Quantum algorithm of the direct calculation of energy derivatives developed for molecular geometry optimization      (via sciencedaily.com) 

Researchers have successfully extended the quantum phase difference estimation algorithm, a general quantum algorithm for the direct calculations of energy gaps, to enable the direct calculation of energy differences between two different molecular geometries. This allows for the computation, based on the finite difference method, of energy derivatives with respect to nuclear coordinates in a single calculation.

Old World flycatchers' family tree mapped      (via sciencedaily.com)     Original source 

The European robin's closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 per cent of the more than 300 species in this family.

Spin correlation between paired electrons demonstrated      (via sciencedaily.com)     Original source 

Physicists have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. For their study, the researchers used spin filters made of nanomagnets and quantum dots.

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.

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.

What shapes the composition of microbes in a warbler's gut?      (via sciencedaily.com)     Original source 

Differences among the collection of bacteria and other microorganisms that live within birds' digestive tracts -- their gut microbiomes -- are not primarily driven by diet diversity, contrary to a recently proposed hypothesis. Instead, a team of researchers found that evolution may play a larger role in explaining these differences, which could potentially have implications for how these species adapt to new habitats.

Grid of quantum islands could reveal secrets for powerful technologies      (via sciencedaily.com)     Original source 

Researchers have created grids of tiny clumps of atoms known as quantum dots and studied what happens when electrons dive into these archipelagos of atomic islands. Measuring the behavior of electrons in these relatively simple setups promises deep insights into how electrons behave in complex real-world materials and could help researchers engineer devices that make possible powerful quantum computers and other innovative technologies.

Planting trees can save lives, study shows      (via sciencedaily.com)     Original source 

A 30-year tree planting campaign in Portland, Oregon, allowed researchers to show that the number of trees planted in the street is associated with reductions in mortality, and that the association grows stronger as the trees age and grow.
