Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons
Advanced Quantum Technologies, EarlyView.Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware
Advanced Quantum Technologies, EarlyView.Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

Some properties of the commutator of two operators
Journal of Mathematical Analysis and Applications, 1968 1. Consider a Banach space X and let B(X) be the algebra of linear- bounded operators on 3Z. If T, S, X E B(3E) we may define on B(X) the opera- tor C( T, S) X = TX - XS, which is often called the commutator of T and S. We denote px(T, S) = !E /I C(T, S)n X jjlln.

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT We review some known bounds on the eigenvalues of a matrix and use similar techniques to derive bounds for the class of nonlinear eigenproblems and, as a special case, the eigenvalues for LTI systems with delays. We present two classes of results.

Commutativity properties in Banach∗-algebras [PDF]
Pacific Journal of Mathematics, 1974 1* Introduction* Let Tlf T2, and U be bounded linear operators on a Hubert space where Tx and T2 are normal. The well-known theorem of Fuglede [13] asserts that if TtU = UT, then T?U= UT?. Putnam's generalization [13] states that if TiZ7= UT2 then T?U= UT2*.

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.

Coupled fixed point results for nonlinear integral equations
Journal of the Egyptian Mathematical Society, 2013 In this paper, we prove some coupled coincidence point theorems for such nonlinear contraction mappings having a mixed monotone property in partially ordered metric spaces by dropping the condition of commutative. We also prove coupled common fixed point

The commutation property of a stationary, axisymmetric system [PDF]
Communications in Mathematical Physics, 1970 It is shown that in studies of space-time systems which are both stationary and axisymmetric, no generality is lost by considering only cases where the stationary and axisymmetric actions (or equivalently the two corresponding Killing vector fields) commute.
