IBM Quantum System Two is the first modular utility-scaled quantum computer system, unveiled by IBM on December 4, 2023.

It is a successor to the IBM Quantum System One.

It contains three IBM Quantum Heron processors, which can be scaled up due to its modularity, and later upgraded for newer quantum processing units, as it is upgradeable.

For its maximum efficiency, it has to be cooled to a temperature of a few hundredths of degrees above absolute zero (1020 mK), using dilution technology.
