Charged-lepton identification at Belle~II
Belle II Collaboration, M. Abumusabh, I. Adachi +409
Effective particle identification capabilities are a strategic priority for the physics program of the Belle~II experiment. We describe the algorithms used at Belle~II for identify…

Belle, Belle II Collaborations, : +412
We search for the pionic transitions and in decays using the Belle and Belle~II data sam…
Quantum Key Distribution Without Shared Reference Frame Under Unital Noise
Junaid ur Rehman, Shehbaz Tariq, Symeon Chatzinotas
We consider a general and practical scenario of quantum key distribution (QKD) over an unknown, stationary, unital qubit channel. Furthermore, due to practical limitations, e.g., r…
Measurement of mixing-induced CP violation in the decay
Belle II Collaboration, M. Abumusabh, I. Adachi +437
Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…
Trading Quantum Ensembles
Junaid ur Rehman
We consider an example scenario where we require several copies of a pure quantum state for some quantum information processing task. Due to practical limitations, we…
QuMIMO Diversity over Discrete-Variable Free-Space Optical Channels
Shehbaz Tariq, Junaid ur Rehman, Symeon Chatzinotas
Free-space optical (FSO) links carry quantum states without fiber, but diffraction, pointing error, and atmospheric turbulence couple spatial modes and reduce end-to-end fidelity.…
