A double quantum dot. Each electron spin S L or S R define one quantum two-level system, or a spin qubit in the Loss-DiVincenzo proposal. A narrow gate between the two dots can modulate the coupling, allowing swap operations. The Loss–DiVicenzo quantum computer proposal tried to fulfill DiVincenzo's criteria for a scalable quantum computer ...
This list contains quantum processors, also known as quantum processing units (QPUs). Some devices listed below have only been announced at press conferences so far, with no actual demonstrations or scientific publications characterizing the performance. Quantum processors are difficult to compare due to the different architectures and approaches.
Xanadu was founded in 2016 by Christian Weedbrook and was a participant in the Creative Destruction Lab's accelerator program. Since then, Xanadu has raised a total of US$245M in funding with venture capital financing from Bessemer Venture Partners, Capricorn Investment Group, Tiger Global Management, In-Q-Tel, Business Development Bank of Canada, OMERS Ventures, Georgian, Real Ventures ...
Google has unveiled its new chip, Willow, which outperforms current computer benchmarks. Google says the chip solves a 30-year hurdle and advances quantum computing for commercial uses. Tech ...
The qubits in quantum computing are more prone to mistakes than a regular computer because they are highly sensitive to electromagnetic and other forms of interference and can only remain in a ...
Quantinuum is a quantum computing company formed by the merger of Cambridge Quantum and Honeywell Quantum Solutions. [1] The company's H-Series trapped-ion quantum computers set the highest quantum volume to date of 1,048,576 in April 2024. [ 2 ]
Quantum computers might soon actually be useful, researchers have said after a new breakthrough. A new study showed that a quantum computer could be used for calculations that are beyond the ...
Quantum dot computer, spatial-based (qubit given by electron position in double quantum dot) [9] Quantum computing using engineered quantum wells, which could in principle enable the construction of a quantum computer that operates at room temperature [10] [11] Coupled quantum wire (qubit implemented by a pair of quantum wires coupled by a ...
