The Power of Quantum Computing

Universities and computer companies like I.B.M. are making progress on quantum computers, superfast machines that obey the laws of quantum mechanics.

In 1981 the physicist Richard Feynman speculated about the possibility of "tiny computers obeying quantum mechanical laws." He suggested that such a quantum computer might be the best way to simulate real-world quantum systems, a challenge that today is largely beyond the calculating power of even the fastest supercomputers. ... Recent progress has renewed enthusiasm for finding avenues to build significantly more powerful quantum computers. Laboratory efforts in the United States and in Europe are under way using a number of technologies.

SpaceX catches Falcon Heavy nosecone with net-outfitted boat

It marks another milestone in SpaceX's long-standing effort to make spaceflight cheaper.

Technology & Innovation
  • SpaceX launched Falcon Heavy into space early Tuesday morning.
  • A part of its nosecone – known as a fairing – descended back to Earth using special parachutes.
  • A net-outfitted boat in the Atlantic Ocean successfully caught the reusable fairing, likely saving the company millions of dollars.

Politics & Current Affairs
  • A new report from a United Nation expert warns that an over-reliance on the private sector to mitigate climate change could cause a "climate apartheid."
  • The report criticizes several countries, including the U.S., for taking "short-sighted steps in the wrong direction."
  • The world's poorest populations are most vulnerable to climate change even though they generally contribute the least to global emissions.
