New Math Makes Scientists More Certain About Quantum Uncertainties
IEEE Spectrum - February 2020

New statistical calculations suggest the fundamental quantum limits of some sensitive measurements may have been off by a factor of pi

Physicist Wojciech Górecki of the University of Warsaw in Poland addresses Heisenberg’s Uncertainty Principle and how limits in measuring some quantities up to the ultimate quantum sensitivity may be larger than expected.

Extending Quantum Entanglement Across Town
IEEE Spectrum - February 2020

Does German researchers' ability to transmit quantum bits 20 km put us on the road toward a practical quantum repeater?

In a new experiment by researchers at Ludwig Maximilian University of Munich, Germany, the distance quantum information can travel from stationary quantum memory to optical telecom pulse has been extended some twenty kilometers, serving as a milestone on the road toward a so-called quantum repeater.

Building a Quantum Computer From Off-the-Shelf Parts
IEEE Spectrum - January 2020

University of Chicago researchers develop stable and possibly scalable qubits by creating defects in commercial silicon wafers

A group of researchers at University of Chicago are pioneering a new technique for fabricating quantum bits by creating and manipulating small defects in commercially available silicon carbide wafers. The technique involves using an electron beam to create a deficiency in the wafer which behaves as a single electron spin. These electron structures can then be harnessed as possible quantum bits for quantum computation and communications.
