An unambiguous quantum state discrimination for two nonorthogonal states is demonstrated using a single ion. By implementing a non‐Hermitian Hamiltonian with parity‐time‐reversal (PT) symmetry, two candidate states evolve with different speed and become orthogonal at specific time, hence can be discriminated unambiguously. Experiments are performed for

Eigenvectors of block circulant and alternating circulant matrices [PDF]
The eigenvectors and eigenvalues of block circulant matrices had been found for real symmetric matrices with symmetric submatrices, and for block circulant matrices with circulant submatrices. The eigenvectors are now found for general block circulant

Mechanism proposed for the humps in topological ferromagnet. a) Hysteresis loops of σxy in external uniaxial magnetic field Hz and b) Anomalous Hall conductivity σxy as a function of polar angle θ. Data for |h⃗|$|\vec{h}|$ = 3t and λR/t = 0.08. A, B, and C are the states of the 2D topological ferromagnets.

Benefits of Open Quantum Systems for Quantum Machine Learning
Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.

ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.

The first biometric framework to harness dynamic time warping (DTW) for single‐channel diaphragmatic surface electromyography authentication via post‐hoc alignment is presented. By optimally warping deep–normal–deep breath cycles, DTW achieves perfect genuine–impostor separation (equal error rates = 0%), while a parallel adaptive neuro‐fuzzy inference ...

The decomposition of a matrix A into a product of two or three matrices can (depending on the characteristics of those matrices) be a very useful first step in computing such things as the rank, the determinant, or an (ordinary or generalized) inverse (of A) as well as a solution to a linear system having A as its coefficient matrix.

Elliptic quantum curves of class S k $$ {\mathcal{S}}_k $$
Quantum curves arise from Seiberg-Witten curves associated to 4d N $$ \mathcal{N} $$ = 2 gauge theories by promoting coordinates to non-commutative operators.

The combination of a parity‐time symmetry wireless technology with a cholesterol sensor integrated into a smart contact lens enables high‐sensitivity cholesterol sensing at low concentration. Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease.
