Extensions of the Charged Riemannian Penrose Inequality

Marcus Khuri, Gilbert Weinstein, Sumio Yamada

In this paper we investigate the extension of the charged Riemannian Penrose inequality to the case where charges are present outside the horizon. We prove a positive result when t…

Construction of Arbitrary Robust One-Qubit Operations Using Planar Geometry

Tsubasa Ichikawa, Jefferson G. Filgueiras, Masamitsu Bando +3

We show how to construct an arbitrary robust one-qubit unitary operation with a control Hamiltonian of $A_{x} (t) σ_{x} + A_{y} (t) σ_{y}$ , where $σ_{i}$ is a Pauli matrix and $A_{i} (t)$ is piec…

On integrable matrix product operators with bond dimension $D = 4$

Hosho Katsura

We construct and study a two-parameter family of matrix product operators of bond dimension $D = 4$ . The operators $M (x, y)$ act on $(C_{2})^{\otimes N}$ , i.e., the space of s…
