Quantum probe advantage in learning many-body systems
Wenzheng Dong, Andrew G. Green, Vlatko Vedral +1
The paper shows that coherently controlled quantum probes can learn properties of many‑body systems—such as fluctuations, non‑equilibrium structure, and entanglement entropy—by mea…

An unbiased measure over the matrix product state manifold
Sebastian Leontica, Andrew G. Green
Matrix product states are useful representations for a large variety of naturally occurring quantum states. Studying their typical properties is important for understanding univers…

Zero-point energy of tensor fluctuations on the MPS manifold
Sebastian Leontica, Andrew G. Green
This work presents a method for studying low-energy physics in highly correlated magnetic systems using the matrix product state (MPS) manifold. We adapt the spin-wave approach, wh…
