Quantum absorption refrigerator with trapped ions

Autor: Gleb Maslennikov, Shiqian Ding, Roland Hablützel, Jaren Gan, Alexandre Roulet, Stefan Nimmrichter, Jibo Dai, Valerio Scarani, Dzmitry Matsukevich

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

Studying quantum heat machines would extend our fundamental understanding of thermodynamics. Here, the authors report on absorption refrigeration within three normal modes of motion of a three-ion chain, studying performances using either thermal or

Quantum and classical dynamics of a three-mode absorption refrigerator

Autor: Stefan Nimmrichter, Jibo Dai, Alexandre Roulet, Valerio Scarani

Publikováno v: Quantum, Vol 1, p 37 (2017)

We study the quantum and classical evolution of a system of three harmonic modes interacting via a trilinear Hamiltonian. With the modes prepared in thermal states of different temperatures, this model describes the working principle of an absorption

Controllable generation of mixed two-photon states

Autor: Jibo Dai, Yink Loong Len, Yong Siah Teo, Leonid A Krivitsky, Berthold-Georg Englert

Publikováno v: New Journal of Physics, Vol 15, Iss 6, p 063011 (2013)

We report a controllable method for producing mixed two-photon states via spontaneous parametric down-conversion with a two-type-I crystal geometry. By using variable polarization rotators (VPRs), one obtains mixed states of various purities and degr

Secure UAV-to-Vehicle Communications

Autor: Jibo Dai, Hongjiang Lei, Gaofeng Pan, Weiwei Yang, Tingting Li, Yunfei Chen, Jia Ye

Publikováno v: IEEE Transactions on Communications. 69:5381-5393

Unmanned aerial vehicles (UAVs) communications have been widely exploited in our daily life, which leads to rising concerns about the security issue. This work investigates the secrecy performance of a UAV-to-vehicle (UAV-2-V) communication system, w

Thermodynamics is one of the oldest and well-established branches of physics that sets boundaries to what can possibly be achieved in macroscopic systems. While it started as a purely classical theory, it was realized in the early days of quantum mec

Reply to 'Comment on 'Past of a quantum particle revisited' '

Autor: Jibo Dai, Berthold-Georg Englert, Kelvin Horia, Hui Khoon Ng, Yink Loong Len

We stand by our findings in Phys. Rev A. 96, 022126 (2017). In addition to refuting the invalid objections raised by Peleg and Vaidman, we report a retrocausation problem inherent in Vaidman's definition of the past of a quantum particle.
