And in the news:

The Quantum winter is so bad consolidation has begun. I don’t know how I feel about this: Google Quantum AI has acquired Atlantic Quantum, an MIT-founded startup developing superconducting quantum hardware, to accelerate progress toward error-corrected quantum computers.

“We’re excited to announce Atlantic Quantum, an MIT-founded startup, is joining Google Quantum AI. Their work on integrated quantum hardware will accelerate our roadmap toward building a large scale error-corrected quantum computer” - Google Quantum aI

Honestly BigTech swallowing Quantum startup is bad news for the sector. At a time when IONQ 0.00%↑ IonQ is trading like a meme stock with barely any revenue what’s the incredible future we were talking about again?

BigTech to eat their lunch? This doesn’t make Google a leader in Quantum though, Google Quantum AI, which was founded in 2012, is on a mission to build quantum computers to solve otherwise unsolvable problems spun out Sandbox AQ, that has gotten so much funding. Google’s Willow chip PR was also underwhelming as compared to the reality.

Still I guess they want to grow: Atlantic Quantum’s modular chip stack combines qubits with superconducting control electronics in cold-stage systems. In theory, the acquisition aims to scale Google’s superconducting qubit hardware following recent Willow chip progress.

“Founded in 2012, Google Quantum AI has pursued a roadmap centered on superconducting qubits, with milestones including the 2019 “quantum supremacy” experiment and the recently introduced Willow chip.”
