One downside with quantum computer systems is that they’ve a excessive error charge

IBM has managed to dramatically scale back the variety of quantum bits, or qubits, required to stop errors in a quantum pc. Its newest strategy to quantum error correction ought to deliver down the variety of qubits wanted to construct a helpful quantum machine.
The largest downside with right this moment’s quantum computer systems is that they’re noisy, which means they’ve error charges round 1 in 1000, whereas classical error charges are usually round 1 in 1 billion billion. …
