Siddhant Singh
Quantum Error Correction Scientist at QuiX Quantum B.V. and Ph.D. Candidate at QuTech, TU Delft
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
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.
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.
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.
IBM Quantum Error Correction Summer School
IBM Research, Tarrytown, New York
Intensive training in quantum error correction fundamentals and practical implementations.
Skydiver & Community Member
Skydive Rotterdam & KNVvL (Dutch Parachute Sports)
Active skydiver and club member. Volunteering: parachute (canopy) packing, driving fellow jumpers to and from the dropzone, and helping run club social activities.
Ph.D. Candidate in Engineering Physics
QuTech, Delft University of Technology
Fault-tolerant quantum computing research supervised by Barbara Terhal (QuTech), David Elkouss (OIST), and Johannes Borregaard (Harvard).
Focus: quantum error correction, fault-tolerance thresholds, and modular, network-based quantum architectures.
Junior Researcher - Quantum Algorithms
BosonQ Psi Pvt. Ltd., India
Quantum algorithms development with focus on encoding of fluid-dynamics problems and error reduction methodologies.
Research Assistant
RIKEN, Theoretical Quantum Physics Lab, Japan
Research under Chief Scientist Prof. Franco Nori. Contributed to theoretical quantum physics research.
