Worldwide interest in quantum technologies has grown significantly with several nations initiating multi-year, billion dollar level programs. Numerous academic, industrial and governments laboratories have expanded their programs in the quantum area and substantial progress is being realized. These efforts range from very basic research into quantum phenomena to efforts to develop devices which demonstrate the promised level of enhanced performance. At FIO, several sessions will be dedicated to examining the rapid progress recently realized in the areas of quantum computing with atoms and photons, quantum sensing for industry and fundamental physics, and in quantum communications.
Visionary Talk: Quantum Communication and Networking
LS Visionary Speaker: Prem Kumar
Machines that process quantum information are likely to be commercially available in the near future. Networking them via quantum communication to achieve a higher level of performance is a topic of current interest. In this talk I will review the current status and speculate on the future possibilities.
Visionary Talk: Quantum Technology for a Networked World
Visionary Speaker: Sir Peter Knight
I will describe the worldwide efforts to develop quantum technology, exploiting coherence and superposition. A second quantum revolution is emerging with electronic and photonic devices that use quantum science, harnessing our ability to interact with atoms, photons and electrons with exquisite level of control and with transformative potential for technology.
Session: Quantum Sensing for Industry and Fundamental Physics
A quantum sensor exploits quantum mechanical effects such as superposition and entanglement to achieve measurement sensitives and stabilities that surpass those achieved by instruments with operating principles based on classical physics. For example, by creating superpositions of matter waves using optical beam splitters, atom interferometers can be used to measure accelerations and rotations with an improved sensitivity over classical accelerometers and gyroscopes, enhancing applications from oil and gas prospecting to infrastructure monitoring. Similarly, long-lived quantum coherence in optical atomic clocks is exploited to measure time with unprecedented precision, benefitting applications ranging from the synchronization of financial markets to satellite navigation. Whilst very high measurement sensitives have been demonstrated for several classes of quantum sensor, much work is now focused on engineering portable and robust devices that will be sufficiently robust for field applications. Concurrently, these high sensitivities are also enabling explorations of new physics, ranging from searches for dark matter to testing for the time variation of fundamental constants. This session will include a broad overview of the different classes of quantum sensor, including an insight into their future prospects in industry.

Session: Quantum Computing With Atoms and Photons
Quantum computing promises to be one of the defining technological advances of this century, with future applications ranging from cyber-security and financial modelling to the simulation of new drugs and materials. Recent years have seen remarkable progress regarding the level of control over multi-qubit systems across a variety of physical platforms, with optically manipulated single atom qubits and qubits based on single photons competing closely with solid-state implementations. Whilst it is feasible that quantum computers based on these approaches will achieve ‘quantum supremacy’ in the next few years, significant challenges remain in improving the fidelity of quantum logic operations, interfacing qubit systems of differing types, and developing methods to understand and mitigate the effects of noise on quantum systems. In this session, the latest developments in quantum computing with trapped atomic ions, neutral atoms and single photons will be presented, along with a viewpoint on the development of the field of quantum computing from an industrial perspective.

Session: Quantum Communications and the Future Quantum Internet
Quantum communications represent the first commercial exploitation of quantum technologies. Using fundamental laws of quantum mechanics to guarantee secure data exchanges, quantum key distribution (QKD) is expected to be widely adopted by security critical entities such as financial institutions, healthcare organizations and government departments. Whilst the current commercially available systems based the exchange of single photons through optical fibers are limited to a range of a few hundred kilometers, a route towards truly global quantum communication is being explored by employing ground-to-satellite exchanges. Further to QKD, methods are being explored that will form the foundation of the quantum internet; a global network of quantum computing nodes with quantum communication channels linking the nodes together. These applications require the ability to create single photons on demand, faithfully transmit the quantum information stored within them over long distances and also detect the transmitted photons with high fidelity. These requirements are stimulating research into a new generation of optical components that will meet the needs of this rapidly advancing area of quantum technology. This session will provide an overview of the state of the art in quantum communications via both optical fiber and satellite links, and visions of what the quantum internet will look like and what it will be used for.
