Deep qubits: practical quantum computers based on superconducting technologies may have to be located underground to protect against decoherence by ionizing radiation. (Courtesy: iStock/Devrimb) Such is their sensitivity to environmental noise, quantum computers might in future be shielded by thick layers of lead and even operated deep underground. So say physicists in the US, who

Several storms may develop this week, and officials are eyeing four tropical systems coming this way. There is currently one off the US coast in its southeast corner, which seems to have the highest chances of developing within the coming few days. Even if Marco and Laura have already gone, officials are still alert for coming weather events detected from the tropics. (Photo:

As corporate interest in carbon removal options grows, Puro.earth, a startup from Finland, is offering a twist on carbon marketplaces. Instead of selling and trading credits related to nature-based solutions, its exchange features industrial businesses that store carbon dioxide in products such as biochar, timber construction and other building materials. Puro.earth co-founder Antti Vihavainen said

A few weeks ago, I wrote a GreenBiz piece about what Maslow’s Hierarchy of Needs can teach us about the moment we’re in right now, based on our latest polling of Americans. At Circularity 2020, I’m talking about how to engage people in recycling, and the two ideas are linked together. The gist is that

On grid: oscillator grid states have been used to do quantum error correction in a superconducting qubit. (Courtesy: Shutterstock/Dmitriy-Rybin) A practical implementation of a quantum error correction protocol first proposed back in 2001 has been achieved by physicists in the US and France. The protocol increases the coherence time of quantum memory and although the

Plastics recycling is failing. Globally, over 350 million metric tons of plastic are produced annually, but according to the OECD, only 14-18% of that is recycled. And now that China has stopped importing the world’s plastic waste, we’re being forced to deal with it domestically.  The problem is, most plastics just aren’t recyclable. And even those
