A quantum computer is like an orchestra where every musician plays an invisible instrument. Instead of violins and trumpets, there are qubits — fragile particles that are easily knocked off beat by the slightest heat or noise.

An orchestra plays inside a giant refrigerator. The musicians are qubits, the elementary cells of a quantum computer. To play in harmony, they need silence: thermal noise drowns out the melody. That's why the heart of a quantum processor is cooled to nearly absolute zero — minus 273 degrees Celsius.
