Way back in… 2007, I co-authored an Ars report on a commercial quantum computer. In a series of articles, we revealed ourselves to be very skeptical of the D-Wave product and motivations. In the ...

In work published in Physical Review Letters researchers at Osaka University's Institute of Scientific and Industrial Research (SANKEN) used "the shortcuts to the adiabaticity (STA)" method to greatly ...

Every year, the amount of electronic data that companies process and store grows exponentially. Data centers cannot economically increase the physical space available to keep pace with the growth, and ...

The demand for advanced computing power rises year after year, but the more powerful the system, the more heat it generates. As data centers grow, they place higher demands on cooling equipment.

Add Yahoo as a preferred source to see more of our stories on Google. Have you ever been hiking and noticed that the air gets cooler as you ascend? Or mountain bike down a mountain and realize the ...

To understand adiabatic quantum computation we need to understand a little bit about how particles are described. Generally, a particle can be considered to have some potential energy and some kinetic ...

Exactly equivalent: Quantum adiabatic and quantum circuit algorithms should take the same time to run (Courtesy: iStock/Devrimb) Practical quantum computers could be one step closer thanks to ...

Thanks to Caeli Énergie, there is a new type of air conditioner that cools rooms using water evaporation, which is 5 times more eco-friendly. Caeli Énergie has introduced a new type of air conditioner ...

The range of depinning times measured is limited by a number of experimental constraints (see Supplementary Information). The lower bound is determined by the rise time of the electromagnet, which ...

Researchers achieved the acceleration of adiabatic evolution of a single spin qubit in gate-defined quantum dots. After the pulse optimization to suppress quasistatic noises, the spin flip fidelity ...
