IBM Research announced a 50 qubit quantum computer system in November, 2017. In a presentation in Sept, 2017, IBM indicated that they are doubling qubits every 8 months. If IBM maintains an 8 month qubit doubling rate then they will announce a 100 qubit quantum computer in June, 2018 a 200 qubit system in Feb, …
Modifying surface codes can improve quantum error correction 400 percent. The instability of qubits – the building blocks of quantum computers – means they are susceptible to error. Physicists have found that tweaking error coding can open the door to huge efficiency gains. The hack increases the error correction threshold of up to 43.7% – …
Quantum computer researcher Michelle Simmons was named 2018 Australian of the Year. A quantum computer is predicted to bring with it an exponential speed up in computational power. This is because instead of performing calculations one after the other like a conventional computer, a quantum computer works in parallel, looking at all the possible outcomes …
D-Wave Systems has commercially sold 2000 qubit quantum annealing systems. D-Wave System announced reverse annealing. Reverse annealing lets programmers start the search for the best solution at a localized spot in solution space. The system will then focus on the area which may be more promising for the best answer.D-Wave enables users to have more …
Japanese RIKEN researchers are trying to adapt existing the silicon metal–oxide–semiconductor field-effect transistors (MOSFETs) to integrate qubits with current electronics, offering the potential for scaling up quantum devices and bringing quantum computing closer to becoming a reality. Keiji Ono and colleagues from the RIKEN Center for Emergent Matter Science and the Toshiba Corporation in Japan, …
The (noisy) 50-100 qubit quantum computer is coming soon. (NISQ = noisy intermediate-scale quantum computer). NISQ devices cannot be simulated by brute force using the most powerful currently existing supercomputers. NISQ will be an interesting tool for exploring physics. It might also have useful applications. But we’re not sure about that. NISQ will not change …
In September, the Department of Energy awarded Lawrence Berkeley Labs of $3 million per year to construct a quantum computer and the software needed to operate it. Siddiqi’s team have already produced an 8 qubit superconducting system, with the ultimate goal of reaching 64 qubits. This would be the first time anyone in the U.S. …
IBM, Dwave Systems, Google, Rigetti, Intel and others are computing to develop faster quantum computing systems. In November, 2017, IBM announced a 50 qubit prototype quantum computer chip. IBM, Google and Rigetti are working on approximate gate model systems. Rigetti has a 19 qubit chip. The time to scale up and develop new chips with …
Rigetti has demonstrated unsupervised machine learning using 19Q, their new 19-qubit general purpose superconducting quantum processor. We did this with a quantum/classical hybrid algorithm for clustering developed at Rigetti. Arxiv – Unsupervised Machine Learning on a Hybrid Quantum Computer Machine learning techniques have led to broad adoption of a statistical model of computing. The statistical …
There five leading quantum computing approaches being explored worldwide: silicon spin qubits, ion traps, superconducting loops, diamond vacancies and topological qubits. University of New South Wales has new scalable CMOS chip design based on silicon spin qubits. They believe the design will scale to millions of qubits for universal computation and with error correction. The …
Researchers from Google and the University of California Santa Barbara have taken an important step towards the goal of building a large-scale quantum computer. Writing in the journal Quantum Science and Technology, they present a new process for creating superconducting interconnects, which are compatible with existing superconducting qubit technology. The race to develop the first …
