A community portal about Quantum computers with blogs, videos, and photos. According to Wikipedia.org: A quantum computer is any device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. In a classical computer, the amount of data is measured by bits; in a quantum computer, the data is measured by qubits. The basic principle of quantum computation is that the quantum properties of particles can be used to represent and structure data, and that quantum mechanisms can be devised and built to perform operations with these data.

Way back in 2007, a company called D-Wave systems demonstrated... well, no one is really sure what it demonstrated. D-Wave claimed it was a quantum computer, but if that was so, then this tiny company managed to produce something that was way beyond anything that had been seen in a research lab, despite their large budgets and talented scientists. Since then, D-Wave has occasionally released new claims, but, most...

Researchers have built the first programmable quantum computer with 79% accuracy in results, according to a paper published in Nature. This universal quantum computer is such a device that can simulate any physical system. Unlike the Bit computing system we use today, quantum computing makes use of qubits. Qubit can be 0, 1 or a combination of 0 and 1, a state called Superposition.  These researchers have created a programmable two-qubit...

Ultracold beryllium ions tackle 160 randomly chosen programs Using a few ultracold ions, intense lasers and some electrodes, researchers have built the first programmable quantum computer. The new system, described in a paper to be published in Nature Physics, flexed its versatility by performing 160 randomly chosen processing routines. Earlier versions of quantum computers have been largely restricted to a narrow window of specific tasks. To...

Moore’s Law states that approximately every two years, the number of transistors that can be placed on an integrated circuit doubles. This has held true for the last 50 years. But there will come a point one day when physics puts a stop to that. Eventually the boundaries of atomic scale will limit transistor density. However, a new breakthrough in the field of quantum computing may provide hope for future advances. Until now, a quantum...
