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
Computer engineers typically describe a modern computer's operation in terms of classical electrodynamics.Within these "classical" computers, some components (such as semiconductors and random number generators) may rely on quantum behavior, but these components are not isolated from their environment, so any quantum information quickly decoheres.
The spin qubit quantum computer is a quantum computer based on controlling the spin of charge carriers (electrons and electron holes) in semiconductor devices. [1] The first spin qubit quantum computer was first proposed by Daniel Loss and David P. DiVincenzo in 1997,.
A working mechanism of a resonant tunnelling diode device, based on the phenomenon of quantum tunnelling through the potential barriers. Diodes are electrical semiconductor devices that allow electric current flow in one direction more than the other. The device depends on a depletion layer between N-type and P-type semiconductors to serve its ...
Quantum simulators are types of quantum computers intended to simulate a real world system, such as a chemical compound. [ 29 ] [ 30 ] Quantum simulators are simpler to build as opposed to general purpose quantum computers because complete control over every component is not necessary. [ 29 ]
Quantum computing stocks rebounded Tuesday after a massive sell-off fueled by Big Tech CEOs expressing skepticism. The stocks recovered as D-Wave CEO Alan Barrett said quantum computing is "real."
The sector's leading industry giants, like Google, IBM and Baidu, are using superconducting quantum computing and transmon qubits to make leaps and bounds in the area of quantum computing. In August 2022, Baidu released its plans to build a fully integrated top to bottom quantum computer which incorporated superconducting qubits.
