Joint measurability of coplanar POVMs
Taro Yoshino, Koichi Tojo, Kei Hagihara +2
An unbiased qubit positive operator-valued measure (POVM) can be uniquely expressed in terms of the Bloch vector. We prove that for POVMs with coplanar Bloch vectors, they are join…

Absolute zeta functions arising from ceiling and floor Puiseux polynomials
Yoshinosuke Hirakawa, Takuki Tomita
For the -lift of a monoid scheme of finite type, Deitmar-Koyama-Kurokawa calculated its absolute zeta function by interpolating $\#X_\mathbb{Z}(\math…

The absolute Euler product representation of the absolute zeta function for a torsion free Noetherian -scheme
Takuki Tomita
The absolute zeta function for a scheme of finite type over satisfying a certain condition is defined as the limit as of the congruent zeta function for $…
