Quantum computing still seems like it comes from the pages of a science fiction novel, but it is slowly getting closer to being a commercial reality. At CES 2019, IBM Research has made what it hopes is a big step in that direction with what it calls the “first fully-integrated commercial quantum computer,” the Q System One. Existing quantum computers are confined to R&D labs, while the Q System One includes both the electronics and cooling components needed in a single package that was developed in concert with leading industrial designers. An extraordinary amount of cooling is needed to reduce qubit errors and reduce the need for additional qubits to be used for error correction.
