Optical circuit switch
PsiQuantum is demonstrating an optical circuit switch to potential customers, with a focus on AI data centers even as it builds toward a commercially viable quantum computer. The device’s insertion loss, or how much signal strength is reduced in transmission, is better than that needed by most of today’s GPU-based AI systems.
“This opportunity exists because we chose to solve the hardest scaling problems at the beginning of our roadmap to utility-scale quantum computing,” said Victor Peng, PsiQuantum CEO. “As AI computing pushes infrastructure to its limits, we now have an opportunity to put our state-of-the-art technology to work today while continuing toward our ultimate goal: building and deploying the world's first useful, fault-tolerant quantum computers.”

Your AI prompts are leaving out 80% of what you're thinking.
When you type a prompt, you summarize. When you speak one, you explain. Wispr Flow captures your full reasoning (constraints, edge cases, examples, tone) and turns it into clean, structured text you paste into ChatGPT, Claude, or any AI tool. The difference shows up immediately. More context in, fewer follow-ups out.
Used by teams at Microsoft, Amazon, and Notion. Try Wispr Flow free on Mac, Windows, iPhone, and Android.
Classiq
Intel is set to acquire Classiq, the quantum software company. Bloomberg reports that Intel will pay about $2.3 billion, and the deal is expected to close in the first half of 2027. Intel said Classiq’s software will continue to be available for integration with other companies’ platforms and a variety of quantum modalities.

Compute-per-watt
Matt Rijlaarsdam, CEO of the quantum processor company QuantWare, published an essay in EE Times arguing that “the industry needs a better yardstick [for measuring quantum computing’s performance].” Compute-per-watt should be the core metric: the amount of useful computation you get for each watt the system consumes. It pushes buyers and builders to weigh output against the energy that produced it, rather than counting the qubits and assuming the rest follows.”
