1. A quantum computing system comprising:
a planar substrate of a direct or indirect semiconductor material;
a microelectronic circuit which is part of the substrate;
an electrical component which is part of the microelectronic circuit, wherein the microelectronic circuit includes at least one transistor or at least one diode;
a micro-optical subdevice which is part of the planar substrate, such that the planar substrate thus includes the microelectronic circuit and the electrical component and the micro-optical subdevice;
at least a first aligned nanoparticle and a second aligned nanoparticle, each aligned nanoparticle having one or more color centers, and each aligned nanoparticle comprising an alignment aid, wherein the alignment aid determines alignment of at least one axis of the aligned nanoparticle; and
at least a first portion of a solidified colloidal film, wherein at least the first aligned nanoparticle is comprised within the first portion of the solidified colloidal film;
wherein:
the first portion of the solidified colloidal film comprising at least the first aligned nanoparticle is firmly bonded to the planar substrate;
the system further comprises at least one light-emitting electro-optical component which is part of the planar substrate or is fabricated on the surface of the planar substrate;
the light-emitting electro-optical component interacts optically with the micro-optical subdevice;
the light-emitting electro-optical component interacts electrically and/or optically with the electrical component in a direct or indirect manner based on the interaction with the micro-optical subdevice; and
the interaction between the light-emitting electro-optical component and the electrical component takes place with an involvement of the color center or a plurality of color centers.
