Wang Conducting Finite Temperature Simulation Of Non-Markovian Quantum Dynamics

Fei Wang, Assistant Professor, Chemistry and Biochemistry, received funding from the National Science Foundation for the project: "Finite temperature simulation of non-Markovian quantum dynamics in condensed phase using quantum computers."

For this research, Wang will develop efficient quantum algorithms to perform condensed phase quantum dynamics simulations on quantum computers. 

Many important physical and chemical processes occur in the condensed phase, spanning chemical reactions in solutions, charge transfer at semiconductor interfaces, and solar energy conversion in molecular aggregates. 

The scientific investigation of these processes not only promotes scientists' fundamental understanding, but also offers practical solutions to materials design and environmental sustainability. 

Wang aims to show quantum acceleration for quantum dynamics simulations in condensed phases and demonstrate practical applications of quantum computing in the area of quantum simulation. 

New advances in this project will cover unitary operator construction, efficient quantum circuit compilation, model and real system simulations, and performance comparison between different types of quantum devices. 

Wang will explore three mathematical methods (unitary dilation, singular value decomposition, and linear combinations of unitary operators) for non-unitary to unitary conversion. Wang will also assess their effectiveness based on complexity theory. 

Wang will also investigate two general approaches for circuit compilation: one that performs the exact mathematical decomposition, and another that uses the variational quantum circuit method. 

He will test the algorithm on spin-boson models as well as on realistic systems. He will also test the performance of trapped ions and compare superconducting devices. 

The success of the algorithm will offer quantum acceleration in simulations of multi-state non-Markovian quantum dynamics at finite temperature. 

A user-friendly and open-source platform will be put forward such that, with input parameters, dynamical simulations on a quantum computer can be carried out and the results analyzed. This work could potentially inspire future quantum algorithm design for simulating the dynamics of open quantum systems.

Graduate students and postdoctoral researchers involved in this project will receive rigorous training in quantum information science and master state-of-the-art quantum simulation tools. Through internship programs offered to undergraduate and high school students, Wang will support underrepresented and economically disadvantaged groups. These efforts will not only encourage broad participation in science, technology, engineering and mathematics (STEM), but also help to educate a future quantum workforce for careers in academia and industry. 

Wang will receive total funding of $505,281 from NSF for this project. Funding began in June 2023 and will end in late May 2026.

Study demonstrates efficacy of new short-term resistant TB treatment

2023-07-31
(Boston) – Tuberculosis (TB) disproportionately affects vulnerable populations including those with limited economic resources, HIV patients, those whose diet is deficient in nutrients and others. Resistant TB (MDR TB) does not respond to first line medications and is difficult to treat, requiring long regimens of 15-20 months that are associated with significant side effects and poor outcomes. Recently, new six-month regimens have been shown to have better results than the long-term treatments, with improved quality of life and health equity. But these novel regimens have not yet been adopted widely in the United States. ...

GPT-3 can reason about as well as a college student, UCLA psychologists report

2023-07-31
People solve new problems readily without any special training or practice by comparing them to familiar problems and extending the solution to the new problem. That process, known as analogical reasoning, has long been thought to be a uniquely human ability. But now people might have to make room for a new kid on the block. Research by UCLA psychologists shows that, astonishingly, the artificial intelligence language model GPT-3 performs about as well as college undergraduates when asked to solve the sort of reasoning problems that typically appear on intelligence tests and standardized tests such as the SAT. The study is published in Nature Human Behaviour. But the paper’s authors ...

When electrons slowly vanish during cooling

When electrons slowly vanish during cooling
2023-07-31
Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers at the University of Bonn and ETH Zurich have now ...

BU commentary: Including sexual and gender minority populations in medical research guarantees the health and well-being of all

2023-07-31
(Boston)—In the face of ongoing political threats to the rights and well-being of sexual and gender minority (SGM) populations, public health and health care institutions and practitioners must explicitly address the needs of marginalized populations while ensuring that those with multiple marginalized identities are well represented in research, according to a commentary in JAMA Network Open.  “If we continue to exclude SGM in research, we will remain oblivious to the troubles they face in achieving health and well-being,” said lead author Carl G. Streed, Jr., MD, MPH, FACP, ...

Luzio, who lived in São Paulo 10,000 years ago, was Amerindian like Indigenous people now, DNA reveals

Luzio, who lived in São Paulo 10,000 years ago, was Amerindian like Indigenous people now, DNA reveals
2023-07-31
An article to be published on July 31 in Nature Ecology & Evolution reveals that Luzio, the oldest human skeleton found in São Paulo state (Brazil), was a descendant of the ancestral population that settled the Americas at least 16,000 years ago and gave rise to all present-day Indigenous peoples, such as the Tupi. Based on the largest set of Brazilian archeological genomic data, the study reported in the article also offers an explanation for the disappearance of the oldest coastal communities, who built the icons of Brazilian archeology known as sambaquis, huge mounds of shells and fishbones used as dwellings, cemeteries and territorial boundaries. Archeologists often ...
