Abstract
A quantum dot manipulating method and a generation/manipulation apparatus are provided which can control the size of a large number of generated quantum dots on or below the order of percent which is required for optical applications of the dots. Quantum dots are generated by shining a dot production laser (4a) onto a solid object (3) in a quantum dot production/manipulation apparatus (1) containing superfluid helium (7) therein. A dot manipulation laser (5a) is shone onto the generated quantum dots to manipulate the quantum dots.

A quantum dot production/manipulation apparatus, comprising:
- a housing having an internal space to enable quantum dot generation and manipulation;
- a solid object holding section, provided inside the housing, to hold a solid object of a quantum dot material;
- and
- a dot production laser source shining a laser onto a solid object held in the solid object holding section to generate quantum dots by laser sputtering;
- and
- a dot manipulation laser source shining a laser onto the generated quantum dots to manipulate the quantum dots,
- wherein the housing is adapted to hold superfluid helium in the internal space.
