The same ideal fidelity, 0. 9611 achieved with twelve qubits, is now attainable using a streamlined quantum circuit which markedly outperforms more complex methods under realistic conditions. This new approach employs ‘virtual’ rotations to prepare states needed for solving partial differential equations without increasing the physical complexity of the circuit itself.

Toru Fujii A new quantum circuit achieves fidelity of 0.9611 with twelve qubits in preparing smooth real-amplitude states. This single-layer approach uses Ry rotations and CZ entangling layers alongside virtual Rz frame updates to create these states; they are key components in solving partial differential equations using quantum computers. The design efficiently prepares the necessary states for tackling…
