The quantum computer revolution is tantalizingly close

The quantum computer revolution is tantalizingly close

“When the Electronic Numerical Integrator and Computer, or Eniac, was first built by the University of Pennsylvania for the US Army in 1946, it weighed about 30 tons and had 18,000 vacuum tubes that filled an expansive room...Now, a typical laptop can do more than 3 billion calculations per second and costs around $1,000.”

Scientists use force to ‘write’ atomically-thin superconductors

Scientists use force to ‘write’ atomically-thin superconductors

A collaborative team of engineers has developed a technique that uses the tip of an atomic force microscope to “write” an atomically-thin quantum material that could enable more energy-efficient electronic and quantum devices.

Nhlanhla Mavuso: Innovating computer chips to run more efficiently

Fluid Silicon, a platform from President’s Sustainability Prize winner Nhlanhla Mavuso, allows computer chips to continuously monitor their health and self-tune as their characteristics change. The technology has the potential to reduce energy usage in data centers and improve reliability in mission-critical applications.
