Quantum deconvolution
Cédric Bény
We propose a method for stably removing noise from measurements of a quantum many-body system. The question is cast to a linear inverse problem by using a quantum Fischer informati…
Designing Quantum Information Processing via Structural Physical Approximation
Joonwoo Bae
In quantum information processing it may be possible to have efficient computation and secure communication beyond the limitations of classical systems. In a fundamental point of v…
Distilling Entanglement with Noisy Operations
Jinho Chang, Joonwoo Bae, Younghun Kwon
Entanglement distillation is a fundamental task in quantum information processing. It not only extracts entanglement out of corrupted systems but also leads to protecting systems o…
Structure of Optimal State Discrimination in Generalized Probabilistic Theories
Joonwoo Bae, D. -G. Kim, Leong-Chuan Kwek
We consider optimal state discrimination in a general convex operational framework, so-called generalized probabilistic theories (GPTs), and present a general method of optimal dis…
Improved Measurement-Device-Independent Quantum Key Distribution with Uncharacterized Qubits
Won-Young Hwang, Hong-Yi Su, Joonwoo Bae
We propose an improved bound for the difference between phase and bit error rate in measurement-device-independent quantum key distribution with uncharacterized qubits. We show by…
Operational quasiprobabilities for continuous variables
Jeongwoo Jae, Junghee Ryu, Jinhyoung Lee
We generalize the operational quasiprobability involving sequential measurements proposed by Ryu {\em et al.} [Phys. Rev. A {\bf 88}, 052123] to a continuous-variable system. The q…
