Spin Qubits can be Potentially Useful for Quantum Networks that Employ Optical Fibers

Quantum computers may be able to solve science problems that are impossible for today's fastest conventional supercomputers. Quantum sensors may be able to measure signals that cannot be measured by today's most sensitive sensors. Quantum bits (qubits) are the building blocks for these devices.

Research Could Open Up a New Route for the Realization of High-Mobility Organic Optoelectronics

Semiconductor electronic devices can be made of either inorganic crystals, formed by the strong bonding of atoms and ions, or organic crystals, which demonstrate weaker bonds held together by van der Waals forces (weak electric forces of attraction between neutral atoms or molecules that do not share a chemical bond).

Chemists Improve the Stability of Perovskite Solar Cells Using Passivation Method

A group of chemists from Kaunas University of Technology (KTU), Lithuania synthesised materials that were used for constructing a record-breaking perovskite solar module, with an efficiency of 21.4 per cent. This was achieved through the passivation of the active solar cell layer, which increases the efficiency of the cell and significantly improves its stability.

New Method to Rapidly Design CdSe Thin-Film Solar Cells

Si-based tandem solar cell is regarded as the most promising strategy to break the theoretical efficiency limit of single-junction Si solar cells. With Si as the bottom cells, the optimal bandgap of top cells is 1.7 eV, which enables high efficiency of ~45% for two-junction tandem solar cells.

Experimental Realization of Atom-Optically Synthetic Gauge Field for a Noninteracting Bose Gas

Gauge fields describe the basic interactions between charged particles and are responsible for various emergent topological phases of matter. This concept recently has been further generalized to charge neutral systems by engineering an analog Hamiltonian that governs the effective dynamics of neutral particles subject to magnetic fields.
