Quantum Zeitgeist

RIKEN protein model reaches 12,635 atoms using quantum-classical computing A research collaboration between Cleveland Clinic, RIKEN, and IBM has reached a new benchmark in molecular modeling, simulating a protein containing 12,635 atoms, the largest ever achieved using quantum computers, the company says.

Researchers have achieved over three orders of magnitude enhancement in upconversion emission by integrating lanthanide nanoparticles with a metasurface, potentially reshaping infrared imaging sensitivity. The work demonstrates a new approach to infrared-to-visible light conversion, where infrared information is transformed into visible photons using upconverting nanoparticles. The metasurface design maintains uniform enhancement across all relevant viewing angles, preserving image clarity.

Quantinuum, a quantum computing company listed on Nasdaq as QNT, will engage with investors at the Piper Sandler conference in Nashville, Tennessee, September 14-16. The company describes its hardware as the most accurate commercial general-purpose quantum computer, with industry-leading gate fidelities, a key metric for evaluating quantum processor performance.

Key Takeaways The Z3 claim needs every one of its qualifiers. It was the first programmable, automatic, digital computer that worked. It was not electronic, it did not store its program in memory, and it had no way to branch. He raised the quantum objection against himself. Calculating Space says in its own pages that a model behaving according to quantum physics would be extremely difficult to build. Summaries that present him as having answered it are overstating his case.

Stevens team boosts control of quantum states with new laser method Image: Jeffrey Vock · stevens.edu Stevens researchers have devised a method to control quantum systems while avoiding disruptions caused by intense laser fields. The team reports a solution using a series of precisely timed, low-intensity laser pulses to mimic the effect of a single, powerful burst of light.

Cryogenic testing is expanding beyond research labs and moving closer to semiconductor fabrication facilities as developers seek data across entire wafers, not just individual devices. Traditionally focused on characterizing single devices at extremely low temperatures, the field now prioritizes understanding how devices behave at scale and identifying process variation.

Researchers are refining electron transport in silicon-based qubits by employing a method previously identified by Langrock et al. as superior to bucket-brigade shuttling. Current silicon qubit designs are largely limited to linear, bilinear, or trilinear configurations, creating challenges for scaling and connectivity.

NVIDIA has extended the reach of its CUDA Toolkit to Windows on Arm systems, bringing GPU-accelerated computing to a new environment previously limited to Linux. CUDA Toolkit 13.4 adds functional support for the NVIDIA Rubin architecture (compute capability 107) as a preview, enabling developers to begin porting applications before CUDA support for Rubin reaches general availability in a future release of the CUDA Toolkit, the company says.

Key Takeaways He did not coin “black hole”. Robert Dicke used the comparison first and the journalist Ann Ewing put it in print on 18 January 1964. Wheeler adopted it in December 1967 and his standing made it stick. The weapons work was real and he never disowned it. He and Bohr published the theory of fission on the day Germany invaded Poland, he diagnosed the xenon poisoning that stalled the Hanford reactor, and from 1951 he ran Princeton’s thermonuclear programme.

Kristian Gogoran will present at unitaryCON26, a workshop co-hosted by Xanadu offices and the University of Toronto, connecting a commercial entity with the quantum open-source community. Attendees at the Unitary Foundation’s annual event, designed to advance open-source quantum software and hardware, can also find OrangeQS at booth 306 during IEEE Quantum Week in Toronto between September 13 and 18, the company says.
