Quantum world without queues could lead to better solar cells
In a recent study from Lund University in Sweden, researchers have used new technology to study extremely fast processes in solar cells. The research results form a concrete step towards more efficient solar cells.
Michelson-Morley experiment for electrons: Quantum-information techniques used to explore fundamental physics
A new experiment conducted at the University of California at Berkeley used quantum information techniques for a precision test of a cornerstone principle of physics, namely Lorentz invariance. This precept ...
Pushing quantum mechanics to higher levels
Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically -- but has up to five levels of energy instead of the usual two. The findings are published ...
Scientists uncover a photosynthetic puzzle
(Phys.org) -- Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied.
Tuning energy levels through surface chemistry shows promise for higher efficiency quantum dot solar cells
Solar cells made out of lead sulfide quantum dots could eventually offer a cheaper, more flexible alternative to ones made using silicon, but they are currently much less efficient. However, altering the ...
Researcher studies the universe through quantum electrodynamics
(PhysOrg.com) -- Fundamental constants, such as the standards for length and mass, are a given in our society. However, research has shown that these constants might be changing slightly with the expansion of the universe.
More energy efficient transistors through quantum tunneling
(PhysOrg.com) -- Researchers at the University of Notre Dame and Pennsylvania State University have announced breakthroughs in the development of tunneling field effect transistors (TFETs), a semiconductor ...
Ultra-short laser pulses control chemical processes
Specially shaped laser pulses can be used to change the state of electrons in a molecule. This process only takes several attoseconds—but it can initiate another, much slower process: The splitting of the ...
Finnish team devise nanomechanical microwave amplifier with near least possible noise generation
Building quantum states with individual silicon atoms
(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states.
Scientists provide 'new spin' on emerging quantum technologies
An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level.
Highly charged ions: Multiply-ionized atoms for clocks, qubits, and constants
The world is mostly neutral. That is, most of the atoms in our environment are electrically neutral. The number of electrons in the outer parts of atoms equals the number of protons at the centers of atoms. ...
