How AI helps programming a quantum computer

How AI helps programming a quantum computer
2024-05-21
(Press-News.org) Generative models like diffusion models are one of the most important recent developments in Machine Learning (ML), with models as Stable Diffusion and Dall.e revolutionizing the field of image generation. These models are able to produce high quality images based on some text description. “Our new model for programming quantum computers does the same but, instead of generating images, it generates quantum circuits based on the text description of the quantum operation to be performed”, explains Gorka Muñoz-Gil from the Department of Theoretical Physics of the University of Innsbruck, Austria.

To prepare a certain quantum state or execute an algorithm on a quantum computer, one needs to find the appropriate sequence of quantum gates to perform such operations. While this is rather easy in classical computing, it is a great challenge in quantum computing, due to the particularities of the quantum world. Recently, many scientists have proposed methods to build quantum circuits with many relying machine learning methods. However, training of these ML models is often very hard due to the necessity of simulating quantum circuits as the machine learns. Diffusion models avoid such problems due to the way how they are trained. “This provides a tremendous advantage”, explains Gorka Muñoz-Gil, who developed the novel method together with Hans J. Briegel and Florian Fürrutter. “Moreover, we show that denoising diffusion models are accurate in their generation and also very flexible, allowing to generate circuits with different numbers of qubits, as well as types and numbers of quantum gates.” The models also can be tailored to prepare circuits that take into consideration the connectivity of the quantum hardware, i.e. how qubits are connected in the quantum computer. “As producing  new circuits is very cheap once the model is trained, one can use it to discover new insights about quantum operations of interest”, Gorka Muñoz-Gil names another potential of the new method.

The method developed at the University of Innsbruck produces quantum circuits based on user specifications and tailored to the features of the quantum hardware the circuit will be run on. This marks a significant step forward in unleashing the full extent of quantum computing. The work has now been published in Nature Machine Intelligence and was financially supported by the Austrian Science Fund FWF and the European Union, among others.

New research reveals that prehistoric seafloor pockmarks off the California coast are maintained by powerful sediment flows

New research reveals that prehistoric seafloor pockmarks off the California coast are maintained by powerful sediment flows
2024-05-21
New MBARI research on a field of pockmarks—large, circular depressions on the seafloor—offshore of Central California has revealed that powerful sediment flows, not methane gas eruptions, maintain these prehistoric formations. A team of researchers from MBARI, the United States Geological Survey (USGS), and Stanford University published their findings today in the Journal of Geophysical Research: Earth Surface. This work provides important information to guide decision-making about responsible use and management of the seafloor off California, including site assessments for the development of offshore wind farms. The Sur Pockmark Field—an area about the size ...

AI can help improve ER admission decisions, Mount Sinai study finds

2024-05-21
New York, NY [May 21, 2024]—Generative artificial intelligence (AI), such as GPT-4, can help predict whether an emergency room patient needs to be admitted to the hospital even with only minimal training on a limited number of records, according to investigators at the Icahn School of Medicine at Mount Sinai. Details of the research were published in the May 21 online issue of the Journal of the American Medical Informatics Association (JAMIA/DOI: 10.1093/jamia/ocae103). In the retrospective study, the researchers analyzed records from seven Mount Sinai Health System hospitals, using both structured data, such as vital signs, ...

Matcha mouthwash inhibits bacteria that causes periodontitis

2024-05-21
Highlights: Periodontitis is linked to tooth loss and other health concerns. Past studies suggest that green tea products can act against P. gingivalis, which causes periodontitis. In a new study, researchers tested matcha extract, made from green tea, against the pathogen. Lab studies suggest matcha inhibits the growth of the bacteria. A clinical trial showed that matcha mouthwash inhibited P. gingivalis populations in saliva. Washington, D.C.—Periodontitis is an inflammatory gum disease driven by bacterial infection and left untreated it can lead to complications including tooth loss. ...

Study models how ketamine’s molecular action leads to its effects on the brain

Study models how ketamine’s molecular action leads to its effects on the brain
2024-05-21
A World Health Organization Essential Medicine, ketamine is widely used at varying doses for sedation, pain control, general anesthesia and as a therapy for treatment-resistant depression. While scientists know its target in brain cells and have observed how it affects brain-wide activity, they haven’t known entirely how the two are connected. A new study by a research team spanning four Boston-area institutions uses computational modeling of previously unappreciated physiological details to fill that gap and offer new insights into how ketamine works. “This modeling work has helped decipher likely mechanisms through which ...

A diaspora-based model of human migration

A diaspora-based model of human migration
2024-05-21
How do migrants choose their destinations? Existing models, known as “gravity models,” use population size and travel distance as explanatory variables—and often fail, especially at the neighborhood scale. Many migrants prefer to move to a location near friends, family, or co-nationals. This pattern might be partly driven by factors that repeat (such as the cost of living) and partly driven by homophily, the tendency to interact with similar others. Early migrants tend to reduce uncertainty and provide information for later arrivals. Building on these observations, Rafael Prieto-Curiel and colleagues construct a migration model based on the power of the diaspora to ...

Black and Hispanic Americans experience wider temperature swings

Black and Hispanic Americans experience wider temperature swings
2024-05-21
Extreme heat can harm human health, but so can temperature extreme swings. Large daily temperature variation (DTV) has been associated with elevated mortality in studies around the world. Trees and other vegetation can lower DTV, as trees reduce temperature through transpiration during the day and also trap long-wave radiation in the atmosphere under the canopy at night, increasing temperature. But green space is not equally distributed in most cities. Shengjie Liu and Emily Smith-Greenaway examined inequality in DTV exposure in the US, using monthly nighttime and daytime land surface temperature data from satellites. ...

Gamers say they hate ‘smurfing,’ but admit they do it

2024-05-21
COLUMBUS, Ohio – Online video game players believe the behavior known as “smurfing” is generally wrong and toxic to the gaming community – but most admit to doing it and say some reasons make the behavior less blameworthy, new research finds.   The new study suggests that debates about toxicity in gaming may sometimes be more complex and nuanced than is often acknowledged, according to the researchers.   Online video games use what are called “matchmaking systems” to pair players based on skill. “Smurfing” is when players cheat these systems by creating new accounts so that they can play against people lower ...
