Fujitsu has a Digital Annealer with 8192 Qubits and a 1 million qubit system in the lab. This is a classical hardware emulation of quantum annealing (analog) system. This is not a quantum computer but hardware emulation. David Worral, Head of Quantum Technologies at Cambridge Quantum Computing, indicated that Fujitsu has a 1 million qubit …
D-Wave Systems has shown its new 5000 qubit quantum annealing system that uses a vastly improved Pegasus architecture. Nextbigfuture wrote about the Pegasus architecture and the 5,640 qubit D-Wave prototype back in mid-January. D-Wave has now officially announced the 5000+ qubit system and the new architecture. The next-generation D-Wave quantum platform will include ongoing updates …
D-Wave Systems announced a developer preview of D-Wave Hybrid™, a simple, open-source hybrid workflow platform for building and running quantum-classical hybrid applications. D-Wave Hybrid will become part of the Ocean software development kit within D-Wave’s Leap™ Quantum Application Environment (QAE) and is available at https://github.com/dwavesystems/dwave-hybrid for trial and developer input. The D-Wave Hybrid framework provides …
D-Wave Systems published a milestone study demonstrating a topological phase transition using its 2048-qubit annealing quantum computer. This complex quantum simulation of materials is a major step toward reducing the need for time-consuming and expensive physical research and development. “Observation of topological phenomena in a programmable lattice of 1,800 qubits,” was published in the peer-reviewed …
Rigetti Computing has designed a microchip for quantum computers that would have more than six times as many qubits as Rigetti’s current 20 qubit machines. That would be more powerful than IBM’s 50-qubit computer and more powerful than Google’s 72-qubit machine. Rigetti is hoping to build a functioning computer with 128 qubits in the next …
D-Wave Systems is involved in a grant-funded UK project to improve logistics and planning operations using quantum computing algorithms. The work will focus on an area known as AI/Hierarchical Task Network planning techniques, used to optimize resource management and operations for a wide range of industries including law enforcement, telecommunications, and transportation. In 2018, the …
D-Wave Systems, the leader in quantum computing systems and software, announced that it has met the key conditions to lock in new funding of $20 million. In April 2017, D-Wave closed on the first $30 million tranche of convertible notes and received a conditional commitment from Public Sector Pension Investment Board (PSP Investments) for an …
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% – …
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 …
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 …
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 …
