Generation of large-amplitude squeezed cat states with near-unity efficiency
Simon K. Yung, Matthew S. Winnel, Timothy C. Ralph +1
The Gottesman-Kitaev-Preskill encoding has emerged as a leading candidate for fault-tolerant quantum computation with continuous variables. For photonic architectures, the major ch…
Beating three-parameter precision trade-offs with entangling collective measurements
Simon K. Yung, Wen-Zhe Yan, Lan-Tian Feng +10
Quantum-mechanical incompatibility, which precludes the simultaneous precise measurement of non-commuting observables, imposes fundamental limits on the rate at which classical inf…
In-Line Fiber-Integrated Photon-Pair Generation from van der Waals Crystals
Mayank Joshi, Tanumoy Pramanik, Mengting Jiang +9
Miniaturized quantum light sources that operate directly in optical fibers are an attractive platform for optical quantum technologies. However, most miniaturized spontaneous param…
Precision Bounds for Characterising Quantum Measurements
Aritra Das, Simon K. Yung, Lorcan O. Conlon +6
Quantum measurements, alongside quantum states and processes, form a cornerstone of quantum information processing. However, unlike states and processes, their efficient characteri…
Saturating the Quantum Cramér--Rao Bound in Prioritised Parameter Estimation
Simon K. Yung, Aritra Das, Jun Suzuki +4
Measurement incompatibility is a cornerstone of quantum mechanics. In the context of estimating multiple parameters of a quantum system, this manifests as a fundamental trade-off b…
Generalized collective quantum tomography: algorithm design, optimization, and validation
Shuixin Xiao, Yuanlong Wang, Zhibo Hou +6
Quantum tomography is a fundamental technique for characterizing, benchmarking, and verifying quantum states and devices. It plays a crucial role in advancing quantum technologies…
All-Gaussian State Discrimination Beyond the Coherent Helstrom Bound
Angus Walsh, Lorcan Conlon, Biveen Shajilal +5
