Title:
量子ビットを制御する量子ロジックコンポーネント及び方法
Document Type and Number:
Japanese Patent JP5426597
Kind Code:
B2
Abstract:
A component comprising a qubit and a controller for said qubit, said component comprising a quantum dot and an excitation portion configured to produce a neutral exciton state in said quantum dot to form said qubit, the component further comprising a measuring unit to make an optical measurement relating to the orientation of said state, wherein said controller comprises voltage source coupled to electrical contacts configured to apply a modulated electric field across said quantum dot, wherein the modulation is faster than the decay time of said neutral exciton state.
