IBM Plans to Commercialize 58-Qubit Quantum Computer [tomshardware.com]

Norishige Morimoto, Director of IBM Research in Tokyo and global vice president at IBM, said that IBM intends to commercialize quantum computers [digitimes.com] within 3-5 years, when he expects quantum computers to outperform supercomputers in specific domains.

[...] The company's latest System Q One [tomshardware.com] quantum computing system has a 20-qubit quantum processor with a quantum volume of 16. Quantum volume is a quantum computing performance metric IBM believes is more accurate than just using qubits alone. Quantum volume uses a combination of the number of qubits and error rate to determine the real-world performance of a quantum processor. The company is currently giving others free and paid access to its existing quantum computers.

IBM, Google and others have said before that to achieve quantum supremacy, a quantum computer needs at least 50 qubits. Morimoto said that IBM plans to launch a next-generation 58-qubit quantum computer that can outperform supercomputers and thus are suitable for commercialization.

However, don't expect to own one of these any time soon, as they will require a working environment with a temperature of -273 degrees Celsius to protect the qubits from interference. As such, IBM believes that this sort of quantum computer will work best as a companion to classical supercomputers.

Room temperature or bust.
