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…
Deciding the Attainability of the Multiparameter Quantum Fisher Information is NP-Hard
Lorcan O. Conlon, Laura Shou, V Vijendran +7
The quantum Fisher information (QFI) sets a fundamental bound on the attainable precision when estimating multiple parameters simultaneously. Incompatibility among the individually…
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…
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…
