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
Sycamore is a transmon superconducting quantum processor created by Google's Artificial Intelligence division. [1] It has 53 qubits. [2] In 2019, Sycamore completed a task in 200 seconds that Google claimed, in a Nature paper, would take a state-of-the-art supercomputer 10,000 years to finish. Thus, Google claimed to have achieved quantum ...
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 .
D-Wave Two (project code name Vesuvius) is the second commercially available quantum computer, and the successor to the first commercially available quantum computer, D-Wave One. Both computers were developed by Canadian company D-Wave Systems. [1] The computers are not general purpose, but rather are designed for quantum annealing.
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 ...
www.ibm.com /quantum /blog /quantum-roadmap-2033 IBM Condor is a 1,121- qubit quantum processor created by IBM , unveiled during the IBM Quantum Summit 2023, which occurred on December 4, 2023. It is the 2nd largest quantum processor (in terms of qubits), just shy of the 1,125-qubit quantum processor by the company Atom , created in October 2023.
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]
Bose–Einstein condensate-based quantum computer [27] [28] Transistor-based quantum computer (string quantum computers with entrainment of positive holes using an electrostatic trap) Rare-earth-metal-ion-doped inorganic crystal based quantum computer [29] [30] (qubit realized by the internal electronic state of dopants in optical fibers)
