At IBM ’ s Quantum Summit in 2021 , the company issued a detailed roadmap and declared it would deliver quantum advantage on selected applications in 2023 .
Quantum advantage – demonstrating that a quantum computer can solve a real-world problem faster than a classical computer – is seen as an important step towards the scaling and eventual wider use of quantum computers .
It was a bold claim greeted with enthusiasm in some quarters , and scepticism in others . But as Richard Hopkins , Distinguished Engineer at IBM , explained to me this month , quantum isn ’ t a science project : it ’ s all aimed at delivering real-world benefits for clients .
This year promises to be an exciting one for quantum computing . IBM says it ’ s on track to deliver its 1,121-qubit Condor processor this year , while researchers at Google demonstrated in 2023 for the first time that using more qubits can lower the error rate of quantum calculations .
Could this be the year of quantum ?
