Systems and methods for the optical control of qubits and other quantum particles with spatial light modulators (SLM) for quantum computing and quantum simulation are disclosed herein. The system may include a particle system configured to provide an ordered array comprising a multiplicity of quantum particles or a multiplicity of qubits, an optical source, a SLM configured to project a structured illumination pattern capable of individually addressing one or more quantum particles or qubits of the ordered array, and a SLM controller.

Optical control of qubits with spatial light modulators for quantum computing and quantum simulation

An apparatus and method for linewidth broadening applied to a laser that emits a light having an output frequency &#x3bd; and an emission linewidth &#x3b4;. The apparatus is equipped with an electro-optic modulator for intercepting the light and a noise generator for driving the electro-optic modulator with a radio-frequency (RF) noise signal spanning a frequency range selected to broaden the emission linewidth &#x3b4;of the light passing through the electro-optic modulator to a broadened linewidth &#x3b4;. The noise spectrum of the noise signal exhibits a continuous frequency range and can be flat or sloping. The range extends from low frequency &#x3c9;set below the emission linewidth &#x3b4;of the light to a high frequency &#x3c9;set above the emission linewidth &#x3b4;of the light. The electro-optic modulator can be selected from among many suitable devices including optical crystals. Further broadening can be achieved by employing one or more secondary EOMs operating in resonant or non-resonant modes. The lasers that benefit from the invention involve any type of inherently narrow bandwidth lasers operating in CW or pulsed modes.

Laser coherence control using homogeneous linewidth broadening

The present invention provides a method and apparatus for packaging high frequency electrical and/or electro-optical components. The present invention provides a package which may be surface mounted on a board with other electrical components. The shielding provided by the package minimizes electromagnetic interference with other electrical components on the board. The package includes a controlled impedance I/O interface for coupling with the electrical and/or electro-optical component(s) in the package. The package interface may also include a differential I/O capability to further control electromagnetic fields generated at the interface. Additionally, the package may include an optical link provided by one or more optical fibers extending from the package.

Method & apparatus for packaging high frequency components

Described embodiments provide a method and apparatus for transmission of optical communications. An embodiment provides an optical transmitter which includes a control circuit to enhance the stability of output power levels, a modulator circuit with precise impedance matching for high frequency performance, and an optical coupling mechanism that relaxes the alignment tolerances between the laser and the fiber and decreases the sensitivity of the gain medium to feedback from devices coupled to the fiber. These features allow the transmitter to deliver an optical output beam which can be modulated over a wide range of frequencies, duty cycles and amplitudes with very precise definition of the rising and falling edges of the waveform. In combination these features result in an optical transmitter that may be fabricated with relatively low cost and a reduced form factor when compared with prior art optical transmitters.

Method and apparatus for optical transmission

An optical receiver may include a photodector defined on a multilayer semiconductor structure. A first electrode may be formed by at least two substantially concentric conductive rings electrically coupled to one another and to a portion of a first layer of the multilayer semiconductor structure. A second electrode may be coupled to a second layer of the multilayer semiconductor structure and configured to transfer current generated by the photodetector in response to optical emissions. A method of fabricating such an optical receiver is also disclosed.
