Experimental Realization
There have been several experimental realizations of CSS-based codes. The first demonstration was with NMR qubits. Subsequently demonstrations have been made with linear optics, trapped ions, and superconducting (transmon) qubits.
Other error correcting codes have also been implemented, such as one aimed at correcting for photon loss, the dominant error source in photonic qubit schemes.

Famous quotes containing the words experimental and/or realization:
“When we run over libraries persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames; for it can contain nothing but sophistry and illusion.”
—David Hume (1711–1776)
“The ground for taking ignorance to be restrictive of freedom is that it causes people to make choices which they would not have made if they had seen what the realization of their choices involved.”
—A.J. (Alfred Jules)
