Fully Quantum Perturbative Description of Correlated Stokes–Anti‐Stokes Scattering

physica status solidi (b), EarlyView.
The generation of Stokes‐anti‐Stokes (SaS) photon pairs with quantum correlations, like entanglement, has been developing recently, but a proper theoretical ground was missing. A fully quantum perturbative theory is provided to describe the four‐wave mixing contribution to the correlated SaS scattering, in which both matter and electromagnetic field ...

Analysis of the Effect of Entanglement Operators and the Scalability of Players’ Payoff Computation in N‐Player Quantum Games

Advanced Quantum Technologies, EarlyView.
A new set of entanglement operators for N‐player quantum games is introduced, and their effects on each player's behavior throughout the game are explored. The hardware efficiency of the entanglement operators is assessed against state‐of‐the‐art quantum games in terms of circuit depth and fidelity.

Making Almost Commuting Matrices Commute [PDF]

Communications in Mathematical Physics, 2009
Suppose two Hermitian matrices $A,B$ almost commute ($\Vert [A,B] \Vert \leq $). Are they close to a commuting pair of Hermitian matrices, $A',B'$, with $\Vert A-A' \Vert,\Vert B-B'\Vert \leq $? A theorem of H. Lin shows that this is uniformly true, in that for every $ >0$ there exists a $ >0$, independent of the size $N$ of the matrices ...

Entanglement in Quantum Systems Based on Directed Graphs

Advanced Quantum Technologies, EarlyView.
The entanglement properties of quantum states associated with directed graphs are investigated. It is proved that the vertex degree distribution fully determines this entanglement measure, which remains invariant under vertex relabeling, thereby highlighting its topological character.

Concept Proof of Voltage Suppression across IGBT Application for Fuse‐Current‐Limiting Hybrid DCCBs

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Abstract DC power systems require reliable and cost‐effective DC circuit breakers (DCCBs). In a previous study, we introduced a hybrid DCCB featuring a current‐limiting fuse, insulated gate bipolar transistor (IGBT), and a varistor connected in parallel.

Quantitative Two-Weight Boundedness for Iterated Commutators of Multilinear Fractional Operators With Lα,r′-Hörmander Conditions

Journal of Function Spaces
In this paper, we investigate the quantitative two-weight boundedness for iterated commutators of multilinear fractional operators with Lα,r′-Hörmander conditions. The analysis relies heavily on sparse domination techniques for the operators.

Weighted Endpoint Estimates for Commutators of Singular Integral Operators on Orlicz-Morrey Spaces

Journal of Function Spaces, 2019
In this paper, we obtain the weighted endpoint estimates for the commutators of the singular integral operators with the BMO functions and the associated maximal operators on Orlicz-Morrey Spaces.

Iterated commutators of multilinear Calderón–Zygmund maximal operators on some function spaces

Journal of Inequalities and Applications, 2019
Let T∗ $T^{*}$ be a multilinear Calderón–Zygmund maximal operator. In this paper, we study iterated commutators of T∗ $T^{*}$ and pointwise multiplication with functions in Lipschitz spaces.

On commuting and semi-commuting positive operators [PDF]

Proceedings of the American Mathematical Society, 2014
Let K K be a positive compact operator on a Banach lattice. We prove that if either [ K ⟩ [K\rangle or ⟨ K ] \langle K] is ideal irreducible, then [ K ⟩ = ⟨ K ] = L +
