Quantinuum-led Scientists’ Non-Abelian Topological Order Study Published in Nature

Posted by in categories: computing, quantum physics

Last year, a Quantinuum-led team of scientists announced that they were able to realize and control a state of matter known as non-Abelian topological order within a quantum processor. The team published their results in the pre-print server ArXiv, outlining how they accomplished what many experts considered a far-off advance — if possible at all – and what the scientists hoped could be an advance toward revolutionizing the way we approach quantum computing.

That advance has now been officially peer reviewed in Nature, marking another important step in the scientific process – and maybe even a significant step in the quest for fault-tolerant quantum computers, a quantum device that could handle operations with unprecedented accuracy and efficiency.

“Our key finding is that non-Abelian topological orders can experimentally be prepared with high fidelities on par with Abelian states like the surface code,” the team writes. “Non-Abelian states are among the most intricately entangled quantum states theoretically known to exist, and carry promise for new types of quantum information processing. Their realization evidences the rapid development of quantum devices and opens several new questions.”

Endovascular thrombectomy found to be beneficial for large ischemic stroke

Posted by in categories: biotech/medical, neuroscience

For patients with acute ischemic stroke and large cores, endovascular thrombectomy (EVT) improves clinical outcomes compared with medical management (MM), according to a study published online Feb. 7 in the Journal of the American Medical Association to coincide with the annual American Stroke Association International Stroke Conference, which was held from Feb. 7 to 9 in Phoenix.

Amrou Sarraj, M.D., from Case Western Reserve University in Cleveland, and colleagues describe the relationship between imaging estimates of irreversibly injured brain and at-risk regions and and EVT treatment effect in an exploratory analysis of the SELECT2 trial.

Adults with due to occlusion of the internal carotid or (M1 segment) and large ischemic core were randomly allocated to EVT versus MM across 31 global centers; the analysis included 336 patients.

The Limits of Immortality & Digital Death

Posted by in categories: biotech/medical, life extension

It is often thought that if we cure aging or find out how to upload a human mind that humans will be immortal. Today we will examine that notion and see how well it holds up against astronomical time lines.

Efficient and Sustainable Transplutonium Isotope Production: A New Diagnostic Approach

Posted by in categories: computing, military, nuclear energy, space, sustainability

In this study, a novel rapid diagnostic method was developed for optimizing the production of transplutonium isotope through high flux reactor irradiation. The proposed method was based on the concept of “Single Energy Interval Value (SEIV)” and “Energy Spectrum Total Value (ESTV)”, which significantly improved the production efficiency of isotopes such as 252Cf (by 15.08 times), 244Cm (by 65.20 times), 242Cm (by 11.98 times), and 238Pu (by 7.41 times). As a promising alternative to the traditional Monte Carlo burnup calculation method, this method offers a more efficient approach to evaluate radiation schemes and optimize the design parameters. The research discovery provides a theoretical basis for further refining the analysis of transplutonium isotope production, leading to more efficient and sustainable production methods. Future studies could focus on the implementation of energy spectrum conversion technology to further improve the optimal energy spectrum.

The production of transplutonium isotope, which are essential in numerous fields such as military and space technology, remains inefficient despite being produced through irradiation in a high flux reactor. Past studies on the optimization of transplutonium isotope production through irradiation in a high flux reactor have been limited by the computational complexity of traditional methods such as Monte Carlo burnup calculation. These limitations have hindered the refinement of the evaluation, screening, and optimization of the irradiation schemes. Hence, this research aimed to develop a rapid diagnostic method for evaluating radiation schemes that can improve the production efficiency of isotopes such as 252Cf, 244Cm, 242Cm, and 238Pu. The outcome of the study showed great potential in advancing the production of transplutonium isotope, which have numerous applications in fields such as military, energy, and space technology.
