Rigetti Computing and IonQ use different approaches to quantum computing. Both companies have adequate cash levels to fund current operations. Of these two, is one a more attractive stock to buy? Although quantum computing is still a few years away from being widely used commercially,

IonQ is also heading toward profitability. IonQ narrowed its first-quarter non-GAAP loss to $0.14 a share from a loss of $0.19 a share a year ago. IonQ has made substantial progress as its unique linear ion chains in quantum computing help it to surpass 100 qubits and reduce errors compared to other quantum computers.

IonQ said Monday that it had agreed to acquire British quantum computing start-up Oxford Ionics in a deal valued at $1.075 billion. The transaction includes $1.065 billion in common stock and roughly $10 million in cash and is expected to close this year,
