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 ...
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 .
Quantum computing stocks rose in premarket trading on Thursday after Microsoft launched a new chip that indicated the technology is not "decades away" as stated by the top boss of AI chip ...
The best-known quantum computing companies all use different methods for developing quantum computers and determining the position of qubits in their chips. Each company will argue in favor of its ...
Microsoft on Wednesday announced a new kind of quantum computer chip that it says will make quantum computers useful in years, rather than decades in the future.The chip, called Majorana 1, uses ...
Hartmut Neven, founder of Google Quantum AI, prompted controversy [7] [8] by claiming that the success of Willow "lends credence to the notion that quantum computation occurs in many parallel universes, in line with the idea that we live in a multiverse, a prediction first made by David Deutsch." [1]
Google says the chip solves a 30-year hurdle and advances quantum computing for commercial uses. Tech leaders, including Sam Altman and Elon Musk, have praised the development.
While there are now plenty of companies working on quantum computing, International Business Machines (NYSE: IBM) is a pioneer. The company's researchers built the first functioning computer using ...
