The quantum computation network includes one or more quantum processor units (QPUs) interconnected one with the other using quantum interconnects including each a quantum link and quantum network interface cards (QNICs), where each QPU is further connected to, using the QNIC, a quantum memory. The processor is configured to receive a quantum computation task, and, using a network interface card (NIC) (i) allocate the quantum computation task to the computation network, by activating any of the quantum interconnects between the QPUs according to the quantum computation task, and (ii) solve the quantum computation task using the quantum computation network.

摘要： A multi-chip module (MCM-10) includes a substrate (11), one or more photonic chips (14) disposed on the substrate, and an electronic chip (12) disposed on the substrate. The one or more photonic chips include one or more optical channels (22), which are configured to guide propagating optical signals, and two or more photonic modulator-segments (18) coupled to each of the optical channels, each photonic modulator-segment configured to modulate the propagating optical signals responsively to digitally modulated driving electrical signals provided thereto. The electronic chip is configured to generate the digitally modulated driving electrical signals on multiple different lanes (16) of the electronic chip, synchronize the driving electrical signals on the multiple lanes to a same clock, separately control respective phases of the driving electrical signals, fine-tune the voltages of the driving electrical signals on the multiple lanes, and drive the photonic modulator-segments on the photonic chips with the synchronized and phase-controlled driving electrical signals.

摘要： A photonics frequency comb generator includes two integrated dies: an indium phosphide die laser of a first wavelength is grown on from, and a silicon photonics die having a microring resonator connected to the laser and frequency modulators. The microring resonator converts the first wavelength into a number of second wavelengths. One type of the microring resonator is a hybrid non-linear optical wavelength generator, comprising non-silicon materials, such as SiC or SiGe built on silicon to yield a non-linear wavelength generation. The second wavelengths are generated by adjusting the ring's geometric size and a distance between the ring and the traverse waveguide. Another type of microring resonator splits the first wavelength into a plurality of second wavelengths and transmits the multiple second wavelengths to filters and modulators, and each selects and modulates one of the second wavelengths in a one-to-one relationship. This frequency comb generator has applications in WDM/CWDM and multi-chip modules in high speed transceivers.

摘要： A metrology system includes metrology equipment, a remote communication link, a local communication link, and a data processing unit (DPU). The metrology equipment is configured to generate a stream of data relating to inspected wafers, and to format the generated data into first and second data types. The remote communication link is configured to communicate with an external system. The data processing unit (DPU) is configured to (i) using the remote communication link, send the data belonging to the first data type directly to the external system, and (ii) perform analysis on the data belonging to the second data type, and, using the local communication link, provide results of the analysis to the metrology equipment.

摘要： A tunable vertical-cavity surface-emitting laser (VCSEL) is provided. The VCSEL includes a VCSEL emission structure, piezoelectric material, and a piezoelectric electrode. The VCSEL emission structure includes a first reflector; a second reflector; and an active cavity material structure disposed between the first and second reflectors. The active cavity material structure includes an active region. The piezoelectric material is mechanically coupled to the VCSEL emission structure such that when the piezoelectric material experiences a mechanical stress, the mechanical stress is transferred to the active cavity material structure of the VCSEL emission structure. The piezoelectric electrode is designed to cause an electric field within the piezoelectric material. The electric field causes the piezoelectric material to experience the mechanical stress, which causes the active cavity material structure to experience the mechanical stress, which causes the emission wavelength of the VCSEL to be modified from a nominal wavelength of the VCSEL.

摘要： A system comprises a transmitter including first circuitry that generates a first frame of a first type for establishing a quantum-secure link with an endpoint according to a security protocol, a data source that generates a second frame of a second type for communicating data to the endpoint, an output that couples to the endpoint via a first communication channel, and second circuitry. The second circuitry selects either the first frame or the second frame, adds information to the selected frame that identifies the selected frame as being of the first type or the second type to form an output frame, and outputs the output frame to the output.

摘要： Embodiments are disclosed for a quantum key distribution enabled intra-datacenter network. An example system includes a first vertical cavity surface emitting laser (VCSEL), a second VCSEL and a network interface controller.

摘要： A computing entity is described that obtains at least one inspection image of an at least partially fabricated product and causes the at least one inspection image to be processed by a product inspection engine. The product inspection engine includes a machine learning-trained model. The computing entity obtains an inspection result determined based on the processing of the at least one inspection image by the product inspection engine; identifies one or more training images stored in an image database based at least in part on the at least one inspection image; associates automatically generated labeling data with the one or more training images based at least in part on the inspection result determined by the processing of the at least one inspection image; and causes training of the product inspection engine using the one or more training images and the associated labeling data.
