Semi-definite program for smooth min-entropy

The conditional min-entropy is defined as (wiki): $$ H_{\min}(A|B)_{\rho} \equiv -\inf_{\sigma_B}\inf_{\lambda}\{\lambda \in \mathbb{R}:\rho_{AB} \leq 2^{\lambda} \mathbb{I} \otimes \sigma_B\} $$ And the smooth min-entropy is defined…

Finding the violating bound of CHSH using the first level of NPA hierarchy on MATLAB

I've been trying to implement the NPA hierarchy in MATLAB using CVX library. To start off with, I thought of finding the bound of CHSH using the first level of NPA hierarchy. I represented my gram matrix as an addition of 2 matrices, One consisting…

Is there a way to map the Cu3 gate to represent a unitary matrix whose elements are complex in nature

I have this 2*2 unitary matrix one looks like U =[ -0.2840 - 0.5319i, -0.0000 - 0.7978i; -0.0000 - 0.7978i ,-0.2840 + 0.5319i] I want to represent this unitary matrix by a CU3 gate which looks like Can someone suggest a faster way to determine…

Linear and logarithmic constraint in semidefinite programming

I am trying to minimize the largest component of a vector ${\bf x} = (x_1, x_2, x_3, x_4)$, where $x_1 \ge x_2 \ge x_3 \ge x_4$, such that it satisfies a set of linear inequalities given by ${\bf A} {\bf x} \le {\bf b}$. Furthermore, I want that,…

Access IBM Q processors from MatLab

Qiskit allows a user to directly access IBM Q quantum processors (both real ones and simulator). Each user is given a personal code which is entered into source code and serves as a login to the IBM Q platform. My question is: Is there a similar…
