  • Patent number: 11955778
    Abstract: A method and system for large scale Vertical-Cavity Surface-Emitting Laser (VCSEL) binning from wafers to be compatible with a Clock-Data Recovery Unit (CDRU) and/or a VCSEL driver are provided. An illustrative method of binning is provided that includes: for at least a portion of VCSELs on a wafer, measuring a set of representative parameters of the VCSELs, of predetermined DC or small-signal values, and sorting the measured VCSELs into clusters according to the measured set of representative parameters of the VCSELs; further sorting the clusters into sub-groups that comply with specifications of the VCSEL driver; and providing a feedback signal to the CDRU for equalizing control signals provided to the VCSEL driver.

  • Patent number: 11949463
    Abstract: Various embodiments of the present disclosure are directed to accessing a quantum communication channel undetected and/or characterizing this communication channel based upon attempted access. An example method includes accessing a quantum communication channel transmitting one or more qubits. The method includes the introduction of a noise signal to the quantum communication channel and then applying in its absence one or more weak or variable-strength measurements to the quantum communication channel. A strength of at least one measurement of the one or more measurements is based at least in part upon the current noise signal. The method further includes obtaining information associated with the one or more qubits based on the one or more measurements.

  • Publication number: 20240089092
    Abstract: Embodiments are disclosed for providing quantum-classical hybrid security. An example system includes a hybrid quantum-classical transmitter device. The hybrid quantum-classical transmitter device includes a classical transmitter and a quantum transmitter. The classical transmitter is configured to generate data based on a cryptography technique. The classical transmitter is also configured to generate a classical bitstream representation of the data, where the classical bitstream is configured for transmission via an optical communication channel. The quantum transmitter is configured to embed one or more qubits into the classical bitstream to generate a hybrid quantum-classical bitstream for transmission via the optical communication channel.

  • Publication number: 20240039711
    Abstract: Bi-directional quantum interconnects are provided that include a first communication module and a second communication module. The first communication module includes a first quantum transmitter and a first quantum receiver, and the second communication module includes a second quantum transmitter and a second quantum receiver. The example interconnect further includes a first communication medium communicably coupling the first communication module and the second communication module such that communication is provided between the first quantum transmitter and the second quantum receiver and between the second quantum transmitter and the first quantum receiver via the first communication medium. The first quantum transmitter and the second quantum transmitter generate qubits having first and second quantum characteristics, respectively, to allow for bi-directional quantum communication over a common channel.

  • Publication number: 20220239056
    Abstract: A method and system for analyzing Vertical-Cavity Surface-Emitting Lasers (VCSELs) on a wafer are provided. An illustrative method of is provided that includes: applying a stimulus to each of the plurality of VCSELs on the wafer; measuring, for each of the plurality of VCSELs, two or more VCSEL parameters responsive to the stimulus; correlating the measured two or more VCSEL parameters to define a value of a common performance characteristic; and identifying clusters of VCSELs having similar values of the common performance characteristic. The clusters of VCSELs may be determined to collectively meet or not meet an optical performance requirement defined for the VCSELs on the wafer.
