Periodic Reporting for period 1 - IMMQUIRE (INTEGRATED MECHANICS FOR MODULAR QUANTUM RECONFIGURABLE CIRCUITS)
Reporting period: 2021-04-12 to 2023-04-11
The aim of IMMQUIRE is to overcome the scaling limitations of quantum technologies by developing a modular on-chip platform equipped with mechanical reconfiguration to optically interconnect and control spin qubits. This system has the potential to generate qubit entanglement on an unprecedented scale and accelerate the development of quantum computers, cryptography, and a quantum internet.
Specific objectives are a) developing a mechanically reconfigurable PIC platform designed to b) strain-tune transferred diamond spin defects into spectral alignment, and c) reconfigure PICs for spin interaction and quantum logic.

We have designed and started characterizing a SiN and a Si-based photonic chip equipped with mechanically reconfigurable components for diamond and silicon spin-photon interface respectively. We have also developed a method to integrate superconducting single-photon detectors onto arbitrary photonic platforms, including mechanically-reconfigurable platforms.
We started investigating a new type of color center in silicon with telecommunication wavelength operation, and demonstrated waveguide and cavity integration. Using the new silicon color centers, we demonstrated optical tuning of their operation wavelength. We have designed and we are in the process of fabrication and integration of devices for strain tuning of color centers in silicon and diamond.
Our chips contain designs for quantum interference from color centers, which would lead to entanglement. Testing is underway.

We are in the process of developing, for the first time, large-scale integrated photonics for spin-optic based quantum information processing. In addition, we have demonstrated the first waveguide- and cavity-coupled silicon color centers and their spectral tunability, key for quantum information processing. To complete the system, we demonstrated the integration of superconducting single-photon detectors into arbitrary photonic substrates, enabling processing-free high-quality detectors for quantum applications. These demonstrations brings us a step forward to generating qubit entanglement on a large scale for quantum computation and communication.
