Engineered quantum systems have the potential to revolutionize sensing, communication, and computation. To realize this potential it is necessary to scale the control and connectivity of these systems without sacrificing coherence. In this webinar hosted by the Quantum Optical Science and Technology Technical Group, Sara Mouradian of the University of California, Berkeley, will discuss how integrated photonics can increase control and connectivity in quantum systems built of solid state qubits in diamond and trapped-ion qubits. Dr. Mouradian will show results on hybrid integration of diamond nodes into a SiN photonic integrated circuit to provide connectivity between individual qubits. These results are augmented by the design and fabrication of cavities from bulk diamond to enhance the collection of single photons entangled with the spin state of single qubits for mediating entanglement through the PIC.
Dr. Mouradian will then turn to trapped-ion quantum systems. All-to-all connectivity within a single trapping potential is an innate feature, but free-space routing of the lasers needed to cool and control the ions quickly becomes intractable. She will introduce an integrated photonics control platform for laser modulation and delivery, which will increase stability while simultaneously reducing size and power consumption. Finally, she will show quantum control over the rotational modes of ion crystals which could be used as detectors for orbital angular momentum modes of light for applications in quantum communication.

Who Should Attend:
Sara Mouradian received her PhD in Electrical Engineering and Computer Science in the Quantum Photonics Laboratory at MIT working on scalable integrated architectures and diamond nanophotonics for quantum information processing with nitrogen vacancy centers. Her master’s work was done in the Optical and Quantum Communications Group at MIT. There, she built the first demonstration of quantum illumination in the optical domain. She is currently an Intelligence Community Postdoctoral Fellow at the University of California, Berkeley in the Ion Trap Group, working to build useful trapped-ion quantum sensors. She is working to build robust and scalable architectures for the large-scale quantum systems that are necessary for the next generation of computing, communication, and sensing.
