Distributing Entanglement in New York City
—
Large scale quantum networks are likely to have a number of critical applications in the field of quantum information. The development of such networks requires both scalable quantum repeaters, in addition to a wide array of support hardware. In this talk, I shall introduce Qunnect’s full stack approach to realising quantum networks, based on warm-atom ensembles. In addition, I shall discuss experiments from our GothamQ testbed, where we are distributing entanglement over metropolitan fibres in New York City.

Diamond Memories and Devices for Quantum Networks
—
Quantum Networking is a nascent technology which promises to enable provably private information transfer, networked quantum computing, and enhanced quantum sensing. The core component of these networks is a quantum repeater, a device for correcting for loss and infidelities which occur when quantum information is propagated over long distances. The AWS Center for Quantum Networking (CQN) is exploring candidate systems to serve as such a repeater. One such candidate is the Silicon Vacancy (SiV) in diamond. This platform is unique in having already demonstrated memory enhanced communication and can be integrated into diamond photonic devices. In this talk, I will present recent progress made by the Center for Quantum Networking on implementing a scalable quantum repeater platform. Particular emphasis will be placed on CQN progress on the fabrication and packaging challenges that currently limit the commercialization and performance of these devices.

Quantum Sensor Networks
—
Entangling quantum sensors, such as magnetometers or interferometers, can dramatically increase their sensitivity. In this talk, we will discuss how entanglement in a network of quantum sensors can be used to accurately measure one or more properties of spatially varying fields and how to do such measurements with a minimal use of entanglement.

Entanglement-Enhanced Sensing and Data Processing
—
The 20th century has witnessed the rise of quantum mechanics and its fueled scientific and technological revolution. The humankind is now on the verge of a second quantum revolution sparked by quantum information science and engineering (QISE). Entanglement as a quintessential quantum resource lies at the heart of QISE, giving rise to a plethora of quantum-enabled or enhanced capabilities that shift the landscape of communication, sensing, and computing. In this talk, I will present our recent experimental advances in entanglement-enhanced sensing and data processing. I will first describe entangled sensor networks for precise radiofrequency [1] and optomechanical [2] sensing beyond the standard quantum limit. Building on entangled sensors, I will introduce quantum-enhanced machine learning for data classification at a physical layer [3]. Next, I will discuss a major endeavor to foster the transition from basic quantum research to near-term, widely impactful real-world quantum technologies: the construction of quantum-network testbeds as a distributed infrastructure to advance convergent QISE research and education.

Multipartite Nonlocality in Quantum Networks
—
This talk will provide an introduction to the study of quantum nonlocality in networks. The classic theory of Bell nonlocality involves local measurements performed on different parts of an entangled state. For certain entangled states, the resulting measurement correlations cannot be reproduced by a local hidden variable model and are called nonlocal correlations. The situation becomes more complex on quantum networks where multiple independent sources of entanglement can be used to generate new types of nonlocal correlations. In this talk I will describe some of the differences, challenges, and new applications that emerge when studying nonlocality on networks. Inspired by work on quantum resource theories, a "top-down" framework will be presented that differentiates different types of network correlations in terms of operational constraints on the network. Questions and discussion will be encouraged throughout the talk.

Entanglement distribution networks: Experimental state of the art and path forward
—
Often termed the age of information, the 20th century has seen fundamental shifts in technology, driven by classical information technology. We are at the cusp of the next revolution in information, this time making use of single atoms: the age of quantum information. Just as classical computer networks (“The Internet”) transformed the way we communicate and unlocked the true potential of computing technologies, quantum computer networks (“The Quantum Internet”) promise - amongst other applications - to unlock the true transformative power of quantum computers - by providing connectivity in the quantum age.
In this talk, I will present an introduction to quantum networks and discuss some of the known use-cases for such networks. Finally, I will shed light on the experimental status quo and ongoing development efforts to bring this technology outside of the lab and into our everyday lives.
