Engineering Nonclassical Light Sources

High-performance nonclassical light sources are crucial for photonic implementations of technologies for quantum-enhanced metrology, communications, and computation. Recent years have seen rapid developments in the engineering of parametric nonlinear processes to generate not only high-quality photon pairs and heralded single photons but also bright or multimode continuous-variable squeezed states. In this symposium we will hear from research groups and companies at the forefront of theory and experimental work to control the mode structure, purity, entanglement, and photon statistics of nonclassical light from parametric downconversion and four-wave mixing across platforms including bulk optics, integrated waveguides, micro-resonators, fibre, 2D material hybrids, and topological structures.
Microwave-to-optical Quantum Interconnects
Mohammad Mirhosseini, Caltech EE, USA
Alp Sipahigil, UC Berkeley EECS (as of Jan 2021), USA
The past few years have witnessed steady progress in developing quantum interconnects for microwave-to-optical conversion of photons. Qubit technologies operating at microwave frequencies, such as superconducting circuits and spin qubits, require such quantum interconnects to optical photons for realizing long-distance quantum communication and distributed quantum computing. This symposium will present latest advances and discuss challenges and opportunities ahead for integrating quantum interconnects at the system-level for quantum networking tasks.
Quantum Lidars and Super Resolution
Nisan Ozana, Harvard University, USA
Zeev Zalevsky, Bar-Ilan University, Israel
This session will focus on new and recent methods of quantum sensing. In particular, the proposed session will focus on quantum lidars, super resolution with quantum light and biomedical sensing with quantum devices. With advances in Quantum Optics during the last few years, super resolving LIDAR methods were developed via the quantum properties of a coherent beam. These methods are a breakthrough in super resolution with respect to conventional super resolution methods. Super resolution methods based on quantum properties and interactions that can lead to imaging and biomedical applications will be discussed. Furthermore, recent advances in understanding and applying quantum effects to study LIDAR and quantum imaging will be presented.
Rydberg Quantum Technologies
Na Young Kim, University of Waterloo, Canada
Kyung Soo Choi, University of Waterloo, Canada
Igor Lesanovsky, University Tubingen, Germany
This session will showcase Rydberg quantum technologies based on atoms, ions and excitons. Rydberg atoms and ions are attractive platforms for quantum information processing science and technologies as they offer strong state-dependent interactions. Recently, Rydberg excitons have been observed in bulk and two-dimensional semiconductors, offering a route towards solid-state based Rydberg quantum technologies. While Rydberg atoms/ions and Rydberg excitons possess common nature such as scaling laws of some optical properties, they also offer unique aspects. In this session, we provide a venue to examine the current status of quantum technology development and engineering applications together with the merits and challenges in their own areas. Plus, we share perspectives to collaborate between two streams towards quantum information processing science and technologies.
