Control of Probe Beam Duration in Single Wavelength Monitoring of Hologram Diffraction Efficiency
This technology is a novel technique for monitoring the diffraction efficiency of Volume Holographic Elements (VHOEs) in real time. The technique works by using a shutter or chopper to periodically block one of the exposing beams during the fabrication and measuring the power of the diffracted beam using a power meter. This technique has the potential...

Heralded-Multiplexed High-Efficiency Cascaded Source of Dual-Rail Polarization-Entangled Photon Pairs using Spontaneous Parametric Down Conversion
This technology is a high-efficiency, high-fidelity method of generating pairs of polarization-entangled photonic qubits. The use of a cascaded source that performs a linear-optical entanglement swap between two spontaneous parametric down conversion (SPDC) sources, to generate a heralded photonic entangled state that has a higher fidelity compared...

Non-Gaussian Photonic State Engineering with the Quantum Frequency Processor
This technology is a means of generating non-Gaussian quantum states in light for use in quantum computing. Non-Gaussian quantum states are a subset of quantum states that enable operations that would not be possible with Gaussian states in quantum computers. As a result, they bring a lot of potential value to quantum computing. However, non-Gaussian...

Birefringent Coating to Remove Polarization Dependent Phase Shift
This technology is a method designed to remove unwanted phase shifts from optical instruments to improve their performance. The method involves the manufacture and application of a layer, or multiple layers, of birefringent materials (materials with two distinct refractive indices) such that the unwanted phase shift is removed from the optical instrument. Background: Optical...
