Engineers in Sydney have demonstrated a quantum integrated circuit made up of just a few atoms. By precisely controlling the quantum states of the atoms, the new processor can simulate the structure ...

Researchers at IBM's T.J. Watson Research Center in Yorktown Heights, N.Y., have created the world's first logic-performing computer circuit within a single molecule. Such circuits may someday lead to ...

Quantum mechanics describes the weird behavior of microscopic particles. Using quantum systems to perform computation promises to allow researchers to solve problems in areas from chemistry to ...

Major obstacle removed for mass production of circuits ten times smaller than current mass production. As they eliminate tiny air bubbles that form when liquid droplets are molded into intricate ...

We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...

This code behaves particularly well for distributed quantum computer approaches and has wide applicability to different varieties of hardware. In the 3-D-topological code, quantum circuits look like ...
