Absolute clock synchronization with a single time-correlated photon pair source over 10km
Jianwei Lee, Lijiong Shen, Adrian Nugraha Utama +1
We demonstrate a point-to-point clock synchronization protocol based on bidirectionally propagating photons generated in a single spontaneous parametric down-conversion (SPDC) sour…
A wide-range wavelength-tunable photon-pair source for characterizing single-photon detectors
Lijiong Shen, Jianwei Lee, Antony Winata Hartanto +2
The temporal response of single-photon detectors is usually obtained by measuring their impulse response to short-pulsed laser sources. In this work, we present an alternative appr…
Quantum frequency conversion based on resonant four-wave mixing
Chin-Yao Cheng, Jia-Juan Lee, Zi-Yu Liu +2
Quantum frequency conversion (QFC), a critical technology in photonic quantum information science, requires that the quantum characteristics of the frequency-converted photon must…
A Hands-On Quantum Cryptography Workshop For Pre-University Students
Adrian Nugraha Utama, Jianwei Lee, Mathias Alexander Seidler
We developed a modified version of a conventional (BB84) quantum key distribution protocol that can be understood and implemented by students at a pre-university level. We intentio…
Asymmetric delay attack on an entanglement-based bidirectional clock synchronization protocol
Jianwei Lee, Lijiong Shen, Alessandro Cerè +3
We demonstrate an attack on a clock synchronization protocol that attempts to detect tampering of the synchronization channel using polarization-entangled photon pairs. The protoco…
Symmetrical clock synchronization with time-correlated photon pairs
Jianwei Lee, Lijiong Shen, Alessandro Cerè +3
We demonstrate a point-to-point clock synchronization protocol based on bidirectionally exchanging photons produced in spontaneous parametric down conversion (SPDC). The technique…
Multi-pulse fitting of Transition Edge Sensor signals from a near-infrared continuous-wave source
Jianwei Lee, Lijiong Shen, Alessandro Cerè +4
Transition-edge sensors (TES) are photon-number resolving calorimetric spectrometers with near unit efficiency. Their recovery time, which is on the order of microseconds, limits t…
Randomness extraction from Bell violation with continuous parametric down conversion
Lijiong Shen, Jianwei Lee, Le Phuc Thinh +8
We present a violation of the CHSH inequality without the fair sampling assumption with a continuously pumped photon pair source combined with two high efficiency superconducting d…
Interaction of light with a single atom in the strong focusing regime
Syed Abdullah Aljunid, Brenda Chng, Martin Paesold +2
We consider the near-resonant interaction between a single atom and a focused light mode, where a single atom localized at the focus of a lens can scatter a significant fraction of…
