F02.00001: Quantum Sensing with Truncated Nonlinear Interferometry Invited Speaker: Benjamin Lawrie Quantum sensors that leverage quantum noise reduction in squeezed light sources are increasingly capable of exceeding the sensitivity of state-of-the-art classical sensors. Many recent demonstrations of this class of quantum sensor have relied on intensity difference squeezing. Here, we show that phase squeezing in a truncated nonlinear interferometer enables classically inaccessible beam displacement measurements for atomic force microscopy. This approach allows us to minimize backaction noise while also operating below the photon shot noise level with reduced experimental complexity compared with intensity difference measurements. With sufficient quantum noise reduction, this approach will enable broadband atomic force microscopies that no longer require resonant operation. [Preview Abstract] |

F02.00002: Quantum enhancement of hot atoms-based optical sensors Invited Speaker: Irina Novikova Atoms are one of Nature's most sensitive probes, and atom-based clocks, magnetometers and gyroscopes can reach an unprecedented accuracy. In this talk I will discuss a several applications of room-temperature atoms for precision metrology. I will also show how the sensor performance can be improved by using non-classical light, that we can also generate using atoms. [Preview Abstract] |

F02.00003: Robust Multiphoton Quantum Technologies Invited Speaker: Omar Magana-Loaiza The emerging field of quantum photonics exploits quantum properties of light to dramatically improve the performance of protocols for metrology, and information processing. Unfortunately, the challenges involved in the preparation and characterization of photonic states with multiple particles, impose practical limitations to realistic quantum technologies. In this talk, I will report on our recent results on the preparation, manipulation and characterization of quantum states with multiple photons. I will describe how the manipulation of the quantum electromagnetic fluctuations of a pair of vacuum states leads to a novel family of nonclassical multiphoton states with tunable mean photon numbers and degrees of correlations. Our technique enables the demonstration of a quantum state of light with up tp ten photons, exhibiting nearly Poissonian statistics, that constitutes an important step towards the generation of entangled lasers . In addition, I will describe the potential of these states and photon number resolving measurements to perform quantum phase estimation. The last part of my talk will be devoted to discuss the possibility of observing exceptional points of any order in multiphoton quantum networks. [Preview Abstract] |
