In this work, synthesis of robust memory modes for linear quantum passive systems in the presence of unknown inputs has been studied, aimed at facilitating secure storage and communication of quantum ...
Quantum Thermalization and Novel Phases in Non-equilibrium Quantum Systems
Quantum Thermalization Non-equilibrium Quantum Systems Novel Phases
2023/1/4
Universal quantum computers offer us the opportunities to implement novel quantum matter far away from equilibrium states. There has been remarkable progress in our understanding of the non-ergodic an...
Physicists and engineers have long been interested in creating new forms of matter, those not typically found in nature. Such materials might find use someday in, for example, novel computer chips. Be...
Affine Maps of the Polarization Vector for Quantum Systems of Arbitrary Dimension
Affine Maps the Polarization Vector Quantum Systems Arbitrary Dimension
2010/11/4
The operator-sum decomposition (OS) of a mapping from one density matrix to another has many applications in quantum information science. To this mapping there corresponds an affine map which provides...
Universal routes to spontaneous PT-symmetry breaking in non-hermitian quantum systems
Universal routes spontaneous PT-symmetry non-hermitian quantum systems
2010/11/8
PT-symmetric systems can have a real spectrum even when their Hamiltonian is non-hermitian, but develop a complex spectrum when the degree of non-hermiticity increases. Here we utilize random-matrix t...

2010/11/8
Many phenomena in physics, chemistry, and biology involve seeking an optimal control to maximize an objective for a classical or quantum system which is open and interacting with its environment. The ...
In the present paper, first the mathematical basic properties of the exceptional points are discussed. Then, their role in the description of real physical quantum systems is considered. Most interest...
We study the effects of decoherence on the entanglement generated by Unruh effect in noninertial frames by using bit flip, phase damping and depolarizing channels. It is shown that decoherence strongl...

2010/11/8
The quantum evolution of the Wigner function for Gaussian wave packets generated by a non-Hermitian Hamiltonian is investigated. In the semiclassical limit $\hbar\to 0$ this yields the non-Hermitian a...

Charge and spin transport one-dimensional quantum systems driven equilibrium
2010/4/13
We study the charge conductivity in one-dimensional prototype models of interacting particles, such as the Hubbard and the t-V spinless fermion model, when coupled to some external baths injecting and...

Ground State Entanglement Quantum Systems
2010/4/8
We examine whether it is possible for one-dimensional translationally-invariant Hamiltonians to have ground states with a high degree of entanglement. We present a family of translationally invariant ...
