Scalable Generation of Multi-Photon GHZ States (QM6B.1)
Presenter: Benjamin Brecht, Paderborn University

We demonstrate the scalable generation of multi-photon GHZ states. Using multiplexing with an all-optical quantum buffer, we show an exponential increase in generation rates of four- and six-photon GHZ states compared to standard schemes.

Efficient Photon Pair Generation in Thin-film Lithium Niobate Microring Resonators (QM6B.2)
Presenter: Zhaohui Ma, Stevens Institute of Technology

We demonstrate a high purity photon pair source via parametric downcon-version in a chip-integrated lithium niobate racetrack microring resonator, observing highbrightness of 6.4 MHz mW−1GHz−1at 2350 coincidence-to-accidental ratio.

Machine Learning Assisted Quantum Photonics (QM6B.3)
Presenter: Zhaxylyk Kudyshev, Purdue

The characterization of single quantum emitters is time-consuming. We demonstrated that machine learning methods can dramatically reduce data collection time(<1s), and increase measurement accuracy of second-order fluorescence autocorrelation(>90%).

Entanglement-Assisted Quantum-Secure Covert Communication (QM6B.5)
Presenter: Michael Bullock, University of Arizona

We report that shared entanglement improves the scaling law for quantum-secure covert communication over the thermal noise lossy bosonic channel and that our entanglement-assisted optical transceiver architecture captures this improvement.

Multi-Ion Quantum Logic Driven by Integrated Optics (QM6B.6)
Presenter: Maciej Malinowski, ETH Zurich

We use trap-integrated optics to drive 2-qubit quantum gate, generating Bell-states with fidelities 99.3(2)%. Integration simultaneously brings robustness and parallelizability to trapped-ion control, of interest for large-scale quantum computing.
