Quantum sensors offer transformative performance gains over conventional technologies. However, laboratory devices are large, fragile, and expensive. This talk will cover the practical challenges of developing quantum sensors and clocks and highlight our recent work.
The future in sensor development will largely profit from adapting quantum technologies as a key enabler for pushing achievable detection limits and absolute accuracy in measurement to the ultimate limit. With the onset of the second quantum revolution, advanced quantum physics took its way out of university laboratories to research labs of tech companies, where physicists and engineers translate large tabletop quantum experiments into compact, robust and high-quality quantum measurement devices, scalable to high production volumes. The industrialization of such innovative sensing products requires both competitive price and fulfillment of size, weight, and power constraints. This enables applications ranging from magnetometers revolutionizing cardiac diagnostic to sensors allowing GPS-free navigation.
Atomic clocks are an important part of many potential quantum sensors, in addition to constituting a type of quantum sensor in their own right. For many applications, high-performance clocks must be realized in a manner compatible with operation outside of a laboratory. In this talk, I will outline efforts at developing the integrated photonics technology needed to miniaturize optical atomic clocks, including our lab’s own efforts on nonlinear nanophotonics components. I will also discuss how such integrated photonics can also impact the development of other types of quantum sensors, and present some of the challenges involved in advancing these technologies.
In this article, we present a comprehensive review of the current state of the art in quantum navigation systems, with a specific focus on their application in maritime navigation. Quantum technologies have the potential to revolutionize navigation and positioning systems due to their ability to provide highly accurate and secure information. The review covers the principles of quantum navigation and highlights the latest developments in quantum-enhanced sensors, atomic clocks, and quantum communication protocols. In this article, we also discuss the challenges and opportunities of using quantum technologies in maritime navigation, including the effects that the maritime environment and the specificity of marine applications can have on the performance of quantum sensors. Finally, this article concludes with a discussion on the future of quantum navigation systems and their potential impact on the maritime industry. This review aims at providing a valuable resource for researchers and engineers interested in the development and deployment of quantum navigation systems.
Modern developments have led to a breakthrough in quantum technology that is the key to improving navigation and positioning systems. Translation of concepts such as superposition, entanglement, and quantum interference into quantum sensors pave the way toward high precision and accuracy in measuring gravitational, magnetic, and inertial forces. This chapter provides information on the performance of quantum sensors emphasizing navigation and positioning techniques. The superior performance of quantum accelerometers, gyroscopes, and magnetometers regarding sensitivity, non-drift, and lower errors are compared to classical systems. In addition, the implementation of quantum sensors in systems that can work alone, and in systems that are incorporated with classical GPS systems but have added quantum advantages is explained. This work also discusses the current research and development efforts on quantum sensors, the challenges of integrating them into modern applications, approaches to miniaturizing the technology for practical use, and their potential future adoption in areas such as creature design, autonomous transportation, defense, and aerospace. As a result of the comprehensive content included in this chapter, readers will gain a sufficient appreciation of the scientific principles upon which quantum sensors are anchored, as well as technology’s capability and versatility in enabling accurate navigation and positioning.
