Charting Quantum Horizons: Establishing a Roadmap for Microarcsecond Astronomy

Optical interferometry has undergone a revolution in the last few years that now brings into focus the future of this rapidly developing field. In particular, achieving baselines that exceed the current limitations of a few hundred meters would push new frontiers of microarcsecond science. Such capabilities would open up an entirely new phase space of high-resolution astronomical research that could lead to breakthroughs in fields such as exoplanets, stellar physics, young stars / disks, active galactic nuclei (AGN) and supermassive black holes (SMBHs).

Roadmaps for expanding baselines by several orders of magnitude over current optical imaging arrays are now being explored, where limitations due to photon loss can be addressed by quantum-enhanced methods utilizing resources such as quantum memories and entanglement. This is the ideal time to establish collaborations between the astronomy and quantum communities to ensure this opportunity for microarcsecond science can be realized. NSF’s NOIRLab, in collaboration with the Arizona Quantum Initiative (AQuI), the Center for Quantum Networks (CQN), and the Center for High Angular Resolution Astronomy (CHARA), will be hosting an in-person one-day workshop on 11 March 2024 on establishing the roadmaps for applying quantum-enhanced methods to optical/infrared interferometry at the Graduate Tucson Hotel

After the Charting Quantum Horizons workshop, there will be the three-day Annual CHARA Science Meeting (March 12 - 14) at the same venue.

Timing: The workshop will last the whole day on Monday 11 March 2024 from 9 a.m. to about 5:00 p.m. A more detailed schedule will be coming soon.

Workshop Goal:

The goal of this one-day workshop is to establish astronomyquantum collaborations and to explore the roadmaps towards a new era of high-resolution astronomy. We aim to achieve this by accomplishing the following in the workshop:

  • Review the current state of capabilities and techniques in optical/IR interferometry
    • Highlight science cases enabled by microarcsecond resolution at optical/IR wavelengths (e.g. exoplanets, stellar physics, young stars/disks, AGN and SMBHs)
  • Discuss quantum-enhanced methods for pushing current limitations on spatial resolution
  • Establish collaborations between the astronomy and quantum communities to address science requirements and technical challenges

Another important goal following the workshop is for a collaboration of astronomers and quantum information scientists to write a joint white paper and/or publication that describes the concept of an on-sky demonstration of a quantum-enhanced telescope/interferometer.
