Quantum Device Challenges
India has edged past the United Kingdom by delivering more cutting-edge critical technology research during the period between 2019 and 2023, data published by the Australian Strategic Policy Institute on Wednesday (August 28) showed.
The institute updated its critical technology tracker this week by focusing on high-impact research or 10 per cent of the most highly cited papers, as a “leading indicator of a country’s research performance, strategic intent, and potential future science and technology capability”
The tracker covers 64 critical technologies and crucial fields spanning defence, space, energy, the environment, artificial intelligence (AI), biotechnology, robotics, cyber, computing, advanced materials, and key quantum technology areas.
The tin-vacancy center in diamond has properties that could be useful for quantum networks.
In a new study, researchers show how this defect’s electron spin can be controlled — and coherence prolonged — using a superconducting microwave waveguide.
Even the most pristine diamonds can host defects arising from missing atoms (vacancies) or naturally occurring impurities. These defects possess atomlike properties such as charge and spin, which can be accessed optically or magnetically. Over the past few decades, researchers have studied various defects to understand and harness these properties. One in particular—the tin-vacancy center, in which a tin atom resides on an interstitial site with two neighboring vacancies—exhibits exceptionally useful optical and spin properties, making it highly relevant in the field of quantum communication. Here, we explore how the spin properties behave under different magnetic field directions.
We demonstrate that manipulating electron spins is more straightforward in strained diamonds, as the electron spin is more responsive to an alternating magnetic field. We use superconductors known for generating no heat when a current flows through them, ensuring that we do not negatively affect the spin properties.
Through our simple fabrication steps, we illustrate how the properties of the tin-vacancy center can be fully utilized to advance the field of quantum computing and communication.

Researchers used D-Wave’s quantum computing technology to explore the relationship between prefrontal brain activity and academic achievement, particularly focusing on the College Scholastic Ability Test (CSAT) scores in South Korea.
The study, published by a multi-institutional team of researchers across Korea in Scientific Reports, relied on functional near-infrared spectroscopy (fNIRS) to measure brain signals during various cognitive tasks and then applied a quantum annealing algorithm to identify patterns correlating with higher academic performance.
The team identified several cognitive tasks that might boost CSAT score — and that could have significant implications for educational strategies and cognitive neuroscience. The use of a quantum computer as a partner in the research process could also be a step towards practical applications of quantum computing in neuroimaging and cognitive assessment.
Researchers have fabricated a quasi-one-dimensional van der Waals zirconium telluride thin film, which is a form of a substance that has long promised advances in quantum computing, nano-electronics and other advanced technologies. Until now, it has stumped scientists who have tried to manufacture it in large-scale quantities.
Summary: Researchers developed a brain-inspired AI technique using neural networks to model the challenging quantum states of molecules, crucial for technologies like solar panels and photocatalyst.
This new approach significantly improves accuracy, enabling better prediction of molecular behaviors during energy transitions. By enhancing our understanding of molecular excited states, this research could revolutionize material prototyping and chemical synthesis.
