Abstract:
There is now a broad agreement that photonics is essential for reducing energy consumption of AI hardware through optical interconnects, but quantum technologies also need photonics for scaling. This is true even for “non-photonic” quantum systems based on superconductors, or trapped atoms and ions in vacuum. For example, new types of spatial light modulators and switches are needed to trap and control atoms and ions, microwave to optical quantum transducers are needed for networking superconducting processors, chip-scale laser systems are required for controlling atoms or spin qubits in solids, and very high efficiency integrated photonics is needed for quantum networks, sensors, and chip-based semiconductor quantum systems. Unfortunately, the desired level of performance and some of the functionalities are not available even in today’s best integrated photonics. We show how this can be addressed by photonics inverse design combined with emerging materials, new nanofabrication and heterogenous integration approaches. Specific examples include development of miniaturized titanium:sapphire lasers and amplifiers on chip, quantum network nodes in diamond, and a quantum simulator with silicon carbide color centers. Classical photonic technologies that will be discussed include fast, compact and error-free chip-scale optical interconnects, as well as CMOS compatible laser isolators and frequency stabilizers.
