The breakthrough potential of quantum computers remains a ways off due to two crucial issues: error correction and computing power. In addition, the quality of qubits — aka quantum bits, the basic units of information for quantum computing — is not yet sufficient for longer calculations.
currently in existence would need ten quadrillion (10 to the power of 25) years to do the same — a number that far exceeds the age of the universe.
Better error correction
To calculate performance, Google used the with a qubit-virtualization system that it claimed broke a logical-qubit creation record. The company also aims to provide a commercial offering.
Recent breakthroughs, including Chinese researchers’ work to break RSA encryption with a quantum computer, have advisory bodies .
