Shot-based variational simulation of the toric code phase transition: Energy, global entanglement, and noise resilience
Hayede Zarei, Mohammad Hossein Zarei
We investigate the capability of variational quantum circuits in detecting a topological phase transition within the toric code model subjected to a uniform magnetic field. The det…
Layer-by-layer disentangling two-dimensional topological quantum codes
Mohammad Hossein Zarei, Mohsen Rahmani Haghighi
While local unitary transformations are used for identifying quantum states which are in the same topological class, non-local unitary transformations are also important for studyi…
Global entanglement in a topological quantum phase transition
Elahe Samimi, Mohammad Hossein Zarei, Afshin Montakhab
A useful approach to characterize and identify quantum phase transitions lies in the concept of multipartite entanglement. In this paper, we consider well-known measures of multipa…
Kosterlitz-Thouless phase and topological quantum phase
Mohammad Hossein Zarei
It has been known that encoding Boltzmann weights of a classical spin model in amplitudes of a many-body wave function can provide quantum models whose phase structure is character…
Noisy Toric code and random bond Ising model: The error threshold in a dual picture
Mohammad Hossein Zarei, Abolfazl Ramezanpour
It is known that noisy topological quantum codes are related to random bond Ising models where the order-disorder phase transition in the classical model is mapped to the error thr…
Ising order parameter and topological phase transitions: Toric code in a uniform magnetic field
Mohammad Hossein Zarei
Quantum Ising model in a transverse field is of the simplest quantum many body systems used for studying universal properties of quantum phase transitions. Interestingly, it is wel…
