“Perovskites are just a structure where you can put different atoms in… creating different physical properties,” Ernst says.
#QUANTUM ERROR CORRECTION COMPREMENTARY TRIAL#
There are, however, billions of options for the arrangement of molecules and the materials to make them, and development is currently a matter of trial and error. Improving that would make solar panels significantly more important in terms of national energy creation, particularly in northern geographies with less sunlight.Ī solution has been spotted in a crystalline structure called perovskites. However, existing panels have an efficiency rate of about 20%, with the vast majority of energy lost. Without quantum computers, they’ve been an unquestionable success, with costs falling 82% over the last decade, becoming one of the cheapest sources of energy. This includes creating higher-density batteries for lorries and grids (1.4 gigatons of CO2 emissions), decarbonising cement (1.5 gigatons), and creating anti-methane vaccines for cattle (1.1 gigatons), among other areas.
McKinsey argues that applying quantum computing to the following areas could add up to enough emissions savings to get the world back on track to net zero before 2050. What will quantum computing mean for business? “They are in the vicinity of 100 aiming for 1,000 cubits, so this is evolving.” “If you look back at the last ten years, you basically started with these two, four, five, ten cubit systems,” Ernst says. Quantum computers exist, but they’re small in scale and more qubits are needed for error correction, but progress has been made in recent years. Totted up, these five quantum-powered solutions would slash seven gigatons of carbon emissions by 2035, helping to keep the globe on track to warm by 1.5☌ – the target to avoid catastrophe.
It’s well worth the effort, argues Philipp Ernst, senior expert in the innovation practice at McKinsey, and Niko Mohr, partner at McKinsey Dusseldorf, who have identified five ways that quantum computing could be put to practical use addressing climate change. Google laid claim to reaching quantum supremacy in 2020, for instance, which means a quantum computer can solve a problem no classical computer can in a feasible length of time.
Although quantum physics-based technology is still relatively embryonic, important milestones have been reached recently.
