pls note a difference between a 'logical qubit' and a 'physical qubit'.. currently they don't have even 1 logical qubit, and for quantum computer to be of any u

  >currently they don't have even 1 logical qubit wut? different QEC produce differently sized logical qubits and there are absolutely machines with enough physical qubits to amount to a logical qubit: https://www.ncbi.nlm.nih.gov/books/NBK538709/#:~:text=In%20Shor's%20QEC%20code%2C%20the,errors%20on%20the%20data%20qubit https://www.ncbi.nlm.nih.gov/books/NBK538709/#:~:text=In%20S.... and realized QEC is definitely not far off https://www.nature.com/articles/ncomms7979 https://www.nature.com/articles/ncomms7979 >for quantum computer to be of any use it should have >10k logical qubits i'm aware and yet it's false to claim that these things don't compute. for the time being they're noisy computers but they're still computers.
