Open quantum system violates generalized Pauli constraints on quantum device
Communications Physics, 2023 The Pauli exclusion principle governs the fundamental structure and function of fermionic systems from molecules to materials. Nonetheless, when such a fermionic system is in a pure state, it is subject to additional restrictions known as the generalized

Tunable Non-Markovianity for Bosonic Quantum Memristors
Entropy, 2023 We studied the tunable control of the non-Markovianity of a bosonic mode due to its coupling to a set of auxiliary qubits, both embedded in a thermal reservoir. Specifically, we considered a single cavity mode coupled to auxiliary qubits described by the

Two-Unitary Decomposition Algorithm and Open Quantum System Simulation [PDF]
Quantum, 2023 Simulating general quantum processes that describe realistic interactions of quantum systems following a non-unitary evolution is challenging for conventional quantum computers that directly implement unitary gates.

Quantum error correction under numerically exact open-quantum-system dynamics
Physical Review Research, 2023 The known quantum error-correcting codes are typically built on approximative open-quantum-system models such as Born-Markov master equations. However, it is an open question how such codes perform in actual physical systems that, to some extent ...

Dissipation-induced Liouville-Majorana modes in open quantum system
Physical Review Research, 2023 In open quantum systems, topological edge states rapidly lose coherence, making them unsuitable for topological quantum computation and quantum memory.

Phase transitions in the classical simulability of open quantum systems
Scientific Reports, 2023 We introduce a Langevin unravelling of the density matrix evolution of an open quantum system over matrix product states, which we term the time-dependent variational principle-Langevin equation.

Unification of witnessing initial system-environment correlations and witnessing non-Markovianity [PDF]
, 2012 We show the connection between a witness that detects dynamical maps with initial system-environment correlations and a witness that detects non-Markovian open quantum systems.
