirmed by detection of IgG-SARS against SARS-CoV-2 S1 protein receptor-binding domain.
This paper proposes and implements a novel scheme for recording signals from fibre optic sensors based on tandem low-coherence interferometry with an integrated optical reference interferometer. The circuit allows precision control of the phase shift. Additionally, the paper illustrates the potential for detecting vibration and object deformation using fibre optic Fabry-Perot sensors connected to the registration system.

It is a known fact that insecticides can have a harmful effect on the legume-rhizobial symbiosis. In this study, the effects of systemic seed treatment insecticide Imidor Pro (imidacloprid) and foliar insecticide Faskord (alpha-cypermethrin) on the structural organization of pea ( L.

- Low-dimensional quantum systems can support unique particles called anyons that behave differently from traditional particles like bosons and fermions, particularly in one dimension.
- This study successfully creates Abelian anyons using ultracold atoms in an optical lattice and investigates their behavior, including quantum walks and a specific interference effect known as the Hanbury Brown-Twiss effect.
- When interactions among the anyons are introduced, they exhibit different transport dynamics compared to bosons and fermions, paving the way for future research into complex behaviors of one-dimensional anyons.
