Quantum-Limited Subdiffraction Telescopy Requires Genuine Multi-Telescope Interference
Yujie Zhang, Yunkai Wang, Wilson Wu +1
Conventional stellar interferometry reconstructs incoherent sources from pairwise mutual coherences between telescopes. Are such pairwise measurements sufficient for quantum-limite…
Probing the Critical Point (CritPt) of AI Reasoning: a Frontier Physics Research Benchmark
Minhui Zhu, Minyang Tian, Xiaocheng Yang +61
While large language models (LLMs) with reasoning capabilities are progressing rapidly on high-school math competitions and coding, can they reason effectively through complex, ope…
Temporally localized quantum operations on continuous-wave thermal light
Yunkai Wang, Yujie Zhang, Virginia O. Lorenz
Previous work showed that thermal light with a blackbody spectrum cannot be decomposed into a mixture of independent localized pulses. However, we find that in the weak-source limi…
Random Distillation Protocols in Long Baseline Telescopy
Yunkai Wang, Eric Chitambar
In quantum-enhanced astronomical imaging, multiple distant apertures work together by utilizing quantum resources distributed from a central server. Our findings suggest that pre-p…
Astronomical interferometry using continuous variable quantum teleportation
Yunkai Wang, Yujie Zhang, Virginia O. Lorenz
We propose a method to build an astronomical interferometer using continuous variable quantum teleportation to overcome the transmission loss between distant telescopes. The scheme…
Role of symmetry in quantum search via continuous-time quantum walk
Yunkai Wang, Shengjun Wu
For quantum search via the continuous-time quantum walk, the evolution of the whole system is usually limited in a small subspace. In this paper, we discuss how the symmetries of t…
Superresolution in interferometric imaging of strong thermal sources
Yunkai Wang, Yujie Zhang, Virginia O. Lorenz
Imaging using interferometer arrays based on the Van Cittert-Zernike theorem has been widely used in astronomical observation. Recently it was shown that superresolution can be ach…
