Overview

Superconducting quantum computers are renowned for their exceptional computational speed, enabling them to perform intricate calculations at rates far surpassing traditional computing systems. The absence of electrical resistance in superconductors minimizes energy dissipation, resulting in remarkable energy efficiency. Operating at cryogenic temperatures, these systems mitigate environmental noise, thereby ensuring the stability of quantum states. This intrinsic stability of superconducting technology further enhances its reliability, positioning superconducting quantum computers as a cornerstone in the field of quantum computing research and development.

Quantum state control and measurement commonly rely on distinguishing between two fundamental states: 0 and 1. Qubits, which possess two energy levels, are manipulated by applying an electromagnetic field that matches the energy gap between these states, inducing oscillations in the qubits. By fine-tuning the exposure duration to this field, qubit states can be altered, and through precise control, superposition states can be achieved, where qubits simultaneously embody both states. This capability is vital for orchestrating the behavior of multiple qubits in parallel.

Superconducting qubits typically operate around 5 GHz, with microwave electromagnetic pulses used to manipulate their energy states. Rather than continuous microwave signals, brief, controlled pulses are employed to facilitate rapid quantum gates. SDT is committed to advancing superconducting quantum computing, with a goal of surpassing 100 qubits by the end of 2027, focusing on achieving unparalleled performance and long-term stability.

R&D collaboration with the Department of Physics at Korea University

Superconducting quantum computers are rapidly becoming a foundational technology, known for their high computational speed and inherent stability. As a result, global efforts to commercialize quantum computing are intensifying. However, significant technical challenges remain in achieving stable control and operation of these systems. To address these issues, Professor Yosep Kim from Korea University’s Department of Physics is collaborating with SDT to enhance the performance of superconducting quantum computers.

SDT provides specialized microwave pulse control devices tailored for superconducting quantum processors, along with the essential software needed for their operation. The software developed by SDT monitors qubits' physical properties and error rates, ensuring that quantum systems remain in optimal operational states. It automates the monitoring of qubit states and incorporates algorithms to reduce error rates while maximizing system performance, thereby improving the accuracy and reliability of quantum computers.

In addition, the quantum circuit-pulse compiler is a critical component that translates quantum gate elements—required for quantum algorithms—into pulse signals that can be executed on quantum hardware. This tool streamlines the operation of superconducting quantum computers and will become especially important as we move towards commercialization.

Finally, SDT supplies a sophisticated cryogenics system to ensure the stable and reliable operation of superconducting quantum computers, completing the infrastructure necessary for advancing the field.

SDT’s Partnership with Anyon Technologies

SDT announced plans to establish a joint venture (JV) with the global quantum computing leader Anyon Technologies in November 2024 to build a superconducting quantum computer. This JV will utilize SDT's production facilities and infrastructure to manufacture and assemble all quantum computing components with the exception of QPUs (Quantum Processing Unit), which Anyon Technologies will provide.

Since 2021, Anyon Technologies has been continuously developing various advanced quantum technologies, including high-performance superconducting quantum processors, on-chip control technologies, and microwave quantum networking architectures, demonstrating excellent scalability and performance in large-scale hybrid quantum-classical computing environments.

Anyon holds exclusive intellectual property in scalable superconducting quantum computing and is a leader in developing dilution fridges and QPUs. The company specializes in 20-qubit QPUs and has a flexible qubit architecture that can scale up to 1,000 qubits.

Through the newly established joint venture (JV), Anyon will provide its dilution fridge IP, SDT will then combine Anyon’s cutting-edge IP with its own hardware and software expertise to manage the full process of manufacturing, assembly, and installation of superconducting quantum computers.

The first product from this collaboration will be a 20-qubit system that integrates with NVIDIA's Grace Hopper Superchip, bringing together the best of both companies' technologies to offer an advanced quantum computing solution.
