18:14 Phys.orgQuantum computer: We're planning to create one that acts like a brain

The human brain has amazing capabilities making it in many ways more powerful than the world's most advanced computers. So it's not surprising that engineers have long been trying to copy it. Today, artificial neural networks inspired by the structure of the brain are used to tackle some of the most difficult problems in artificial intelligence (AI). But this approach typically involves building software so information is processed in a similar way to the brain, rather than creating hardware that mimics neurons.

A research team led by the RIKEN Center for Emergent Matter Science (CEMS) has constructed a hybrid device for quantum computing, made from two different types of qubits, each with distinct advantages. The new system can be quickly initialized and read out, while simultaneously maintaining high control fidelity. In 1998, Daniel Loss, one of the authors of the current study, proposed, along with David DiVincenzo of IBM, to build a quantum computer by using the spins of electrons embedded in a quantum dot. The first type of qubit used for the new system — a single-spin qubit called a Loss-DiVincenzo (LD) qubit — has high control fidelity, which makes it good for calculations. It also has a long decoherence time, so that it will stay in a given state for a relatively long time before losing its signal to the environment. The downside of the LD qubit is that it cannot be

Quantum scientists working with frequency-encoded qubits have been able to perform a single operation on two qubits in parallel, but never two distinct operations, said the ORNL team. According to the researchers, coherent quantum frequency operations are challenging because it is difficult to mix frequencies arbitrarily and with low noise. “To realize universal quantum computing, you need to be able to do different operations on different qubits at the same time, and that’s what we’ve done here,” Pavel Lougovski, a research scientist, said.

An international research team has discovered a way to create qubits that emit photons at wavelengths close to those used by telecom providers. Scientists at the University of Groningen, together with colleagues from Linköping University and Norstel AB, constructed a qubit that transmits information on its status at a wavelength of 1100 nm. The researchers said it is likely that the approach they used could be tuned to wavelengths of 1300 to 1500 nm. The qubits were based on silicon carbide crystals in which molybdenum impurities created color centers that could respond to light of specific wavelengths.

When the researchers shined light at a certain wavelength onto the color centers, they found that electrons in the outer shell of the molybdenum atoms in

02:55 Yahoo ScienceWhite House issues quantum computing strategy and hosts public-private summit

Federal officials and industry leaders — including representatives from Microsoft and Alphabet, Google’s parent company — met today at a White House summit to spark new initiatives in quantum information science. Among the recommendations contained in a newly released strategic overview: setting up a U.S. Quantum Consortium, modeled after past efforts such as the non-profit, industry-led Semiconductor Research Corp.; and establishing a set of Grand Challenges to focus quantum computing research. Quantum computing stands in contrast to the world of classical computing, which is grounded in the ones and zeros of binary bits. Quantum bits, or qubits, can represent both ones… Read More

23:17 Yahoo ScienceAP Explains: The US push to boost 'quantum computing'

A race by U.S. tech companies to build a new generation of powerful "quantum computers" could get a $1.3 billion boost from Congress, fueled in part by lawmakers' fear of growing competition from China. Legislation passed earlier in September by the U.S. House of Representatives would create a 10-year federal program to accelerate research and development of the esoteric technology. As the bill moves to the Senate, where it also has bipartisan support, the White House showed its enthusiasm for the effort by holding a quantum summit Monday.

Quantum computing systems developer D-Wave Systems Inc. has published a study demonstrating a topological phase transition using its 2048-qubit annealing quantum computer. This complex quantum simulation of materials is a major step toward reducing the need for time-consuming and expensive physical research and development. This work marks an important advancement in the field and demonstrates again that the fully programmable D-Wave quantum computer can be used as an accurate simulator of quantum systems at a large scale. The methods used in this work could have broad implications in the development of novel materials, realizing Richard Feynman's original vision of a quantum simulator. "This paper represents a breakthrough in the simulation of physical systems which are otherwise essentially impossible," said J. Michael Kosterlitz, 2016 Nobel laureate. "The test reproduces most of the
