Portrait of Siddhant Singh, Quantum Error Correction Scientist

I build the theory that keeps quantum computers from falling apart. As a Quantum Error Correction Scientist at QuiX Quantum and a Ph.D. candidate at QuTech, TU Delft, I design fault-tolerant protocols for modular and photonic quantum architectures — the error-correcting backbone that scalable quantum computing depends on. I also run #qecArxiv, where I distill each day's quantum error correction preprints for a global research community. Away from the whiteboard, I jump out of planes with Skydive Rotterdam, train parkour and kickboxing, play 1700-rated chess, and chase light through a camera lens. The same relentlessness runs through all of it.

Academic & Professional Journey

Career Milestone
Sep 2025 - Present

Quantum Error Correction Scientist

QuiX Quantum, Enschede (Full time, Hybrid)

Designing new quantum error correction codes for photonic, measurement-based quantum computing (MBQC). I lead the development of realistic hardware-level QEC simulations that anchor the company's scalability roadmap, and build dynamic, adaptive protocols engineered to hold up under real experimental noise.

Nov 2023 - Feb 2024

Visiting Ph.D. Student

Okinawa Institute of Science and Technology (OIST), Japan

Joined the Networked Quantum Devices Unit with Prof. David Elkouss to push quantum error correction toward distributed, network-based architectures — a research visit that grew into a lasting international collaboration.

Initiative
Jul 2022 - Present

Founder & Curator - qecArxiv

qecArxiv Community

Founded and run #qecArxiv, distilling each day's quantum error correction preprints into concise summaries for a global research audience on LinkedIn and X. What started as a personal reading habit has become a daily touchstone for people tracking where the field is moving.
