Thirteen-faced 'einstein' tile yields a nonrepeating crystal that steers light in new ways

Researchers at the University of Tokyo built a photonic crystal from a 13‑sided aperiodic tile nicknamed the 'einstein' (the Smith hat) by etching nanoscale holes in silicon nitride. The pattern never repeats, creating a nontraditional crystal that diffracts light into a swirling pinwheel pattern and, due to the tile’s lack of mirror symmetry, shows circular-polarization dependent scattering (chirality). This discovery could enable new ways to control light inside photonic chips for future optical communication and computing applications.

Lab chip promises 1,000x speed boost with no extra heat

A University of Tokyo team has demonstrated a non-volatile quantum switching chip element that stores bits via magnetism, potentially enabling 1,000 times faster processing with far less heat. In lab tests, it handled a single bit in 40 picoseconds (about 1/1,000th of current speeds) and remained stable through 100 billion cycles. If scalable, this could lower energy use in devices and data centers, but commercialization isn’t expected until around 2030 and is still at the prototype stage.

Mathematical Model Proposes Cell Revival After Death

Researchers at the University of Tokyo have developed a mathematical framework to redefine cellular death, focusing on whether cells can return to a 'living' state. This new model, based on enzymatic reactions and the second law of thermodynamics, aims to quantify the life-death boundary, potentially allowing scientists to better understand and control cellular death. The research could have significant implications for biological and medical studies, challenging the notion that death is irreversible.

"Advancements in Quantum Computing: From Error Correction to Fault-Tolerant Machines"

Researchers from the University of Tokyo, along with colleagues from Mainz University and Palacký University Olomouc, have demonstrated a new method for constructing a photonic quantum computer using a laser-generated light pulse that can consist of several photons. This approach provides an inherent capacity to correct errors, eliminating the need to generate individual photons as qubits via numerous light pulses and then have them interact as logical qubits. The research, published in the journal Science, shows the potential for transforming non-universally correctable qubits into correctable qubits using innovative quantum optical methods.

"Jack Ma becomes visiting professor at University of Tokyo amid tech empire retreat"

Alibaba founder Jack Ma gave his first lecture as a visiting professor at the University of Tokyo, teaching students about management philosophy and how to achieve success. Ma has largely retreated from his business empire following a crackdown by Beijing, which included the cancellation of Ant Group's IPO and a record fine for Alibaba. Ma's whereabouts have attracted continued interest as he was perceived to be representative of China's entrepreneurial confidence. Despite the crackdown, Beijing needs the private sector more than ever to shore up growth and create jobs.

Jack Ma Returns to Public Eye as Teacher and Mentor.

Jack Ma, the co-founder of Alibaba, made a public appearance at a math competition sponsored by the company in Hangzhou, China. Ma had withdrawn from public life in 2020 after criticizing Chinese regulators, which led to the scuppering of Alibaba's IPO. He has since taken up a teaching role at the University of Tokyo and was reported to have taught his first class on June 12. Alibaba's president, Michael Evans, recently confirmed that Ma is "alive," "well," and "happy."
