Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could revolutionize chemistry, biology and materials science, but the development of quantum computers has been limited by the ability to increase the number of quantum bits, or qubits, that encode, store and access large amounts of data.

Step toward Quantum Computing, Spintronic Memory, Better Displays

University of Utah physicists read the subatomic “spins” in the centers or nuclei of hydrogen isotopes, and used the data to control current that powered light in a cheap, plastic LED – at room temperature and without strong magnetic fields. (more…)

Engineering defects in diamond for quantum computing and subatomic imaging

By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale sensors. They describe their technique in a paper published in the journal Applied Physics Letters, from AIP Publishing. (more…)

JILA researchers discover atomic clock can simulate quantum magnetism

Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.

Atomic clocks now join a growing list of physical systems that can be used for modeling and perhaps eventually explaining the quantum mechanical behavior of exotic materials such as high-temperature superconductors, which conduct electricity without resistance. All but the smallest, most trivial quantum systems are too complicated to simulate on classical computers, hence the interest in quantum simulators. Sharing some of the features of experimental quantum computers—a hot research topic—quantum simulators are “special purpose” devices designed to provide insight into specific challenging problems.

UCLA physicists’ technique for cooling molecules may be a stepping stone to quantum computing

The next generation of computers promises far greater power and faster processing speeds than today’s silicon-based based machines. These “quantum computers” — so called because they would harness the unique quantum mechanical properties of atomic particles — could draw their computing power from a collection of super-cooled molecules.

But chilling molecules to a fraction of a degree above absolute zero, the temperature at which they can be manipulated to store and transmit data, has proven to be a difficult challenge for scientists. (more…)
