I remember reading a while ago about a group of quantum physicist that believe in a fundamental barrier to the construction of useful quantum computers. Is that still the case, or is it generally believed that a large-scale, useful quantum computer is simply a finite number of iterations away from reality?
- zardo 5y agoI think that view was based on the (probably correct) idea that sufficiently reliable physical qubits could not be built. The more qubits in the computer, the more reliable the qubits would need to be. Since the discovery of quantum ECC, that's no longer a reason to believe a quantum computer can't be built, a reliable logical qubit can be built out of a number of less reliable physical qubits.
