Pintakoodien
Pintakoodien, often translated as "surface codes," represent a class of quantum error-correcting codes that are particularly well-suited for building fault-tolerant quantum computers. Unlike other quantum error correction schemes that aim to protect individual qubits, surface codes protect quantum information by encoding it across a two-dimensional lattice of physical qubits. The information is stored non-locally, meaning that no single physical qubit is essential for storing a logical qubit.
The fundamental principle behind surface codes involves measuring local "stabilizer" operators, which are combinations of physical
The performance of a surface code is typically characterized by its threshold, a parameter that represents
