Quantum computers that are actually useful 1 step closer thanks to new silicon processor that could pack millions of qubits

Scientists say they have reached “a critical inflection point” after developing a technology that makes silicon-based quantum processors more viable. Quantum computing company Equal1 has created a quantum processing unit (QPU) that can be built using conventional semiconductor manufacturing processes. This negates the complexity and expense typically involved with producing quantum processors using exotic materials […]

Monster 4,400-qubit quantum processor is ‘25,000 times faster’ than its predecessor

D-Wave has completed calibrating and benchmarking its latest processor — a 4,400-plus-qubit behemoth that it claims is 25,000 times faster than its predecessor. The Advantage2 quantum processing unit (QPU) is designed for complex applications including artificial intelligence (AI), materials science and optimization tasks. In a statement issued Nov. 6, D-Wave representatives said the new chip […]
