M2 Student Internship

**Context**: Cryogenic data storage is essential for advancing quantum technologies, particularly in superconducting quantum electronics and computing. The challenge lies in the absence of cryogenic memory compatible with temperatures as low as 4 K. Quantum computers consist of qubits (quantum bits), a control processor, and memory. Qubits, operating at millikelvin temperatures to minimize noise interference, face connectivity issues with a room-temperature control processor. While this setup works for a few qubits, scaling to hundreds demands a different approach. Placing the control processor at the qubits' temperature, facilitated by superconducting interconnects, is crucial for scalability. However, this restricts memory options, ruling out room-temperature memories due to thermal leakage. Cryogenic 4 K memory, compatible with the superconducting control processor, solves this problem, allowing for quantum computer scalability with mínimal thermal interference. While cooling memory to 4 K is expensive, exploring slightly higher temperatures like 77 K is a cost-reducing option, albeit with a small thermal leakage drawback.

**Project**: The student will be in charge of a) Electrical characterization of the devices, DC and pulse-based programming; Programming will be carried out utilizing a LakeShore probestation equipped with a cooling system capable of reaching temperatures up to 4K. The student must undergo training to operate this system located in the FabLab at the quantum institute (IQ). The devices are programmed using WGFMU pulse generators on an Agilent B1500 device parameter analyser. The student is required to operate the machine using a testing routine created either on C or Python to establish the communication with the B1500 through a GPIB connection.

**Supervision and work environment**: Under the supervision Prof. Dominique Drouin, the work will be carried out mainly at the Interdisciplinary Institute for Technological Innovation (3IT) and at the Quantum Institute (IQ) of UdeS, in close collaboration with the company STMicroelectronics. 3IT is a unique institute in Canada, specializing in the research and development of innovative technologies for energy, electronics, robotics and health. The IQ is a state-of-the-art institute whose mission is to invent the quantum technologies of tomorrow and transfer them to the industry. The student will thus benefit from an exceptional research environment that combines students, professionals, professors and industrialists working together to develop the future technologies.
