IBM Quantum System One is the firstcircuit-based commercialquantum computer, introduced byIBM in January 2019.[1][2][3]
This integrated quantum computing system is housed in an airtight borosilicate glass cube that maintains a controlled physical environment.[2][4] Each face of the cube is 9 feet (2.7 m) wide and tall.[2] A cylindrical protrusion from the center of the ceiling is adilution refrigerator, containing a 20-qubittransmon quantum processor.[1][5] It was tested for the first time in the summer of 2018, for two weeks, inMilan,Italy.
IBM Quantum System One was developed byIBM Research, with assistance from theMap Project Office and Universal Design Studio.CERN,ExxonMobil,Fermilab,Argonne National Laboratory, andLawrence Berkeley National Laboratory are among the clients signed up to access the system remotely.[6][7]
From April 6 to May 31, 2019, theBoston Museum of Science hosted an exhibit featuring a replica of the IBM Quantum System One.[8][9]On June 15, 2021, IBM deployed the first unit of Quantum System One inGermany at its headquarters inEhningen.[10] On April 5, 2024, IBM unveiled a Quantum System One at theRensselaer Polytechnic Institute, the first IBM quantum system on a university campus.[11]
