Low Depth Quantum Circuits for Ising Models

Understand

A scheme for measuring complex temperature partition functions of Ising models is introduced.

• In the context of ordered qubit registers this scheme finds a natural translation in terms of global operations, and single particle measurements on the edge of the array.
• Two applications of this scheme are presented.
• First, through appropriate Wick rotations, those amplitudes can be analytically continued to yield estimates for partition functions of Ising models.
