Become Entangled in this Year’s FiO + LS Quantum Theme

Image Credit: Atom interferometer, courtesy of M Squared Lasers Limited. Quantum technologies, once an imaginative vision of the future, have emerged in recent years as an essential cornerstone of optics and photonics research and investment. The 2019 OSA Frontiers in Optics and APS/DLS Laser Science (FiO + LS) conference 15 – 19 September will give special focus to the current...

“Ask Me Anything” and They Did! Top 5 Astrophysics Takeaways from Joss Bland-Hawthorn, ARC Laureate Fellow Professor of Physics and Director of the Sydney Institute for Astronomy (SIFA)

After 15 years, the first Australian-built satellites were launched from Kennedy Space Center to the International Space Station. It was a uniquely proud moment for our country and my research team at the Sydney Institute for Astronomy, University of Sydney. I was pleased to participate in this Reddit Science Ask Me Anything with The Optical Society (OSA) and share my recent experiences with...

How do you make a topologically interesting system with light?

Quantum superposition states are immensely delicate things - any interaction with the environment can cause them to decohere. This poses a significant problem for quantum computing, where information would need to be stored within quantum states for relatively long periods of time. A promising way to isolate a system exploits the topology of the system, known as 'topological protection'...

Rydberg Atoms: Two’s Company, Three’s Still Company

Once relegated to the margins of atomic physics research as basically tunable microwave antennas (albeit with enviable success), highly excited “Rydberg” atomic states have experienced a resurgence of interest in the past decade at the hands of the quantum information community, owing to their giant polarizability and long natural lifetime.  In particular, the strong long-range...

Quantum Information Goes Splat on Causality's Windshield

Physicists sleep well at night comforted in the fact that information can’t travel faster than light, but determining where exactly the causality police write the speeding ticket in various systems can be tricky to pin down.  In an invited talk at QIM 2014, my colleague Paul Lett from NIST and the Joint Quantum Institute will present new measurements showing just how this speed limit...
