Atom Computing Achieves Fault‑tolerant Quantum Breakthrough, Gets $100M Support
Massive step closer to fault tolerant #quantum computing by @DCVC-backed @Atom_Computing—a world first on a neutral atom system at this scale. This proof, on commercially viable Atom systems capable of over 1000 qubits (with a clear, near-term roadmap to orders of magnitude more), shipping and running today, was one of the many breakthroughs that compelled the Commerce Department to support Atom Computing with $100 million.

Microsoft's Majorana 2 Chip Accelerates Quantum Computing Timeline
Microsoft’s next-gen quantum chip cuts timeline to useful quantum computing. Microsoft’s Majorana 2 chip uses a new material stack that promises quantum computing much sooner. Details 👇https://t.co/dGw8Yj2Hcx
Same Chip, Different Bins: Temperature Dictates Design Limits
Industrial High-T chips exist for specific markets. From 0-105C to -40-150C. They get binned differently for reliability and to honour the warranty, but otherwise are the same chip as the consuner/enterprise grade. It's an electromigration test. Beyond that at extreme...
Register by May 31 for UCLA Quantum Workshop
Last chance to register for the 2026 Quantum Device Design Workshop at UCLA: https://t.co/cLUroSiRku The deadline to register is May 31.
Measurement-Based Fourier Sampling Solves Hidden Symmetry Problems
What role do measurements play in quantum algorithms? We systematically explore this question in the context of a greatly simplified quantum algorithm for the abelian hidden subgroup problem for states (StateHSP), featuring substantially reduced circuit complexity. In this work, we...
QUBT: Pure‑Play Quantum Firm Tied to Tech Giants
$QUBT Quantum Computing Inc. (QUBT) is one of the few pure-play public quantum companies focused on photonics, AI acceleration, and quantum infrastructure. Its ecosystem exposure includes: NVIDIA ($NVDA) AMD ($AMD) Intel ($INTC) IonQ ($IONQ) Rigetti ($RGTI) D-Wave ($QBTS) Alphabet ($GOOGL) Amazon ($AMZN) Microsoft ($MSFT) TSMC ($TSM)
Braiding Fibonacci Anyons Enables Universal Quantum Gates
How can we build universal quantum gates by braiding exotic particles that don't exist in free space? Fibonacci anyons are quasiparticle excitations of topologically ordered quantum states whose braiding statistics are rich enough to perform universal quantum computation.
Bridging Four Key Gaps Toward Quantum Advantage
Mind the gaps: The fraught road to quantum advantage Quantum computing is advancing rapidly, yet substantial gaps separate today's noisy intermediate-scale quantum (#NISQ) devices from tomorrow's fault-tolerant application-scale quantum (#FASQ) machines. https://t.co/aSWIa4Z6CA In this perspectives article, @preskill and I identify four related hurdles...
IBM Spins Out First U.S. Quantum Manufacturing Foundry
IBM wants to turn its captive quantum fab into an industry fab. A proposed $1B CHIPS award + $1B @IBM cash plus IP and workforce spins out "Anderon", what could be America's first foundry purpose-built solely for quantum manufacturing. Not greenfield....
Blind Quantum Computing Achieved on Modular Superconducting Processor
Do you wonder how you can execute a #quantum algorithm on a quantum server in a way that the operator of the server does know neither the task nor the result? Here we conceptually demonstrate blind quantum computing using ...
Modular Quantum Processor Simulated to Factor 2048‑bit RSA
A little behind on this, but an arxiv paper came out last week on factoring 2048-bit RSA integers with a modular atomic processor. It's an end-to-end analysis of distributing Shor's algorithm, which is needed for the modular roadmaps. Key point: •...
Santander Launches €120k Quantum‑AI Challenge with IBM
Santander is putting capital into quantum and AI. Their 'Quantum AI leap' global challenge, backed by IBM, offers €120k in prizes for startups and scaleups building solutions in quantum hardware, software, and PQC. Applications close June 30! (but quantum has...
Quantum Computing Leverages Interference, Not Parallel Evaluation
It's the line you'll see in nearly every popular explainer: "a quantum computer evaluates all possibilities in parallel." It's wrong. Qubits, superposition, measurement, entanglement. We have quantum systems, ok. They can hold many states at once and link those...
From LC Oscillator to Transmon: Building Superconducting Qubits
How do you actually make a qubit from a superconducting circuit? Superconducting qubits are one of the leading platforms for quantum computing, but the path from an LC oscillator to a functioning transmon qubit involves some complex (and fascinating) physics.
Scaling Quantum Computers Requires Modular Cryogenic Architecture
Really liking Matthias Troyer's (Microsoft) posts on new engineering challenges in quantum computing architectures. The qubit isn't the only problem (we all know that). Why are we going to modular systems? Lecture 5 walks through why utility-scale quantum hits a...
