Surveys for new computer-aided design software for cryogenic and quantum electronics

Thank you very much for taking the time to express your feedback and requirements about those.

Description of the projects

Quantum-technology computer-aided design (QTCAD):
There is currently a technological arms race to develop the first practical applications of quantum technologies with disruptive applications in sensing, communication, and computing. Such quantum technologies crucially rely on new types of hardware in which quantum bits (qubits) can be encoded and isolated from their environments to enable high-fidelity quantum operations. Despite the vital interest of quantum hardware for the development of quantum technology, the development of such hardware is hampered by the absence of appropriate computer-aided design tools.

In response to this situation, Nanoacademic Technologies is currently developing a new software product called QTCAD (Quantum-Technology Computer-Aided Design) which will serve as a design tool for quantum scientists and engineers that will significantly accelerate R&D cycles by predicting hardware performance at the design stage (before fabrication i.e., during the critical layout design phase) and giving a better understanding of device characterization results through simulations. With an initial focus on spin qubits in semiconductors, QTCAD will be released as a commercial product in May 2022.

Technology computer-aided design for cryogenic electronics (cryo-TCAD):
Cryogenic electronics – the operation of electronics devices at cryogenic temperatures – is a research topic with increasingly diverse applications in high-performance computing, space exploration, high-energy physics, and astronomy. Recently, the field has gained momentum due to the invention of cryogenic control chips (see, e.g., Intel’s Horse Ridge chip) used for scalable control of cryogenically cooled quantum computers. Despite this, commercially available technology computer-aided design (TCAD) tools (developed by, e.g., Synopsys, Silvaco, Cadence) seem to fail to deliver valuable predictions at cryogenic temperatures. In this project, we will develop new TCAD features specifically designed for cryogenic electronics, and able to predict device performance at temperatures near the absolute zero.

Description of the company:

Nanoacademic Technologies is a Montréal-based scientific software company developing atomistic and quantum modeling tools since 2008. Nanoacademic’s software is used by scientists and engineers to predict the properties of materials and devices from first principles and thus enable or accelerate R&D projects at academic, governmental, and industrial labs around the world.
