007skaty Quantum Error Correction
We expand the grid and watch the errors start to fade, To shield the fragile quantum memories we made.
007skaty Error-correcting techniques like the surface code entangle physical qubits so the overall system survives local errors.
BETA
007skaty Drag shields around your qubit buddy to learn how quantum computers stay stable.
Fun Fact
Colder than space: Dilution refrigerators cool quantum chips to 0.015 Kelvin, which is about 100 times colder than the average temperature of outer space.
Glossary
quantum error correction (noun)
A set of techniques used to protect quantum information from errors caused by environmental noise and decoherence. In 1995, Peter Shor pioneered this field by designing a code that utilized nine physical qubits.
