CU researchers probe ‘astonishing qualities’ of honeycomb-like quantum material
A series of buzzing, bee-like “loop-currents” could explain a recently discovered, never-before-seen phenomenon in a type of quantum material. The findings from researchers at the אוניברסיטת קולורדו בולדר may one day help engineers develop new kinds of devices, such as quantum sensors or the quantum equivalent of computer memory storage devices.
The quantum material in question is known by the chemical formula Mn3Si2Te6. But you could also call it “honeycomb” because its manganese and tellurium atoms form a network of interlocking octahedra that look like the cells in a beehive.
Physicist Gang Cao and his colleagues at CU Boulder synthesized this molecular beehive in their lab in 2020, and they were in for a surprise: Under most circumstances, the material behaved a lot like an insulator. In other words, it did not allow electric currents to pass through it easily. When they exposed the honeycomb to magnetic fields in a certain way, however, it suddenly became millions of times less resistant to currents. It was almost as if the material had morphed from rubber into metal.
The group reports that, under certain conditions, the honeycomb is abuzz with tiny internal currents known as chiral orbital currents, or loop currents. Electrons zip around in loops within each of the octahedra in this quantum material. Since the 1990s, physicists have theorized such loop currents could exist in a handful of known materials, such as high-temperature superconductors, but they have yet to directly observe them.
Cao said they could be capable of driving startling transformations in quantum materials like the one he and his team stumbled on.
“We’ve discovered a new quantum state of matter,” Cao said. “Its quantum transition is almost like ice melting into water.” Click here to read original, lengthy article on CU website

Breakthrough: Qubits for a programmable, solid-state superconducting processor
Researchers from Arizona State University and Zhejiang University in China, along with two theorists from the United Kingdom.have been able to demonstrate for the first time that large numbers of quantum bits, or qubits, can be tuned to interact with each other while maintaining coherence for an unprecedentedly long time, in a programmable, solid-state superconducting processor. Quantum News Briefs summarizes the announcement from Physics News.
In a new paper, scientists demonstrated a “first look” at the emergence of quantum many-body scarring (QMBS) states as a robust mechanism for maintaining coherence among interacting qubits. Such exotic quantum states offer the appealing possibility of realizing extensive multipartite entanglement for a variety of applications in quantum information science and technology to achieve high processing speed and low power consumption. The paper, which will be published today (October 13) in the journal פיזיקת טבע
” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>Nature Physics, is authored by ASU Regents Professor Ying-Cheng Lai, his former ASU doctoral student Lei Ying and experimentalist Haohua Wang, both professors at Zhejiang University in China.
"למדינות QMBS יש את היכולת המהותית והגנרית של הסתבכות רב-חלקית, מה שהופך אותן למושכות ביותר ליישומים כמו חישה קוונטית ומטרולוגיה", הסביר יינג.
Key to the research is insight into delaying thermalization to maintain coherence, considered a critical research goal in quantum computing.

Quantum computing could positively impact all 17 UN Sustainable development goals
Advances in quantum computing technology have such broad applicability in the long term that they could positively impact all 17 United Nations Sustainable Development Goals. Quantum News Briefs summarizes הודעה אחרונה.
Standard Chartered and Universities Space Research Association are partnering on Quantum-Inspired Machine Learning for Environmental, Social and Governance applications to help meet these UN goals. The team aims to develop advanced machine learning approaches to forecasting natural disasters, such as floods and cyclones, and explore how current-generation quantum processors, future quantum computer designs and physics-based hardware solvers could be leveraged to improve beyond the state-of-art achievable by classical machine learning techniques.
The USRA quantum team in the Research Institute for Advanced Computer Science (RIACS), will test, evaluate and enhance aspects of highly performant classical models and also design hardware-software systems that use the most advanced quantum machines available on the cloud.
USRA’s Dr. דוד בל, Director of the Research Institute for Advanced Computer Science (RIACS) at USRA noted that “USRA is committed to advancing capabilities in environmental data sciences to help mitigate the impact of disasters such as wildfires and floods. This partnership brings together an interdisciplinary team of scientists in quantum computing, environmental data sciences and machine learning to examine how emerging technologies can be developed and applied to address computationally demanding problems in Enviromental, Social, and Governance (ESG) applications.”
At Standard Chartered, Elena Strbac, Global Head of Data Science and Innovation, said “We are excited to be renewing our partnership with our USRA colleagues in an area of such vital importance for the Bank, our clients, and our communities. We are keen to learn and to explore how quantum computing can help to accelerate the global goal to Net Zero, which is so critical for the future of our planet.”
