Music as well as quantum this week since the Festival is on. The banners in the Cathedral depict bellringing changes. Artist Edward Bruce, architect Nick O’Neill. There’s a peal of 12 bells. The Cathedral has lunchtime recitals every day for the next two weeks, and other music.
IBM on quantum advantage .. quantum + classical advantage https://www.nextplatform.com/2025/08/05/ibm-outlines-steps-to-verify-claims-of-quantum-advantage/
IBM and Pasqual paper .. framework for measuring quantum advantage https://arxiv.org/pdf/2506.20658
IBM expects the first claims of quantum advantage will come from efforts in sampling problems, variational programs, and calculating the expectation values of observables. The challenge now will be to “rigorously confirm” when an advantage has occurred, the researchers wrote. Each part of the computation will have to be verified on their own merit through error detection and mitigation.
If this is the best that IBM can do to explain for what quantum computing should be used, compared to classical computing, there’s a lot of work to do yet.

quantum entanglement source chip comes in. Pandey called it, “the first building block of a quantum network.” And Nejabati outlined its power and unique attributes.
“Our chip can generate up to 200 million pairs of entangled photons per second,” Nejabati said. “That’s a very high rate. We do it by injecting laser light into our chip, which converts every single photon to two lower-energy entangled photons. And since they are entangled at telco frequency, they can be transported easily. You don’t need a special transport catalyst, just a normal fiber can transfer your entangled photons.” .. entangled particles can transfer or share information, across any distance, via a phenomenon known as teleportation.
“The beauty of it is that photons or other particles could be separated physically, even by a large distance,” “Entanglement actually allows us to transfer quantum information through the teleportation phenomenon.”

Trapped ion “Their solution starts with the iQPU, or integrated Quantum Processing Unit—a proprietary trapped-ion chip designed from the ground up for manufacturability and performance. Each chip is fabricated on a standard 200mm commercial foundry line, a decision that makes industrial scaling feasible. The iQPU itself hosts hundreds of ion qubits on a die larger than 400mm², making it the most spacious chip of its kind in development.
Critically, the chip uses global microwave control rather than relying on traditional laser-based systems. This removed much of the optical complexity found in competing designs and simplifies the overall architecture.
To stitch multiple iQPUs together, UQ developed UQConnect, a proprietary interconnect system that links chips at a rate of 2,424 connections per second, with an ultra-high fidelity of 99.999993%.
