- Six years ago today I started @rigetti. Best and most rewarding decision of my life (until I asked @susanthesquark to marry me :)
- I'm literally *shocked* at the insane shit coming out of some leading U.S. universities who are either explicitly victim-blaming and supporting violence and terrorism and Hamas, or strategically silent. WTF has happened to leadership at these places?
- Replying to @VivekGRamaswamyYou are just so off base, and losing all support from people you need for a viable campaign.
- Our Rigetti 80-qubit systems -- the world's first commercial multi-chip quantum computers -- now in private beta. Welcome to the world, Aspen-M! globenewswire.com/news-release/2…
- I'm excited to share what I've been working on with my incredible co-founder @IdaliaFriedson - we're building quantum-accelerated AI servers by combining multiple qubit modalities in one fault-tolerant architecture. Let's go! You can read more atSygaldry (@sygaldry_tech) is addressing the rising compute costs and energy requirements for AI by building quantum-accelerated AI servers to exponentially speed up training and inference. Congrats to @ChadRigetti and @IdaliaFriedson on the launch! ycombinator.com/launches/Nc7-s…
00:00sygaldry.comSygaldrySygaldry builds quantum-accelerated AI servers to exponentially speed up AI training and inference, cutting compute costs and improving energy efficiency - 1/ After spending the last decade building Rigetti Computing into a global quantum computing leader, I’m thrilled to kick off my next chapter as a venture investor. I’m thrilled to be joining Dutch quantum-focused fund QDNL Participations as a Venture Partner.
- Congrats to our extraordinary Rigetti team for launching our first quantum computer in the UK👏🏼! And thanks to our partners at Oxford Instruments, University of Edinburgh, Standard Chartered, and Phasecraft🙏🏼Today we are thrilled to announce the launch of our first UK-based quantum computer. Our 32-qubit Aspen-series system will be available to our UK partners over the cloud through Rigetti QCS™. globenewswire.com/news-release/2…
- My take on Google’s incredible scientific achievement and what it means for U.S. strategy and policy
- Yesterday we acquired QxBranch, a leading quantum applications company. It’s the first acquisition in the quantum industry. I wrote up a few thoughts here
- This is my favorite thing on the internet right now. It’s amazing when the success and momentum of a relatively tiny company triggers a behemoth to react. Go team @rigetti !
- Whether you are just getting started in your career, a second time founder, or something else altogether -- if you want to build an amazing company, you should apply to YC for Fall 2025 by August 4th. p.s. - YC is the YC for Deep Tech.Applications for the YC Fall 2025 batch are now open! Apply by August 4: ycombinator.com/apply
- Google’s supremacy demo and Amazon jumping into quantum computing are the biggest stories, but progress in variational (aka hybrid quantum/classical) algorithms is quietly one of the most important themes of the year in quantum.In 2019 I proved that the variational model of quantum computation is universal. 100% different than Lloyd's QAOA "reachability" result. New tricks awaiting applications and a general discussion RE practical limitations without error correction await. arxiv.org/abs/1903.04500
- Congratulations to John Martinis, Hartmut Neven, the incredible team at Google’s Quantum AI lab, and all their collaborators who helped make this happen. It’s a landmark scientific achievement and a very exciting day in quantum nature.com/articles/s4158…
