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 ...

"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 ...

The Defiance Quantum ETF is rated Hold, reflecting stretched valuations and diluted quantum exposure despite a strong long-term theme. QTUM's equal-weight structure minimizes single-name risk but also ...
