"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 ...

Following up on Microsoft’s announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two ...

Universal gate set. A discrete set of gates is universal if the gates in the set can be arranged to make any unitary gate that is desired with arbitrary precision. An example of a two-qubit gate is a ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...

Many experts predict that practical fault tolerant quantum computing (FTQC) will require millions of physical quantum bits (qubits) but in August, 2023 IBM scientists ...
