We introduce a fully constructive characterisation of holographic quantum error-correcting codes. That is, given a code and an erasure error we give a recipe to explicitly compute the terms in the RT formula. Using this formalism, we employ quantum circuits to construct a number of examples of ...
Vector spaces have a wide array of applications both inside and outside of math. Within mathematics, vector spaces are the fundamental setting of calculus and linear algebra. Outside of mathematics, vector spaces have applications in error-correcting codes, quantum mechanics, cryptography, Fourier tra...
In physics, the Inverse matrix is used to explore electrical circuits, quantum mechanics, and optics. These matrices are crucial in the measuring of battery power outputs and the conversion of electrical energy into other useable energy by resistors. When applying Kirchhoff’s laws of voltage and ...
One such noise source is errors in the preparation and measurement of quantum states, more commonly know as SPAM.\n","\n","If device SPAM error can be characterised, then device results can be modified to mitigate the error. Characterisation proceeds by determining overlap between different prep...
