Abstract: An example integrated generalized Mach-Zehnder Interferometer (GMZI) to process a quantum state of light is described. A quantum state of light comprising one or more photons can be received by a first coupler network in the GMZI. Using the first coupler network, the quantum state of light is distributed to one or more of a plurality of waveguide arms in the GMZI. The phase of the quantum state of light is adjusted using a plurality of phase shifters in the GMZI. The phase is adjusted for portions of the quantum state of light in one of the plurality of waveguide arms. The phase-adjusted quantum light is received by a second coupler network in the GMZI. Using the second coupler network, the quantum state of light is combined onto one or more outputs of the waveguide arms. The combined quantum light is outputted.

Abstract: A waveguide structure includes a substrate and a waveguide core coupled to the substrate and including a first material characterized by a first index of refraction and a first electro-optic coefficient. The waveguide structure also includes a first cladding layer at least partially surrounding the waveguide core and including a second material characterized by a second index of refraction less than the first index of refraction and a second electro-optic coefficient greater than the first electro-optic coefficient. The second cladding layer is coupled to the first cladding layer.

Abstract: A device includes photon detectors, first photonic modes (coupled with photons sources) for outputting a first set of four photons, second photonic modes to provide a second set of at least four photons to the photon detectors, third photonic modes (coupled with the photon sources) to provide a third set of at least photons to the photon detectors, first couplers coupling modes in the first set of photonic modes to modes in the second set of photonic modes, and second couplers coupling modes of the third set of photonic modes to modes of the second set of photonic modes. The first and second couplers are configured to cause the first photonic modes to output, with a first non-zero probability, a pair of photons in a Bell state when a first number of photons is provided to respective inputs of the first photonic modes and the third photonic modes.

Abstract: An electro-optical device is fabricated on a semiconductor-on-insulator (SOI) substrate. The electro-optical device comprises a silicon dioxide layer, and an active layer having ferroelectric properties on the silicon dioxide layer. The silicon dioxide layer includes a first silicon dioxide layer of the SOI substrate and a second silicon dioxide layer converted from a silicon layer of the SOI substrate. The active layer includes a buffer layer epitaxially grown on the silicon layer of the SOI substrate and a ferroelectric layer epitaxially grown on the buffer layer. The electro-optical device further comprises one or more additional layers over the active layer, and first and second contacts to the active layer through at least one of the one or more additional layers. Methods of fabricating the electro-optical device are also described herein.

Abstract: Circuits and methods that implement multiplexing for photons propagating in waveguides (or optical paths) are disclosed, in which an input photon received on a selected one of a set of input paths can be selectably routed to one or more of a set of output paths. One or more of the output paths can be always selected while one or more other output paths can be selected on a rotating or cyclic basis, in a fixed order, and the input path can be selected based at least in part on which one(s) of a set of input paths is (are) currently propagating a photon.

Abstract: A fault-tolerant quantum computer using topological codes such as surface codes can have an architecture that reduces the amount of idle volume generated. The architecture can include qubit modules that generate surface code patches for different qubits and a network of interconnections between different qubit modules. The interconnections can include “port” connections that selectably enable coupling of boundaries of surface code patches generated in different qubit modules and/or “quickswap” connections that selectably enable transferring the state of a surface code patch from one qubit module to another. Port and/or quickswap connections can be made between a subset of qubit modules. For instance port connections can connect a given qubit module to other qubit modules within a fixed range. Quickswap connections can provide a log-tree network of direct connections between qubit modules.

Abstract: An assembly system for assembling an optical die to an optical substrate includes test equipment configured to test optical couplers formed between the optical die and the optical substrate. The assembly system is configured to adjust an alignment of the optical die relative to the optical substrate until the optical couplers meet a performance metric. After the performance metric is met the optical die is permanently attached to the optical substrate.
