Measurement disturbance and conservation laws in quantum mechanics

M. Hamed Mohammady, Takayuki Miyadera, Leon Loveridge

Measurement error and disturbance, in the presence of conservation laws, are analysed in general operational terms. We provide novel quantitative bounds demonstrating necessary con…

Geometric Bloch Vector Solution to Minimum Error Discriminations of Mixed Qubit States

Mahdi Rouhbakhsh N., Seyed Arash Ghoreishi

We investigate minimum-error (ME) discrimination for mixed qubit states using a geometric approach. By analyzing positive operator-valued measure (POVM) solutions and introducing L…

Bloch sphere analog of qudits using Heisenberg-Weyl Operators

Gautam Sharma, Sibasish Ghosh, Sk Sazim

We study an analogous Bloch sphere representation of higher-level quantum systems using the Heisenberg-Weyl operator basis. We introduce a parametrization method that will allow us…
