FCAT and Xanadu Release Research Enabling Approximate Pattern Discovery with Quantum Computers

The Fidelity Center for Applied Technology (FCAT) and Xanadu have jointly released research detailing a new method for harnessing the power of quantum computers with imperfect, real-world data. Traditionally, quantum algorithms have struggled with the “noisy” conditions typical of most datasets, limiting their practical application. This collaboration addresses that challenge by enabling approximate pattern discovery instead of requiring precise mathematical structures. This shift allows quantum computers to identify relationships and dependencies within realistic datasets, potentially unlocking valuable applications for machine learning and data analysis. “One of the biggest challenges in applying advanced computation to real data is that the structure is never clean or exact,” said Michael Dascal, VP Quantum Technology at FCAT. Christian Weedbrook, Founder and CEO of Xanadu, added that the research “opens up a foundational quantum computing framework for new and exciting applications.”

Hidden Subgroup Problem Adaptation for Imperfect Data

Quantum computing’s potential to analyze complex data sets depends on overcoming a critical limitation. Traditional algorithms relying on the Hidden Subgroup Problem (HSP) demand pristine, highly structured data, which is rare in practical applications. Their new methods focus on identifying approximate patterns, mirroring the inherent complexities found within genuine datasets, rather than requiring exact mathematical structures. This adaptation expands the scope of quantum algorithms beyond idealized scenarios and into practical problem-solving. This approach doesn’t seek perfect matches but rather uncovers the underlying relationships and dependencies that characterize real-world information, potentially unlocking applications in areas like machine learning and data analysis. To accelerate progress, FCAT and Xanadu have released their research and associated code publicly, encouraging further development and collaboration within the quantum computing community, demonstrating a commitment to translating theoretical advancements into tangible results.

FCAT & Xanadu Collaboration Advances Practical Quantum Computing

The pursuit of practical quantum computing has long been hampered by the need for pristine data; quantum algorithms typically demand mathematically perfect inputs, a condition rarely met in real-world scenarios. This adaptation moves beyond idealized conditions, allowing quantum systems to identify approximate patterns and dependencies inherent in naturally occurring data, which is a significant step toward broader applicability. The collaboration specifically focused on enabling quantum computers to function effectively with noisy inputs, rather than requiring flawless data, thereby expanding the potential range of solvable problems. This partnership with Xanadu, a quantum hardware and software leader founded in 2016, exemplifies a commitment to translating quantum theory into tangible benefits and ultimately, real-world impact for Fidelity’s millions of customers.

We believe this work with FCAT to be a fundamental step in our goal of finding useful applications of quantum computers for machine learning.
