Abstract: A quantum bit (qubit) flip chip assembly is formed when a qubit is formed on a first chip and an optically transmissive path is formed on a second chip. The two chips are bonded using solder bumps. The optically transmissive path provides optical access to the qubit on the first chip.

Abstract: Techniques relate to reading a qubit coupled to a microwave resonator. A microwave signal at a microwave resonator frequency is input to the microwave resonator that couples to the qubit. A microwave readout signal from the microwave resonator is output to a microwave to optical converter. The microwave readout signal includes a qubit state of the qubit. The microwave to optical converter is configured to convert the microwave readout signal to an optical signal. In response to the optical signal being output by the microwave to optical converter, it is determined that the qubit is in a predefined qubit state. In response to no optical signal being output by the microwave to optical converter, it is determined that the qubit is not in the predefined qubit state.

Abstract: A photo detector (10) including: a waveguide (12) of a waveguide material extending over a substrate (22), an insulating layer (26) formed over the waveguide (12) and having an opening (18) exposing the waveguide (12), a photo detector layer (16) formed over the insulating layer (26) and into the opening (18) so as to make contact with the waveguide (12), the photo detector layer 16 having a first end at the opening (18) and a second end distal from the opening (18), the photo detector layer (16) being a gradient material of the waveguide material and germanium wherein a waveguide material portion of the gradient material varies from a maximum at the first end to a minimum at the second end and wherein a germanium portion of the gradient material varies from a minimum at the first end to a maximum at the second end, a photo detector region at the second end, and a photo detector layer extension (30) extending at an angle from the photo detector layer (16) at the second end.

Abstract: Transducers and methods of making the same include a substrate having a cavity with a diameter that supports whispering gallery modes at a frequency of an input signal. A focusing structure in the cavity focuses the electric field of the input signal. A resonator directly under the focusing structure has a crystalline structure that generates an electro-optic effect when exposed to electrical fields. An electric field of the input signal modulates an output signal in the resonator via the electro-optic effect.
