PsiQuantum plans to build a large-scale quantum computer using photons, leveraging existing chip manufacturing infrastructure, with a $1B investment and a target operational timeline in 2027.
The article discusses the 'AI power wall' where compute growth outpaces efficiency gains, proposing four paradigm shifts—neuromorphic, photonic, memory-centric, and approximate computing—to make AI sustainable, and promotes the upcoming 'Watt Matters in AI' conference addressing full-stack energy reduction.
Q.ANT has opened a US facility in Austin and appointed Bruno Spruth as CTO, highlighting production of photonic GPUs at the Leibniz Supercomputing Centre that claim significant performance and energy efficiency gains over traditional transistor-based chips.
