Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Approximation Distillation of Quantum Coherence
量子相干性 近似蒸馏 相干资源理论
2023/4/18
Coherence distillation is a basic information-theoretic task in the resource theory of coherence. In this talk, I will report the framework of the approximate coherence distillation under strictly inc...
Experimental distillation of quantum nonlocality
Experimental distillation uantum nonlocality
2016/1/23
We report the first experimental demonstration of distillation of quantum nonlocality, confirming the recent theoretical protocol [Phys. Rev. Lett. 102, 120401 (2009)]. Quantum nonlocality is describe...

We have developed a cryogenic distillation system to purify Hydrogen-Deuteride (HD) gas for a polarized HD target in LEPS experiments at SPring-8. A small amount of ortho-H2 (0.01%) in the HD gas pla...
Distillation and purification of symmetric entangled Gaussian states

2010/11/8
We propose an entanglement distillation and purification scheme for symmetric two-mode entangled Gaussian states that allows to asymptotically extract a pure entangled Gaussian state from any input en...
Distillation by repeated measurements: continuous spectrum case
Distillation repeated measurements continuous spectrum case
2010/11/8
Repeated measurements on a part of a bipartite system strongly affect the other part not measured, whose dynamics is regulated by an effective contracted evolution operator. When the spectrum of this ...
General theory of assisted entanglement distillation
General theory o assisted entanglement distillation
2010/10/21
We evaluate the one-shot entanglement of assistance for an arbitrary bipartite state. This yields another interesting result, namely a characterization of the one-shot distillable entanglement of a bi...
Optimal Protocols for Nonlocality Distillation
Nonlocality Nonlocal Boxes NLBs Distillation Quantum Information
2010/10/19
Forster, Winkler, and Wolf recently showed that weak nonlocality can be amplified by giving the
first protocol that distills a class of nonlocal boxes (NLBs) [Phys. Rev. Lett. 102, 120401 (2009)].We ...
Distillation of mixed-state continuous-variable entanglement by photon subtraction
Distillation mixed-state continuous-variable entanglement photon subtraction
2010/10/21
We present a detailed theoretical analysis for the distillation of one copy of a mixed two-mode
continuous-variable entangled state using beamsplitters and coherent photon-detection techniques,includ...
Continuous variable entanglement distillation of Non-Gaussian Mixed States
Continuous variable Non-Gaussian Mixed States
2010/3/10
Many different quantum information communication protocols such as teleportation, dense coding and entanglement based quantum key distribution are based on the faithful transmission of entanglement be...
Non-locality distillation and post-quantum theories with trivial communication complexity
Non-locality distillation post-quantum theories trivial communication complexity
2010/4/9
We first present a protocol for deterministically distilling non-locality, building upon a recent result of Forster et al. [Phys. Rev. Lett. 102, 120401 (2009)]. Our protocol, which is optimal for two...
Distillation of GHZ states by selective information manipulation
Distillation GHZ states selective information manipulation
2010/10/15
Methods for distilling maximally entangled tripartite (GHZ) states from arbitrary entangled tripartite pure states are described. These techniques work for virtually any input state. Each technique ha...
