Reinforcement Learning for Control Variational Quantum Algorithm

Sanjeev Shapkota, Yayu Mo, Chenxu Liu, Yanzhu Chen et autres

Variational quantum algorithms (VQAs) are key enablers of practical computations on near-term quantum computing hardware. However, gate-based ansatz suffer from decoherence and control errors, limiting scalability. Pulse-level approaches, such as control variational quantum eigen solver (ctrl-VQE), address these challenges by directly optimizing …

Intensity correlation technique for mode detection and information encoding with structured-light superpositions

Nazifa Rumman, Manon P. Bart, Ryan T. Glasser, Thomas A. Searles

We present an intensity-only correlation methodology for mode recognition and information encoding in turbulence-limited free-space optical links utilizing Laguerre-Gaussian (LG) modes and their superpositions. While conventional single LG modes degrade rapidly with increasing turbulence strength, petal beams formed by superposing modes with …

Distributing Polarization Entanglement Through a High-Speed Fiber-Optic Switch

Atiyya A. Davis, Brian T. Kirby, Thomas A. Searles, Daniel E. Jones

We experimentally characterize a high-speed, low-loss switch and verify that entanglement is preserved when transmitting one photon of a polarization-entangled pair through all configurations of the switch. The preservation of entanglement through the switch demonstrates the utility of the switch for quantum …
