IBM has unveiled a new quantum computing architecture it says will slash the number of qubits required for error correction. The advance will underpin its goal of ...

Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum states, leading to inaccurate computations. To address this problem, quantum ...

"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 ...

To overcome this problem, high-rate quantum codes, such as quantum low-density parity-check codes, have been considered. With this approach, the logical gates, which make calculations possible, have ...

Nov. 10, 2024 — The University of Sydney has announced that quantum researchers Dominic Williamson and Nouédyn Baspin have developed what the university called “a transformative new architecture for ...

The company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes. Quantum Computing ...

New QLDPC code family unlocks highly efficient quantum operations with lower physical qubit requirements VANCOUVER, British Columbia--(BUSINESS WIRE)--In an industry first, Photonic Inc. has ...

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 ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...
