Quantum algorithms for matrix operations and linear systems of equations
Wentao Qi, Alexandr I. Zenchuk, Asutosh Kumar +1
Fundamental matrix operations and solving linear systems of equations are ubiquitous in scientific investigations. Using the "Sender-Receiver" model, we propose quantum algorithms…
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…
Characterizing entanglement using quantum discord over state extensions
Chunhe Xiong, Sunho Kim, Daowen Qiu +2
We propose a framework to characterize entanglement with quantum discord, both asymmetric and symmetric, over state extensions. In particular, we show that the minimal Bures distan…
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…
