MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611026199 A) filed by Indian Institute Of Technology, New Delhi, on March 5, for 'systems and methods for gpu-accelerated tensor network quantum circuit simulation with adaptive bond dimension management.'
Inventor(s) include Sivasubramani, Santhosh.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "A method (800) for simulating a quantum circuit on a Graphics Processing Unit (GPU) is provided. The method (800) includes decomposing a quantum statevector into a matrix product state representation to generate interconnected tensors, each having an associated bond dimension. The method (800) includes applying quantum gate operations to the tensors through tensor contraction operations on the GPU, wherein applying a two-qubit gate operation includes fusing adjacent tensor pairs and applying the operation to the fused tensor. The method (800) includes performing singular value decomposition of the fused tensor to obtain singular values, determining entanglement entropy based on the singular values, adaptively adjusting the bond dimension based on correlation between the entanglement entropy and predetermined entropy thresholds, and determining quantum measurement probabilities to generate a simulation result."
