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.
A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves , and quantum computing leverages this behavior using specialized hardware.
Artificial intelligence – computer mental abilities, especially those that previously belonged only to humans, such as speech recognition, natural language generation, etc. History of artificial intelligence (AI) Strong AI – hypothetical AI as smart as a human; Quantum computing. Timeline of quantum computing and communication
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 ...
For comparison, in 2014 it was estimated that a 1 exaFLOPS computer built in CMOS logic is estimated to consume some 500 megawatts of electrical power. [2] Superconducting logic can be an attractive option for ultrafast CPUs, where switching times are measured in picoseconds and operating frequencies approach 770 GHz.
IBM Quantum offers access to over 20 quantum computer systems. The IBM Quantum Experience offers free access to writing quantum algorithms and executing them on 5 qubit quantum computers. IBM's roadmap for quantum computing shows 65 qubit systems available in 2020 and 127 qubits to be available sometime in 2021.
Specifically, the company’s dilution systems, as explained by FormFactor, can create ultra-low temperatures below 10 mK that are essential for qubit and quantum processing unit development, and ...
As of December 2023, the concept has been used to demonstrate a 48 logical qubit processor. [6] [7] To perform computation, the atoms are first trapped in a magneto-optical trap. [6] Qubits are then encoded in the energy levels of the atoms. Initialization and operation of the computer is performed via the application of lasers on the qubits. [8]
