Quantum entanglement experiments hinge on two things: the optics chain, which sets the quality of the entangled state, and the single-photon detectors, which define how reliably you can measure it. This article highlights best-practice setups, proven optical stacks, and how to select detectors for different scenarios. Why optics and detectors matter Bell-state fidelity: high indistinguishability […]
Key Takeaways Long working distance microscope objectives are essential for ion-trap quantum computing, enabling precise UV laser excitation and high-resolution fluorescence imaging. Their extended working distance, wide FOV, and low distortion make them ideal for multi-ion qubit control. Avantier’s custom UV objective lens met stringent requirements for 1 µm spot projection, >80% transmission, and diffraction-limited […]
Key Takeaways In ion trapping experiments, precision optics are critical for delivering UV laser excitation and collecting ion fluorescence efficiently. This application note details the design, manufacturing process, and practical performance of a custom microscope objective for ion trapping with a long working distance (≥52 mm) and large numerical aperture (NA ≥ 0.48). The system […]
Objective Lenses for Quantum Computing Systems Objective lenses play a critical role in modern quantum computing platforms, enabling precise light delivery, efficient single-photon detection, and high-resolution imaging. Whether in neutral atom arrays, ion traps, or photonic qubit systems, these lenses are essential for system fidelity and scalability. Why Objective Lenses Are Critical in Quantum Computing […]
