Details
Quantum technologies leveraging squeezed light have emerged as powerful tools for revolutionizing quantum communication, sensing, and computation. This talk will describe our attempts to use two-mode bright squeezed states of light for information encoding and quantum-enhanced sensing. It will explain the generation of squeezed light in the lab through the non-linear optical interaction of lasers with hot atoms, followed by a demonstration of the EPR paradox with these beams to conclusively illustrate their entanglement. The talk will then discuss how these entangled beams are crucial not only for fundamental sciences but also for encoding information by manipulating their spatial correlations. Finally, it will highlight some results in quantum-enhanced sensing, such as demonstrating a sensitivity enhancement of plasmonic sensors in transmission-based measurements. These sensors have broad applications in biological and chemical sensing and offer a unique opportunity to bring such improvements to real-life devices.
