Abstract
(EN) In order to deterministically operate a quantum computing unit (13-m) in which a plurality of quantum systems are trapped, quantum computing is performed using a quantum computing unit including: a nano optical fiber (131-m) which is optically connected by way of a tapered portion to an optical fiber (12) through which incident photons propagate; and the plurality of quantum systems (132-m), which are arranged outside the nano optical fiber, and which are arranged spaced apart in the longitudinal direction of the nano optical fiber. However, at least any one of the quantum systems functions as a quantum bit that interacts with photons.
(FR) Afin de faire fonctionner de manière déterministe une unité de calcul quantique (13-m) dans laquelle une pluralité de systèmes quantiques sont piégés, un calcul quantique est effectué à l'aide d'une unité de calcul quantique comprenant : une nanofibre optique (131-m) qui est optiquement connectée, par l'intermédiaire d'une partie effilée, à une fibre optique (12) à travers laquelle se propagent des photons incidents ; la pluralité de systèmes quantiques (132-m), qui sont agencés à l'extérieur de la nanofibre optique, et qui sont agencés de façon à être espacés les uns des autres dans la direction longitudinale de la nanofibre optique. Cependant, au moins l'un quelconque des systèmes quantiques fonctionne comme un bit quantique qui interagit avec des photons.
(JA) 複数個の量子系をトラップした量子計算ユニット(13-m)を決定論的に動作させるために、入射された光子を伝搬する光ファイバー(12)にテーパー部を介して光学的に接続されたナノ光ファイバー(131-m)と、ナノ光ファイバーの外側に配置され、ナノ光ファイバーの長手方向に沿って間隔を置いて配置された複数の量子系(132-m)と、を有する量子計算ユニットを用いて量子計算を行う。ただし、少なくとも何れかの量子系は、光子と相互作用する量子ビットとして機能する。
