One of my favorite investments in the quantum computing space is IonQ (IONQ 9.61%), and in its first-quarter report, it just revealed incredible top-line growth. Quantum computing is closer to reality than you may think Quantum computing is still a fledgling technology, but as companies like IonQ work toward producing commercially viable systems, they are securing partnerships with potential future customers in advance. Cutting-edge companies want to be ready so that when genuinely useful quantum computers become available, they are ready to hit the ground running. IonQ already boasts partnerships with several major companies, and it has become a top choice due to its technological edge. Quantum computers are all built around "qubits" -- quantum bits, their fundamental unit of information. But qubits can be created in several different ways, and all the players are using their own unique variations. So far, IonQ's technology holds the record for quantum computing accuracy. This is a big deal. Even the best current systems generate high levels of errors in their results, which is the primary reason that quantum computing isn't a commercially useful technology yet. NYSE: IONQ Key Data Points Another issue is the amount of computing power available. Just as traditional computers process information in bits, quantum computers use qubits. The more qubits in a system, the more powerful it is. IonQ is working toward its groundbreaking 256-qubit computer, which will be able to provide impressive results for those who deploy it, although even that will still be a bit too small for widespread commercial relevance. Still, the company announced its first system sale in the first quarter of this year. In Q1, IonQ's combined revenue from system sales and research contracts topped $64.7 million -- up 755% year over year. That's major growth for any company, and if IonQ can
