Topological qubits can hold quantum data for twenty seconds

Quantum computers typically struggle with extreme fragility. Their basic units of information, known as qubits, are so sensitive to heat and electromagnetic interference that they usually collapse in a fraction of a second. To solve this, researchers are developing topological qubits, which store data in the collective behavior of electrons within tiny, H-shaped devices. This method uses the mathematical properties of topology to make the information more robust against external errors.
