Google Willow is a quantum computing chip with 105 qubits, promising to reduce error rates as it scales up.Willow recently performed a benchmark computation in under five minutes, which would take classical supercomputers 10 septillion years.Some physicists speculate that quantum computations like Willow's might involve parallel universes, although it remains in the realm of speculation.Despite its achievements, Willow's capabilities still do not pose a threat to modern cryptographic systems.
