章 量子算術演算と量子論理演算
することにしましょう。このセクションでは、いくつかの低レベルのデジタル論理ゲートに相当する量
子論理ゲートを取り上げます。
5.9.1
基本的な量子論理ゲート
デジタル論理ゲートには、他のすべての演算を構築する基本論理ゲートがいくつか存在します。例
えば、
NAND
ゲートがあると、それを使用して
AND
、
OR
、
NOT
、
XOR
を作ることができます。そしてこ
れらを組み合わせると、任意の論理関数を作ることができます。
図5-22にある
NAND
ゲートは、任意の数の入力に対応できます。（最も単純な場合）
1
つの入力だけを
使えば、
NAND
で
NOT
演算を実行することになります。
図5-22
量子計算では、図 5-23のように
1
つの汎用ゲートから始め、そこから量子デジタル論理演算を構
築することができます。これを達成するには、複数条件の
CNOT
ゲート（トフォリゲート）を使います。
NAND
ゲートと同様に、実行される論理演算を拡張するために条件入力の数を変更できます（例5-6 参
照 ）。
