Contextual quantum metrology
Jeongwoo Jae, Jiwon Lee, M. S. Kim +2
Quantum metrology promises higher precision measurements than classical methods. Entanglement has been identified as one of quantum resources to enhance metrological precision. How…
Metrological power of incompatible measurements
Jeongwoo Jae, Jiwon Lee, Kwang-Geol Lee +2
We show that measurement incompatibility is a necessary resource to enhance the precision of quantum metrology. To utilize incompatible measurements, we propose a probabilistic met…
Quantum steering of multimode Gaussian states by Gaussian measurements: monogamy relations and the Peres conjecture
Se-Wan Ji, M. S. Kim, Hyunchul Nha
It is a topic of fundamental and practical importance how a quantum correlated state can be reliably distributed through a noisy channel for quantum information processing. The con…
Efficient entanglement criteria beyond Gaussian limits using Gaussian measurements
Hyunchul Nha, Su-Yong Lee, Se-Wan Ji +1
We present a formalism to derive entanglement criteria beyond the Gaussian regime that can be readily tested by only homodyne detection. The measured observable is the Einstein-Pod…
