D-Wave is running a beta of a 21-qubit gate-model quantum simulator — the digital-circuit style of quantum computer, distinct from D-Wave's annealing systems — that models an error-locating qubit design in which losing one of two signal paths is
Classiq, a quantum software vendor, released a Fault Tolerance Engine that compiles high-level programs into plans for error-corrected chips, with the demonstration numbers modeled, not run on hardware.
Alice & Bob and ENS Lyon (École Normale Supérieure de Lyon) show a small superconducting circuit that bleeds off the photons that break multi-photon cat qubits, an oscillator-based error-correction design named for Schrödinger's cat, a step in the
A preprint finds that three diagnostic signals — operator entanglement (how a quantum state's information spreads across the circuit), stabiliser entropy (a structural measure of the quantum state), and out-of-time-order correlators, or OTOCs (a
An arXiv impossibility theorem shows bounded-degree quantum annealing solvers (a class of quantum optimization techniques restricted to low-order penalty interactions) can tie their math to thirteen decimal places and still overflow the plate (the
Anderon, IBM's quantum subsidiary at Albany NanoTech, is getting $1B from the federal CHIPS program to stand up a 300mm (the industry-standard wafer size) wafer line designed for quantum chips. IBM is matching the federal money dollar for dollar.
European IQM will deliver a 5-qubit Spark training system to Brazil's Eldorado; heavier work will run on a 54-qubit IQM system in Europe, leaving Brazilian research dependent on remote access.
European Patent EP 4462727 covers Quantum B's Quantum Conference Key Agreement (QCKA): shared quantum states let independent nodes agree without a classical majority. The company's quantum key distribution (QKD) is emulated, not physical.
NLM, LIGENTEC, and Spark Photonics combined an organic material with a glass-like chip base, opening a foundry path for quantum networks and trapped-atom systems (atomic clocks, quantum sensors).
A five-year, $375M federal R&D deal puts GlobalFoundries' Malta, NY fab on contract as a domestic source of the cryogenic control silicon that runs every major quantum hardware platform.
The company, formerly Viewbix, still runs the legacy ad-tech subsidiaries, and says the 'quantum-native' stack is in research and IP-filing stages.
