In an embodiment, the qubit tuning device includes a qubit of a quantum processor chip, wherein the first layer is configured to magnetically interact with the qubit such that a first magnetic flux of the first layer causes a first change in a first resonance frequency of the qubit by a first frequency shift value.

An embodiment of a method for qubit tuning includes generating a first magnetic field through a portion of a first layer, the first layer comprising a material exhibiting superconductivity in a cryogenic temperature range, the portion of the first layer above a critical temperature. In an embodiment, the method includes cooling the portion of the first layer at least to the critical temperature. In an embodiment, the method includes generating, in response to cooling the portion of the first layer at least to the critical temperature, a second magnetic field to magnetically interact with a qubit of a quantum processor chip such that a first magnetic flux of the first layer causes a first change in a first resonance frequency of the qubit by a first frequency shift value.

Plant eradication and stressing of plants using illumination trauma where a dual component, low energy, unnatural set of irradiances is applied, with no mutagenic or high radiative energy transfers in any wavelength for eradication by severe scalding, heat shock, or incineration. Two radiations are applied: an Indigo Region Illumination Distribution that can extend from 300 nm to 550 nm to be directed to plant foliage and/or a plant root crown, and a Medium Wavelength Infrared distribution of light, ranging from 2-20 microns wavelength to be directed to the ground, to a plant root crown and/or soil immediately adjacent the root crown. Plants can include seeds, and seedlings, and biomass can be irradiated to control weed seeds such as from a combine. The Indigo Region Illumination Distribution can pass through the MWIR emitter to form a compact illuminator. The MWIR emitter can comprise borosilicate glass at 400 F to 1000 F.

A heating system includes a sensing and tracking module to sense length in at least one dimension of an object to-be-heated in a previously determined area. A light source module has at least one light source that can change its lighting direction and can also change its beam angle e along the at least one dimension. A control module is provided for regulating light emitted by the light source module onto the to-be heated object along the at least one dimension to match with the length of the to-be-heated object based on the length sensed by the sensing and tracking module. The heating system described above and a bed incorporated having this kind of heating system may automatically adjust its output power according to the physical characteristics of the object to-be-heated to avoid heating unrelated object, area or space so as to ensure high energy efficiency.

An infrared light radiation device includes a radiation unit and a condenser. The radiation unit includes a heater and a metamaterial structure. The metamaterial structure is able to radiate, when heat energy is input from the heater, infrared light having a peak wavelength of a non-Planck distribution. The condenser includes at least one condensing lens that concentrates and transmits toward outside the infrared light radiated from the radiation unit.

A snow guard assembly heated within one or more snow guard tubes. Heating of the snow guard tube prevents excessive accumulation of snow and helps prevent snow build up and spill over above the top of the snow guard. The tubes can be length-wise separable to place and service the heating elements. The heating element can be standard heat tape or infrared LEDs. The snow guard tubes can optionally have a non-uniform cross-sectional thickness to direct the heat more efficiently in a desired orientation. The interior of the snow guard tubes can be selectively coated with infrared absorbing or reflective material to direct the heat in a desired orientation when infrared LEDs are used as a heat source. The snow guard can be attached to many types of roof surfaces including tile roofs, metal roofs with or without standing seams, and shingle roofs.

A drum for processing a thermal image medium has first and second end plates that extend orthogonally to an axis of rotation and enclose an inner core. First and second inner partitions along the axis define a first end zone between the first partition and the first end plate, a second end zone between the second partition and the second end plate, and a middle zone between the first and second partitions. Each inner partition has sleeve portions that extend outward from the partition, in an axial direction. A first lamp heater extends parallel to the axis and through one or more sleeve portions and has a first filament within the first end zone and a second filament within the second end zone. A second lamp heater extends parallel to the axis and through one or more sleeve portions and has a central filament within the middle zone.

Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.
