• Abstract: We provide a general framework which allows one to obtain the dynamics of $N$ noninteracting spatially indistinguishable particles locally coupled to separated environments. The approach is universal, being valid for both bosons and fermions and for any type of system-environment interaction. It is then applied to study the dynamics of two identical qubits under paradigmatic Markovian noises, such as phase damping, depolarizing and amplitude damping. We find that spatial indistinguishability of identical qubits is a controllable intrinsic property of the system which protects quantum entanglement against detrimental noise.

  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

  Inherent symmetry of a quantum system may protect its otherwise fragile states. We implement the one-dimensional kicked Ising model which exhibits non-local Majorana edge modes (MEMs) with $mathbbZ$ parity symmetry. MEMs are found to be resilient against certain symmetry-breaking noise owing to a prethermalization mechanism.

  Quantum memory effects can be induced even when the degrees of freedom associated to the environment are not affected at all during the system evolution. General properties of the resulting dynamics are studied with focus on the system-environment correlations, a collisional measurement-based representation, and the quantum regression hypothesis.

  We exploit the spatial correlations that are inherent in perturbations due to distant sources to reduce their impact on the visibility of interference patterns. We develop a general framework that makes use of N+1 interferometers that may differ in their masses to correct for potential environmental fields up to order N. We also show that the same ideas can be extended to the protection of entanglement between pairs of interferometers.

• Entanglement robustness via spatial deformation of identical particle wave functions [0.0]
  We take two initially separated and entangled identical qubits interacting with two independent noisy environments. After the interaction, we deform the wave functions of the two qubits to make them spatially overlap. We show that spatial indistinguishability of identical qubits can be utilized within the sLOCC operational framework to partially recover the quantum correlations spoiled by the environment.

  "hierarchical equations of motion" (HEOM) is a powerful exact numerical approach to solve the dynamics.

We present a numerical library in Python, integrated with the powerful QuTiP platform, which implements the HEOM for both bosonic and fermionic environments.
