One of the deepest ambitions in modern physics is understanding how the fabric of space and time could emerge from ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

"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 ...

Their framework, outlined in a paper published in Nature Physics, specifically proposes the construction of quantum codes that are defined on spheres. "In graduate school, I was part of a team of ...

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 ...
