Einstein, in 1905, when he wrote the Annus Mirabilis papers. 1900 – To explain black-body radiation (1862), Max Planck suggests that electromagnetic energy could only be emitted in quantized form, i.e. the energy could only be a multiple of an elementary unit E = hν, where h is the Planck constant and ν is the frequency of the radiation.
A team at Delft University of Technology in the Netherlands creates a device that can manipulate the "up" or "down" spin-states of electrons on quantum dots. [77] The University of Arkansas develops quantum dot molecules. [78] The spinning new theory on particle spin brings science closer to quantum computing. [79]
The term quantum dot first appeared in a paper first authored by Mark Reed in 1986. [139] According to Brus, the term "quantum dot" was coined by Daniel S. Chemla while they were working at Bell Labs. [140]

On 13 December 2011, the rover began monitoring space radiation to aid in planning for future crewed missions to Mars. [32] The interplanetary journey to Mars took more than eight months, [33] time during which, the spacecraft performed four trajectory corrections: on 11 January, 26 March, 26 June and on 28 July. Mission design had allowed for ...
Silicon quantum dots are metal-free biologically compatible quantum dots with photoluminescence emission maxima that are tunable through the visible to near-infrared spectral regions. These quantum dots have unique properties arising from their indirect band gap , including long-lived luminescent excited-states and large Stokes shifts .
Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot.
