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 …
XAI has created Grokipedia and Grokipedia has a Nextbigfuture article. Nextbigfuture provided early coverage of Companies that Become deep tech Unicorns. Dozens of top Nucleqr fission and Fusion, quantum computer and Space Companies before They Became Billion $ Unicorns. There has been a surge in Grokipedia traffic to approximately 3.5 million daily visits, representing a …
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 …
Diamond color centers are a well researched field, but using them at scale as qubits was out of reach until recently. Their Quantum Transistor device (patent pending) resolves the charge stability issue and few more hurdles to enable using color centers as qubits. They presented at the Q2B 2025 conference. They could scale to 250,000 …
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. …
Quantum Brilliance’s is developing diamond quantum accelerators that will have over 50 qubits and outperform CPUs/GPUs of comparable size, weight and power in important applications. Quantum Brilliance believe their diamond integrated chips can be mass produced in the millions and can work along side regular chips as useful accelerators and sensors. They could also have …
Finnish company Semiqon has developed a transistor that operates with virtually zero heat dissipation. They have made silicon-based quantum processors to make future quantum computers more affordable, scalable, and sustainable. SemiQon has achieved new milestones in addressing the core challenges with scalability of quantum computers. Using its ultra-low-power cryogenic CMOS, SemiQon has now been able …
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) …
Alice & Bob, a global leader in the race for fault-tolerant quantum computing, announced today at GTC Paris the ongoing integration of the NVIDIA CUDA-Q platform with Dynamiqs. This combination outperforms the most widely used libraries today, accelerating the simulation of complex quantum dynamics by up to 75x, on early benchmarks. Alice & Bob has …
IONQ plans to have a fault-tolerant quantum computer by 2029 and they are acquiring Oxford Ionic for a about $1 billion. Some other important points: – Achieved 99.99% physical fidelity TODAY – Still on track for machine benchmarked at AQ64 this year – 50x density on single chip by going from 1D to 2D ion …
