Scientists at the Institute of Science Tokyo have announced a breakthrough in quantum error correction that could bring a large-scale quantum computer closer to ...
"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...
IBM's new chip design cuts the physical qubits needed per logical qubit from thousands to 144, slashing the hardware bill for fault tolerant quantum computing.
On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...
Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...
Error-correcting codes defined over finite fields form the cornerstone of reliable digital communication and data storage. Such codes exploit the algebraic structure of finite fields—denoted GF(q)—to ...
The real world can be complex and unpredictable, where the behaviors of even the most steady and proven mechanisms can be fraught with unanticipated outcomes. In technological fields, scientists and ...
Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...
For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...
