That these codes allow indeed for quantum computations of arbitrary length is the content of the quantum threshold theorem, found by Michael Ben-Or and Dorit Aharonov, which asserts that you can correct for all errors if you concatenate quantum codes such as the CSS codes—i.e. re-encode each logical qubit by the same code again, and so on, on ...
Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.
In the 1940s, they supplied disabled veterans of World War II through government contracts that established the company as a recognized name in rehabilitation equipment. [ 5 ] [ 6 ] [ 7 ] The Everest family sold its interest in the company in 1943, [ 8 ] but Gerald Jennings, son of Harry Sr., was chief executive from 1952 until he retired in 1985.
Relativistic quantum chemistry combines relativistic mechanics with quantum chemistry to calculate elemental properties and structure, especially for the heavier elements of the periodic table. A prominent example is an explanation for the color of gold : due to relativistic effects, it is not silvery like most other metals.
Higher deflection power means more current [283] is sent to the deflection coils to bend the electron beam at a higher angle, [111] which in turn may generate more heat or require electronics that can handle the increased power. [282] Heat is generated due to resistive and core losses. [284] The deflection power is measured in mA per inch. [249]
A motorized wheelchair, powerchair, electric wheelchair, or electric-powered wheelchair (EPW) is a wheelchair that is propelled by means of an electric motor (usually using differential steering) rather than manual power. Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for ...
A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
The Red and Blue Chair is a chair designed in 1917 by Gerrit Rietveld. It represents one of the first explorations by the De Stijl art movement in three dimensions. It features several Rietveld joints. The original chair was constructed of unstained beech wood and was not painted red, blue, yellow, and black until around 1923.
