Today's quantum processors are error-prone. While the probabilities are small—less than 1 percent in many cases—each operation we perform on each qubit, including basic things like reading its ...

Company builds on recent demonstration of error-tracking in similar hardware. On Tuesday, the quantum computing startup Quera laid out a road map that will bring ...

New observations help craft guidelines for the design of near-term algorithms with expanded computational capability.

Recently, Amazon, Google, and Microsoft have announced new prototype chips, and IBM has made strides in its existing quantum road map ... the computer becomes, the more prone it is to errors.

IBM has unveiled the first quantum computer with ... its machines more error-resistant rather than larger. For years, IBM has been following a quantum-computing road map that roughly doubled ...

Palo Alto–based PsiQuantum, like Google, is also aiming to build a million-qubit quantum computer, but it has not revealed its time scale or its error-correction ... to IBM’s own road map ...

IBM has announced a series of developments to make limited but functional quantum calculations ... of classical computer simulations, provided it operates with sufficiently low errors.

And the most exciting part is that we have a road map ... IBM, Google, Microsoft, Honeywell, all the big boys are in this race to create a workable, operationally efficient quantum computer.

Although quantum ... a level of error-correction which does not exist yet. To somewhat work around these limitations, IBM has now pitched the idea of a hybrid quantum-classical computer (marketed ...

IBM has unveiled the first quantum computer with more than 1,000 qubits — the equivalent of the digital bits in an ordinary computer. But the company says it will now shift gears and focus on ...
