 Numerical and quantum simulation of a quantum disentangled liquidE. Abbasgholinejad, S. Raeisi and A. Langari Physica A: Statistical Mechanics and its Applications, 2023, vol. 615, issue C Abstract: The illustrative wave function for a quantum disentangled liquid (QDL) composed of light and heavy particles is examined within numerical simulations. Initial measurement on light particles gives rise to the volume law of the entanglement entropy of the heavy particles subsystem. The entropy reaches its maximum value as the ratio of the system to subsystem size increases. The standard deviation of entanglement entropy from its thermodynamic limit due to the initial configuration of the light particles is diminished within ensemble averaging. We have introduced a quantum circuit to simulate the underlying QDL state. The results of the quantum simulation are in agreement with the numerical simulations which confirms that the introduced circuit realizes a QDL state.
