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.
Complex numbers model probability amplitudes, vectors model quantum states, and matrices model the operations that can be performed on these states. Programming a quantum computer is then a matter of composing operations in such a way that the resulting program computes a useful result in theory and is implementable in practice.
[5] [6] Hartmut Neven, founder and lead of Google Quantum AI, told the BBC that Willow would be used in practical applications, [4] and in the announcement blogpost expressed the belief that advanced AI will benefit from quantum computing. [1] Willow follows the release of Foxtail in 2017, Bristlecone in 2018, and Sycamore in 2019.
This article lists the companies worldwide engaged in the development of quantum computing, quantum communication and quantum sensing. Quantum computing and communication are two sub-fields of quantum information science , which describes and theorizes information science in terms of quantum physics .
A cylindrical protrusion from the center of the ceiling is a dilution refrigerator, containing a 20-qubit transmon quantum processor. [1] [5] It was tested for the first time in the summer of 2018, for two weeks, in Milan, Italy. IBM Quantum System One was developed by IBM Research, with assistance from the Map Project Office and Universal ...
[Editor’s note: “7 Quantum Computing Stocks to Buy for the Next 10 Years” was previously published in July 2022. It has since been updated to include the most relevant information available.]
IBM Heron is a 156-qubit tunable-coupler quantum processor created by IBM, originally unveiled during the IBM Quantum Summit 2023, which occurred on December 4, 2023, and is the highest performance quantum processor IBM has ever built. [1] [2] It is currently in use on the IBM Quantum System Two, unveiled during the same event. [1]
Possibly the greatest development in the broader digitalization sphere, quantum computers feature the potential to change everything we know about machine-driven calculations, thus auguring very ...
