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…
Optical experiment to test negative probability in context of quantum-measurement selection
Junghee Ryu, Sunghyuk Hong, Joong-Sung Lee +6
Negative probability values have been widely employed as an indicator of the nonclassicality of quantum systems. Known as a quasiprobability distribution, they are regarded as a us…
Experimental Demonstration on Quantum Sensitivity to Available Information in Decision Making
Joong-Sung Lee, Jeongho Bang, Jinhyoung Lee +1
We present an experimental illustration on the quantum sensitivity of decision making machinery. In the decision making process, we consider the role of available information, say…
Experimental demonstration of quantum learning speed-up with classical input data
Joong-Sung Lee, Jeongho Bang, Sunghyuk Hong +4
We consider quantum-classical hybrid machine learning in which large-scale input channels remain classical and small-scale working channels process quantum operations conditioned o…
Irreducibility of coherent states
Jeongwoo Jae, Kang Hee Seol, Kwang-Geol Lee +1
We suggest an optical method which tests a nonclassical feature with a coherent state input. The test is designed with a multiplexer of on/off detectors and post-selection, adoptin…
