Researcher show that n-bit integers can be factorized by independently running a quantum circuit with orders of magnitude fewer qubits many times. It then use polynomial-time classical post-processing. The correctness of the algorithm relies on a number-theoretic heuristic assumption reminiscent of those used in subexponential classical factorization algorithms. It is currently not clear if the …
Without full fault tolerance in quantum computers we will never practically get past 100 qubits but full fault tolerance will eventually open up the possibility of billions of qubits and beyond. In a Wright Brothers Kittyhawk moment for Quantum Computing, a fully fault-tolerant algorithm was executed on real qubits. They were only three qubits but …
Many experts predict that practical fault tolerant quantum computing (FTQC) will require millions of physical quantum bits (qubits) but in August, 2023 IBM scientists published the discovery of new error correction codes that work with ten times fewer qubits. Practical error correction is far from a solved problem. However, these new codes and other advances …
Scientists are accelerating quantum simulations for the first time at supercomputing scale, thanks to NVIDIA cuQuantum with Xanadu’s PennyLane. Shinjae Yoo is leading the computational scientist and machine learning group lead at the U.S. Department of Energy’s Brookhaven National Laboratory where many researchers are running quantum computing simulations on a supercomputer for the first time, …
D-Wave Quantum Annealing systems are providing real business value to Mastercard and other companies. Steve Flinter of Mastercard presented a live demos of quantum-hybrid applications. The live demo showcased the technology’s applicability and potential impact in the financial services industry, with an application for customer loyalty and rewards programs. Mastercard is able to use D-Wave …
Superconducting fluxonium qubits provide a promising alternative to transmons on the path toward large-scale superconductor-based quantum computing due to their better coherence and larger anharmonicity. A major challenge for multi-qubit fluxonium devices is the experimental demonstration of a scalable crosstalk-free multi-qubit architecture with high-fidelity single-qubit and two-qubit gates, single-shot readout, and state initialization. Researchers present …
IBM Research has a goal of scaling quantum systems to a size where they’ll be capable of solving the world’s most challenging problems. IBM wants to deploy a quantum-centric supercomputer powered by 100,000 qubits by 2033. IBM has laid out a roadmap to reach 1000 qubit processors this year and 4000 qubits within two years. …
Nextbigfuture interviewed the President and COO of Quantinuum, Tony Uttley, and the scientific lead, Dr Henrik Dreyer. They have used the new H2 32 Qubit quantum computer chip to engineer the waveform of a new state of matter. They have engineered something called the Non-Abelian Topological Quantum state. Topological quantum computing has been one of …
Gavin Jones is a leading quantum chemist and manager in the IBM Quantum Computational Science group, as well as an IBM Quantum Technical Ambassador. In his research, Jones explores chemistry with quantum computers, such as the formation of functional advanced materials, catalysis, molecular properties, and polymer degradation. Gavin led a recent case study with JSR, …
A University of Bristol physicist provides the first-ever practical blueprint for creating in the lab a wormhole that verifiably bridges space, as a probe into the inner workings of the universe. It involves creating a new kind of quantum computer, investigation of quantuum physics in a new way and a possible path to some kind …
Google has a quantum computing goal of encoding a logical qubit on 1000 physical ones with an error rate of 0.0001% and they have achieved a 3% error rate using 17 qubits. The scaling or error reduction must be 20 times better. Using a 72-qubit chip, the Google team encoded a single logical qubit in …
