For their study, the researchers used spin filters made of nanomagnets and quantum dots.
Published Scientists convert waste paper into battery parts for smartphones and electric vehicles
(via sciencedaily.com) Scientists have developed a technique to convert waste paper, from single-use packaging and bags, and cardboard boxes, into a crucial component of lithium-ion batteries. Through a process called carbonisation which converts paper into pure carbon, the researchers turned the paper's fibers into electrodes, which can be made into rechargeable batteries that power mobile phones, medical equipment, and electric vehicles.
Published Quantum algorithms save time in the calculation of electron dynamics
(via sciencedaily.com) Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, quantum computer algorithms can already run on conventional servers that simulate a quantum computer. A team has succeeded in calculating the electron orbitals and their dynamic development using an example of a small molecule after a laser pulse excitation. In principle, the method is also suitable for investigating larger molecules that cannot be calculated using conventional methods.
Published Microlaser chip adds new dimensions to quantum communication
(via sciencedaily.com) With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.
