Actually if you want to know what the real ‘secret’ is 😀 it’s world-class research AND world-class engineering AND world-class infra all working closely together with relentless focus and intensity…
The secret behind Gemini 3? Simple: Improving pre-training & post-training 🤯 Pre-training: Contra the popular belief that scaling is over—which we discussed in our NeurIPS '25 talk with @ilyasut and @quocleix—the team delivered a drastic jump. The delta between 2.5 and 3.0 is

Our team, together with Oak Ridge National Laboratory, has performed the largest quantum ground state simulation of the Anderson model to date. This is the first simulation beyond the reach of exact diagonalization. The study used 70 qubits, four impurities, seven bath sites per

Weak nonunital noise allows local quantum circuits to perform computations of exponential depth without midcircuit measurements for error correction, thereby achieving computational complexity on par with noiseless quantum computers. @kunalsharmaq

RQS Summer School is underway at @IBM's NYC HQ! Nathalie De Leon of @Princeton helped kicked things off with a deep dive into #quantum sensing. This event brings together grad students & postdocs to explore challenges in quantum simulation and spark new collaborations.

We’re excited to share our plans for IBM Quantum Starling, expected to be the world’s first large-scale, fault-tolerant quantum computer. This new system, to be delivered to clients by 2029, is expected to perform 20,000x more operations than today’s quantum computers. Read more

In our preprint https://t.co/qHd4vSGI1D on the arxiv today, @Quantum_GiaGuar @A_Mezzacapo and I present a sample-based method to simulate thermodynamic uncertainty relations (TURs) with classical and quantum computers (up to 130 qubits).

It was a great experience to present a poster in 47th AICBC @niserbbs. Didn't expect to get the best poster award in my very first poster presentation. Felt so good and motivated after receiving the award 😊
Huge congratulations to @Kanika2895 for winning the best poster award!@DBS_IISERM @IiserMohali @pdfiisermohali

Happy to post a new paper, on graph states and IQP circuits, with collaborators from @UCBerkeley and @CWInl! 😀 How powerful are highly unstructured but easy-to-prepare quantum circuits? Let's try to answer in three parts. https://t.co/DJI8uoKVEg

Can we get practical quantum advantage from random circuit sampling at extremely shallow (even constant!) depth? 🔬 My new paper with friends from @williamandmary @UofMaryland @UWaterloo @QuantumIQC and @UChicago is a step towards the answer! 😃 https://t.co/fAOgTqN0te 1/9 📜
