Q-CTRL's Quantum Error Suppression and Mitigation: Improving the Performance of Quantum Computers

Saturday - December 9 2023, 08:13 UTC - 11 months ago

Q-CTRL has raised over $70 million to develop quantum error suppression and quantum error mitigation to improve the performance of quantum computers. They are working with customers to optimize shipping parcel loading and help them extract more useful answers from current quantum-computing architectures. By leveraging decades of research, they are speeding up the development of real-world quantum applications.

Q-CTRL has raised a total of over $70 million. They provide quantum error suppression and quantum error mitigation to improve the performance of quantum computers (superconducting, trapped ion, neutral atom). They leave quantum error correction to the hardware makers. They are working with customers and a shipping parcel loading optimization problem is economically useful. The number of qubits available in current systems is sufficient to provide valuable answers but we need to increase the depth of calculation by 20 times to about 6400 operations. This can likely happen by 2027. As the performance of quantum computers improve, a multitude of research, industry, and commercial applications become available. To maximize the utility from current and upcoming quantum resources, solutions for quantum noise and errors are essential. Q-CTRL approches this challenge with several products and services enabling clients to maximize their success with quantum technologies. Specifically, Q-CTRL provides a physicist-led approach to the development of quantum error-suppression and error-mitigation techniques, helping clients to maximize the performance of their hardware.

Q-CTRL’s technology is a combination of quantum-enabled algorithms and software platforms that can develop custom control solutions to capture and reduce the effect of errors from quantum hardware. In simple terms, their products are designed as safeguards for clients developing quantum-enabled technologies, including error mitigation and quantum-error suppression tools, as well as automation solutions for quantum optimization problem. Their goal is to provide reliable solutions to help preserve the integrity of quantum simulations.

Q-CTRL was founded in 2015 by a team of experienced researchers in quantum computing and control theory. The Company has 17 current industry partners in the US, Asia, and Europe, and has created bespoke algorithms for major Fortune Global 500 companies. Other strategic partners include the likes of Microsoft, Intel, Temasek, SRI International, and the US Government’s Intelligence Advanced Research Projects Activity (IARPA). Q-CTRL Founder Mike Biercuk is an ARC Laureate Fellow at University of Sydney School of Physics.

Q-CTRL’s technology is designed to extend the capabilities of existing quantum-computing architectures. By providing solutions for extracting more useful answers from the hardware, they are doing a great job in advancing the development of new products and services in the quantum computing field. Their customers cover a range of industries, from aerospace and defense to finance and logistics.

Quantum error correction is extremely challenging and requires a high degree of control over the quantum system. To account for losses of arbitrary spin flips, dephasing, entanglement errors, and other quantum errors, companies such as Q-CTRL are leveraging decades of research to speed up the development of real-world quantum applications. Q-CTRL believes that these new solutions will likely help us unlock the full power of quantum computing in the coming years.
