Welcome
​​Dr. Siddhartha Patra
Quantum Simulation • Hybrid QPU-HPC Computing • Artificial Intelligence
​​
I am an experienced researcher with a strong foundation in theoretical condensed matter physics, quantum computing, and advanced quantum simulation tool development, with extensive experience spanning both academia and industry. I currently hold dual appointments as a Postdoctoral Researcher at the Donostia International Physics Center (DIPC) and Senior Scientist at Multiverse Computing, Spain.
​
My work specializes in quantum simulations, tensor network algorithms, hybrid quantum-classical computational methods, and tensorized neural networks for efficient Artificial Intelligence models. I have contributed to both fundamental advances—such as identifying entanglement signatures in strongly correlated systems—and practical innovations, including patent filings and high-performance simulators benchmarked against quantum processors and state of the art simulators.
