Quantum probe advantage in learning many-body systems
Wenzheng Dong, Andrew G. Green, Vlatko Vedral +1
Which properties of a quantum many-body system are operationally accessible is a central question underlying spectroscopy, thermodynamics, and quantum information science. Conventi…
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…
Entanglement growth from squeezing on the MPS manifold
Sebastian Leontica, Andrew G. Green
Finding suitable characterizations of quantum chaos is a major challenge in many-body physics, with a central difficulty posed by the linearity of the Schrödinger equation. A possi…
