Now it seems that pigments used in photosynthesis
use quantum calculations to harness light (see «Hot green quantum computers revealed»).
Neutron scattering has revealed in unprecedented detail new insights into the exotic magnetic behavior of a material that, with a fuller understanding, could pave the way
for quantum calculations far beyond the limits of the ones and zeros of a computer's binary code.
A group of Michigan State University researchers specializing
in quantum calculations has proposed a radically new computational approach to solving the complex many - particle Schrödinger equation, which holds the key to explaining the motion of electrons in atoms and molecules.
A trio of electrons, the building blocks of classical computers, were entangled in a semiconductor in 2003, and the
first quantum calculation was made with a single calcium ion in 2002.
The new chip design, published in the journal Nature Communications, details a novel architecture that
allows quantum calculations to be performed using existing semiconductor components, known as CMOS (complementary metal - oxide - semiconductor)-- the basis for all modern chips.
The team's
quantum calculations confirmed the predictions of a simplified version of quantum electrodynamics, the established theory of the electromagnetic force.
Ironically, while the protection system developed complex
blood quantum calculations to decide «how Aboriginal» individuals were, they had no regard for the existing tribal, clan and family group divisions that are important markers of culture and identity.
In your editorial on quantum biology, you write that «the pigments used in photosynthesis
use quantum calculations» (6 February, p...
That could make them useful for
performing quantum calculations of the sort that might break codes and solve problems in chemistry and physics that are too complicated to solve with even the largest supercomputer.
When the state vector is unknown,
quantum calculations use a density matrix to compute the odds of different measurement outcomes.
Last year, Princeton physicist Nima Arkani - Hamed was analyzing the formulas in search of a better way to simplify
these quantum calculations.
A quantum calculation able to crack one of the most common forms of data encryption has been performed on a silicon chip for the first time.
But before you go looking for a cosmic connection or buy any crystals, relax: There is probably no deep meaning to the slice of π from
the quantum calculation.
