Editing Quantum information (section)

==== Development from information theory ====
Around the time computer science was making a revolution, so was information theory and communication, through [[Claude Shannon]].<ref name="Shannon1948a"/><ref name="Shannon1948b"/><ref name="Shannon1964"/> Shannon developed two fundamental theorems of information theory: noiseless channel coding theorem and [[Noisy-channel coding theorem|noisy channel coding theorem]]. He also showed that [[Error correction code|error correcting codes]] could be used to protect information being sent.

Quantum information theory also followed a similar trajectory, Ben Schumacher in 1995 made an analogue to Shannon's [[Shannon's source coding theorem|noiseless coding theorem]] using the [[qubit]]. A theory of error-correction also developed, which allows quantum computers to make efficient computations regardless of noise and make reliable communication over noisy quantum channels.<ref name="Nielsen2010" />
