🎓 In Quantum Mechanics an orbital is a mathematical function which portrays the wave-like behavior of an electron pair, electron or nucleons.
Atomic orbitals are the 3D regions of space around the nucleus of an atom. Atomic orbitals allow the atoms to make covalent bonds. s, p, d and f orbitals are the most commonly filled orbitals. These orbitals have a variety of shapes. As defined by the Pauli Exclusion Principle, only two electrons can be found in any orbital space.
But there are also nodes. Node is a region where the probability of finding the electron will be zero. The nodal plane is the plane that passes through the nucleus on which the probability of finding an electron is zero.

Light emitters for quantum circuits.
The promise of a quantum internet depends on harnessing light to transmit information over fiber optic networks. Researchers in Sweden have developed integrated chips emit single photons on demand without the need for low temperatures.
The work is published in the journal Advanced Quantum Technologies: https://onlinelibrary.wiley.com/doi/10.1002/qute.202100032

Liquid light.
Researchers at St. Petersburg State University have experimentally observed the formation of a Bose-Einstein condensate in molybdenum diselenide. The condensate contains thousands of exciton polaritons, or ‘liquid light’ quanta, which can be used to carry information in quantum computing applications.
The work has recently been published in Nature Materials: https://www.nature.com/articles/s41563-021-01000-8

Visualizing atomic-scale structures with the optical force.
Researchers from Osaka University have achieved the first ever sub-nanometre resolution in photoinduced atomic force microscopy. They eliminated noise sources to map out the forces acting on quantum dots in 3D with a precision never previously achieved.

Quantum random numbers.
Most random numbers aren’t truly random. However, using quantum computers can achieve levels of randomness only limited by the basic laws of quantum physics. Researchers at the University of Science and Technology of China have built the fastest known real-time quantum random number generator by combining state-of-the-art photonic integration with advanced post-processing technologies.
Their machine is described in Applied Physics Letters: https://aip.scitation.org/doi/10.1063/5.0056027
