Chasing Charge Carriers: Diffusion Dynamics in Mixed‐n Quasi‐2D Colloidal MAPbBr3 Perovskites
Advanced Functional Materials, EarlyView.Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transport behavior. Three MAPbBr3 morphologies are characterized: nanoplatelets, nanosheets, and nanostripes.

Transversal diagonal logical operators for stabiliser codes
New Journal of Physics, 2023 Storing quantum information in a quantum error correction code can protect it from errors, but the ability to transform the stored quantum information in a fault tolerant way is equally important.

Demonstration of teleportation-based error correction in the IBM quantum computer [PDF]
arXiv, 2019 Quantum error correcting codes (QECC) are the key ingredients both for fault-tolerant quantum computation and quantum communication. Teleportation-based error correction (TEC) helps in detecting and correcting operational and erasure errors by performing X and Z measurements during teleportation.

A note on threshold theorem of fault-tolerant quantum computation [PDF]
arXiv, 2010 Error-correction process has to be carried out periodically to prevent accumulation of errors in fault-tolerant quantum computation. It is believed that the best choice to get maximum threshold value is carrying out an error-correction process after each quantum gate operation.

Superselection Rules, Quantum Error Correction, and Quantum Chromodynamics [PDF]
arXiv, 2023 We investigate the relationship between superselection rules and quantum error correcting codes. We demonstrate that the existence of a superselection rule implies the Knill-Laflamme condition in quantum error correction. As an example, we examine quantum chromodynamics through the lens of quantum error correction, where the proton and neutron states ...

Identification and Reversible Optical Switching of NV+ Centers in Diamond
Advanced Functional Materials, EarlyView.NV+ centers in diamond are predicted to coexist with NV0 and NV– centers, but direct experimental confirmation remains challenging. Using positron annihilation spectroscopy with in situ light illumination, a charge transition NV+/0 is observed at 1.234(8) eV.

Quantum Error Correcting Subsystem Codes From Two Classical Linear Codes [PDF]
arXiv, 2006 The essential insight of quantum error correction was that quantum information can be protected by suitably encoding this quantum information across multiple independently erred quantum systems. Recently it was realized that, since the most general method for encoding quantum information is to encode it into a subsystem, there exists a novel form of ...

High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite
Advanced Functional Materials, EarlyView.This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.
