Projectdetails

Introduction

Quantum technologies are expected to have a transformative impact by exploiting fundamental quantum mechanical effects for technological applications such as quantum computation, quantum simulation, quantum communication, and quantum sensing.

Importance of Photons

Photons are the only reliable qubit for quantum information transmission, making them an essential resource for quantum technologies. However, quantum photonics will only meet its expectation as a groundbreaking technology when integrated in a scalable fashion.

Solution: Quantum Photonic Integrated Circuits

The solution lies in quantum photonic integrated circuits where photons are used to encode and process quantum information on-chip, offering scalable quantum information processing units. Currently, different integration platforms are investigated with a selection of building blocks available.

Current Limitations

However, no platform has shown a comprehensive toolbox combining all functionalities on a single chip.

Project Goals

In this project, I will demonstrate that the thin film lithium niobate on insulator platform can simultaneously link all quantum photonics building blocks on a single platform, resulting in fully integrated quantum photonic integrated circuits.

Development of Integrated Systems

I will develop integrated Lithium Niobate Quantum systems (LiNQs) showcasing the generation, manipulation, and analysis of photonic qubits. This will result in the first compatible integration platform hosting:

  1. Semiconductor quantum emitters
  2. Quantum memories based on rare-earth ions
  3. Cryogenic electronics
  4. Superconducting single-photon detectors

Advantages of Lithium Niobate

Together with the outstanding properties of CMOS-compatible lithium niobate on insulator, such as low-loss circuits and fast modulators, these systems will provide significant advantages.

Contribution to Quantum Technology Community

By developing all required building blocks and linking them to scalable systems, I will provide the quantum technology community with a single integration platform for all quantum photonics applications.

Future Impact

LiNQs will lay the foundation for Europe's forefront position in a future photonics-driven quantum technology industry.
