In a paper recently posted on arXiv, AQT describes a new 24 qubit ion trap quantum computer contained in two 19 inch room temperature racks. In collaboration with the University of Innsbruck, they produced maximally-entangled Greenberger-Horne-Zeilinger (GHZ) states with up to 24 ions without the use of post-selection or error mitigation techniques. The machine will be used by the University of Innsbruck for its own research and research collaborations with partners. However, in the near term it won’t be made publicly available for general use. AQT is developing a 50 qubit upgrade for this machine, but it isn’t expected until early 2022 per Thomas Monz, CEO of AQT. AQT previously announced a number of software partnerships and we expect that IBM’s Qiskit, Google’s Cirq, Xanadu’s Pennylane, and CQC’s t|ket> could potentially be used to program this machine. For more about this machine, you can view the arXiv paper which provides a detailed technical over of the machine. We have also included technical parameters for this machine on our premium Qubit Count and Qubit Quality pages.
