Quantum processors are difficult to compare due to the different architectures and approaches. Due to this, published physical qubit numbers do not reflect the performance levels of the processor. This is instead achieved through the number of logical qubits or benchmarking metrics such as quantum volume , randomized benchmarking or circuit ...
For example, Microsoft is working on a computer based on the quantum properties of two-dimensional quasiparticles called anyons. [142] [143] [144] As part of this research, Microsoft unveiled Majorana 1 in February 2025, a quantum processor which leverages topological superconductors with potential Majorana zero modes.
IBM Osprey is a 433-qubit quantum processor created by IBM, revealed during the IBM Quantum Summit 2022, which occurred on November 9, 2022, in New York, United States. [1] It is 3 times larger than its predecessor, the IBM Eagle. [2] [better source needed] It needs to be cooled down to a temperature of ~0.02 K (-273.13 °C).
Quantum computing. Timeline of quantum computing and communication; Moore's law – observation (not actually a law) that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every two years. The law is named after Intel co-founder Gordon Moore, who described the trend in his 1965 paper ...
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 ...
As of 2023, superconducting computing is a form of cryogenic computing, as superconductive electronic circuits require cooling to cryogenic temperatures for operation, typically below 10 kelvin. Often superconducting computing is applied to quantum computing, with an important application known as superconducting quantum computing.
Therefore, the first five criteria ensure successful quantum computing, while the final two criteria allow for quantum communication. A scalable physical system with well characterized qubits. "Well characterized implies that that Hamiltonian function must be well-defined i.e. the energy eigenstates of the qubit should be able to be quantified..
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 ...
