QUANTUM CODE DESIGN APPARATUS CAPABLE OF IMPROVING THE PERFORMANCE OF A QUANTUM ERROR CORRECTION CODE AND A METHOD THEREOF

摘要

PURPOSE: A quantum code design apparatus capable of improving the performance of a quantum error correction code and a method thereof are provided to apply an entangled cubit to the design technique of a CWS(Code Word Stabilized Quantum) code, thereby enabling designing of the quantum error correction code.;CONSTITUTION: An analysis part(110) analyzes more than one quantum error generated in a quantum error channel as a binary error using the standard form of a CWS code. A code generation part(120) generates a binary error correction code correcting more than one binary error. A word operator generating part(130) generates more than one word operator of the CWS code using more than one binary error correction code. A code word generating part(140) generates more than one code word including more than one entangled cubit using more than one word operator.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Analysis part; (120) Code generation part; (130) Word operator generating part; (140) Code word generating part
