The Helios platform is now available to customers through Quantinuum’s cloud service and on-premises offering. It has 98 Physical Qubits and 50 logical qubits with very low error rates. Launched Nov 2025, Quantinuum trapped-ion, Helios system is in a fully entangled GHZ state. They are fully error-corrected logical qubits at a ~2:1 physical-to-logical encoding rate …
Quera show 580 and 1156 logical qubits with neutral atom quantum computer simulations. April 2026 breakthrough (with Harvard/MIT) they shiow high-rate codes achieving over 50% encoding rate. They are using about ~2 physical qubits per logical qubit or better in simulations, with logical error rates in the teraquop regime. (1,152 physical → 580 logical; 2,304 …
QuEra will release a new roadmap to commercial quantum advantage in 2026. They presented progress to commercial quantum advantage over regular computers. They gave a talk at the Q2b 2025 conference (quantum to business). Brian WangBrian Wang is a Futurist Thought Leader and a popular Science blogger with 1 million readers per month. His blog …
Quantware has solved the fanout problem for superconducting quantum computers. They are making breakthroughs that can scale quantum computers to millons of qubits by 2029. They are at the Q2B silicon valley conference today at the Santa Clara convention center. QuantWare announces VIO-40K, a new scaling architecture for quantum chips which solves the bottlenecks of …
Publicly traded quantum companies, particularly the pure-play innovators, have delivered insane stock price runs over the past 1-2 years despite revenues that barely register. IonQ (IONQ), Quantum Computing (QUBT), Rigetti Computing (RGTI), and D-Wave Quantum (QBTS) dominate as publicly traded companies. The market caps collectively exceed $50 billion but with revenues totaling under $100 million. …
David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), the temperature at which – theoretically – matter ceases moving. Experts think that spin qubits (where information is encoded onto the magnetic direction of single electrons) …
Quantum computing breakthroughs from IonQ, D-Wave, QuEra, Alice & Bob, and others in the last six months, with dates, achievements, and their impact on error-corrected, scalable quantum systems. IonQ May 7, 2025, IonQ Demonstrated a 12% speed improvement over classical computing in a real-world simulation (heart pump modeling with Ansys). This shows practical quantum advantage …
Two weeks ago, D-Wave System announced a scientific breakthrough using their quantum annealing computers systems. They published in the esteemed journal @ScienceMagazine. Their newest annealing quantum computer outperformed one of the world’s most powerful classical supercomputers in solving a complex magnetic materials simulation problem with relevance to materials discovery. The new landmark peer-reviewed paper, Beyond-Classical …
Join Curt Jaimungal talks to Harvard physicist Jacob Barandes and Scott Aaronson. Jacob Barandes claims quantum mechanics can be reformulated without wave functions. Barandes has a new formulation of quantum mechanics which is considered a serious proposal by Scott Aaronson. Quantum computer theoretician Scott Aaronson gives his perspective. Barandes’ “indivisible” approach challenges the standard Schrödinger …
The Startup Alice and Bob have been working on the cat qubit. Alice & Bob is a Paris-based quantum computing startup founded in 2020 by Théau Peronnin and Raphaël Lescanne, with a mission to build the first universal, fault-tolerant quantum computer. Their main technological advantage is the proprietary “cat qubit” technology. With over 110 employees …
Microsoft team behind the recent breakthrough in physics and quantum computing demonstrated by the new Majorana 1 chip, engineered from an entirely new material that has the potential to scale to millions of qubits on a single chip. Microsoft today introduced Majorana 1, the world’s first quantum chip powered by a new Topological Core architecture …
