Abstract: A photon source module includes a plurality of photon sources, wherein each photon source is configured to non-deterministically generate one or more non-entangled or entangled photons in response to receiving a trigger signal. When two or more photon sources simultaneously generate photons in response to a trigger signal, one photon of a first photon pair is directed to a photon processing system and one photon of a second photon pair is directed to a photon analyzer. During repetitive operation, the photon analyzer analyzes photons from each of the plurality of photon sources to determine characteristics of each photon source and can use that information to direct the highest quality photons to the photon processing system.

Abstract: Techniques disclosed herein relate to devices that each include one or more photonic integrated circuits and/or one or more electronic integrated circuits. In one embodiment, a device includes a silicon substrate, a die stack bonded (e.g., fusion-bonded) on the silicon substrate, and a printed circuit board (PCB) bonded on the silicon substrate, where the PCB is electrically coupled to the die stack. The die stack includes a photonic integrated circuit (PIC) that includes a photonic integrated circuit, and an electronic integrated circuit (EIC) die that includes an electronic integrated circuit, where the EIC die and the PIC die are bonded face-to-face (e.g., by fusion bonding or hybrid bonding) such that the photonic integrated circuit and the electronic integrated circuit face each other. In some embodiments, the device also includes a plurality of optical fibers coupled to the photonic integrated circuit.
