Robust phase stabilization of a dark quantum channel over a 120 km deployed fiber link

March 12, 2026

Daehyun Ahn, Ivan Burenkov, Jabir Marakkarakath Vadakkepurayil, Mheni Merzouki, Paulina Kuo, Abdella Battou, Thomas Gerrits, Sergey Polyakov
We present a scalable solution for phase stabilization of dark metropolitan-scale fiber links using wavelength division multiplexing (WDM). We implement a combined feed-back and feed-forward phase stabilization for a target channel by combining error

Enabling phase stabilization of quantum networks via displacement-enhanced photon counting

April 23, 2025

Jabir Marakkarakath Vadakkepurayil, Daehyun Ahn, Ivan Burenkov, Abdella Battou, Sergey Polyakov, N. Fajar R. Annafianto
Optical phase stabilization, tracking, and locking in long fiber links are pivotal for the functionality of many communication protocols and distributed sensors. However, conventional phase stabilization methods use strong optical probe signals that may

Phase stabilization with single photon detection for quantum networks

Jabir Marakkarakath Vadakkepurayil, Daehyun Ahn, FNU Nur Fajar Rizqi Annafianto, Ivan Burenkov, Abdella Battou, Sergey Polyakov
Maintaining stable phases in interferometric systems and optical links is pivotal for the functionality of diverse quantum communication protocols. However, conventional phase stabilization methods use classical optical signals that may corrupt quantum
