A method for controlling a qubit encoded in an atom-like defect in a solid-state host may comprise applying an electrical signal to a piezoelectric cantilever that is mechanically coupled to a photonic waveguide comprising one or more embedded point defect sites. The photonic waveguide may be optically coupled to a photonic chip. Applying the electrical signal to the piezoelectric cantilever may induce movement in the piezoelectric cantilever, which may induce a strain in the photonic waveguide. The applied electrical signal may be determined by a defect site with excitation light, measuring a frequency of a photon emitted by the excited defect site, determining a frequency shift based on the measured frequency of the emitted photon, and determining the electrical signal to be applied to the piezoelectric cantilever based on the frequency shift.

Some embodiments of the invention comprises a one-way mirror, while others comprise a variable transparency film. Preferred embodiments, however, comprise both a one-way mirror and a variable transparency film that work cooperatively to provide a lid that is see through when viewed from the outside, and reflective when viewed from the inside.

Described herein is a polymorphic display, which is a unitary apparatus constructed such that a wide variety of electro-optic functions are enabled. The polymorphic display, even when having multiple pixels, enables sharing of selected structures among the pixels. In a multi-pixel construction, there is a set of pixels in the display that exhibit one set of operable properties, such as particular stability, sequencing, and switching properties, and another set of pixels that are different from the first set. That is, they have different stability, sequencing, or switching properties. In such a way, a highly flexible polymorphic display may be construed to satisfy a wide range of display needs.
