AT&T Expands D-Wave Partnership to Optimize Telecom Network Operations and Agentic AI

Telecommunications leader AT&T (NYSE: T) has signed a commercial agreement with D-Wave Quantum Inc. (NASDAQ: QBTS) to expand its use of quantum annealing technology across its network infrastructure operations. Building on initial pilot benchmarks—where D-Wave's quantum annealing hardware reduced a network optimization processing workload from one hour down to under 15 seconds—AT&T plans to integrate [...] The post AT&T Expands D-Wave Partnership to Optimize Telecom Network Operations a...

Quantum neural networks get their first hardware test

Neural networks have transformed how machines find patterns in data, from recognizing faces in photos to predicting the shapes of proteins. So far, all of this progress has been made on ordinary classical computers, but with quantum computers now edging into practical use, there is a real possibility that neural networks could tap into distinctly quantum effects and operate in ways that classical machines never could. So far, however, neural networks have proven far more difficult to run on q...

New Metastable States in Ytterbium Ions Promise Breakthroughs for Quantum Computing and Atomic Clocks

Researchers have identified long-lived metastable states in ytterbium ions, with lifetimes reaching over 30 seconds. This discovery could significantly enhance the efficiency of qubit detection in quantum computers and improve the precision of atomic clocks.
