Uncertainty regions of observables and state-independent uncertainty relations
Lin Zhang, Shunlong Luo, Shao-Ming Fei +1
The optimal state-independent lower bounds for the sum of variances or deviations of observables are of significance for the growing number of experiments that reach the uncertaint…
Quantifying dynamical coherence with coherence measures
Sunho Kim, Chunhe Xiong, Asutosh Kumar +2
Quantum coherence, like entanglement, is a fundamental resource in quantum information. In recent years, remarkable progress has been made in formulating resource theory of coheren…
Converting coherence based on positive-operator-valued measures into entanglement
Sunho Kim, Chunhe Xiong, Asutosh Kumar +1
Quantum resource theories provide a diverse and powerful framework for extensively studying the phenomena in quantum physics. Quantum coherence, a quantum resource, is the basic in…
What are temporal correlations
Hai Wang, Ray-Kuang Lee, Manish Kumar Shukla +3
Space and time are crucial twins in physics. In quantum mechanics, spatial correlations already reveal nonclassical features, such as entanglement, and have bred many quantum techn…
Quantumness of Relative Incompatibility
Manish Kumar Shukla, Rounak Mundra, Arun K Pati +2
We propose a new measure of relative incompatibility for a quantum system with respect to two non-commuting observables, and call it quantumness of relative incompatibility. In cas…
Discrete-Time Modelling of Quantum Evolutions, the Energy-Time Uncertainty Relation and General Extensions in the Entangled History Formalism
Hai Wang, Ray-Kuang Lee, Junde Wu
Time evolution is an indivisible part in any physics theory. Usually, people are accustomed to think that the universe is a fixed background and the system itself evolves step by s…
