Usually when the subject of the world’s most powerful computer crops up, the names of tech giants like IBM and Google comes to mind. But there is a new challenger on the block that claims that it will launch the world’s most powerful quantum computer in the coming three months. That challenger is Honeywell Quantum Solutions, a subsidiary of Honeywell International Inc., the multinational conglomerate, perhaps best known for its aerospace and defence technologies and solutions. The company thinks that the system will become the world’s most powerful computer based on the quantum computing performance measurement developed by IBM in 2017 called Quantum Volume, as per a report by Forbes.
Honeywell entered the field of quantum computing in 2018 and chose the field of trapped-ion quantum computing. The term quantum volume refers to the relative complexity of a problem that can be solved using a quantum computer and is expressed numerically. As per a report by Protocol, quantum volume “measures the overall performance of the qubits in the quantum system, combining various metrics, such as the fidelity of the qubits in the system and how conductive they are.”
Honeywell claims that its computer will have a quantum volume of at least 64 with plans of increasing it. The company’s plan is to increase the quantum volume of the computer by an order of magnitude every year for the next five years. Google’s Sycamore, claimed by the tech giant to have achieved quantum supremacy in 2019, had 53 qubits. IBM recently announced that its 28 qubit computer had a quantum volume of 32.
Some of the other companies that are working on quantum computing, as per a report by Protocol, are Microsoft, IonQ, QCI, D-Wave, Rigetti, 1QBit and Strangeworks.
