Quantum computing isn't as far away as it seems. Every month, there seems to be a new breakthrough with the technology, and it makes the possibility of commercially viable quantum computing inch closer and closer. Most of the money in the quantum computing space will be made years before it becomes widely available, so it's imperative that investors devote a small amount of their portfolio to this rising industry. Three stocks I'm bullish on in the quantum sector are Alphabet (GOOG 1.14%) (GOOGL 1.26%), IonQ (IONQ +10.60%), and Nvidia (NVDA +1.70%). Each of them represents a unique way to invest in quantum computing, and all have major upside. 1. Alphabet Alphabet is one of the most potent competitors in the quantum computing space. It has some of the most resources of anyone competing, fueled by growing cash flows from its advertising, cloud computing, and artificial intelligence (AI) business segments. Furthermore, because it is self-funding, it doesn't need to advertise every breakthrough it achieves with its technology. This makes it a bit more secretive, but from what has been announced, it's clear that Alphabet is both a frontrunner in quantum technology and applications. Alphabet was one of the first to announce a quantum algorithm that actually provides a notable step forward toward real-world applications, like MRI scans. It has also developed the algorithm necessary to break cryptocurrency blockchain encryption with its quantum computing technology. All of this is made possible with its Willow quantum computing chip, which has 105 qubits, making it one of the more powerful quantum computing chips today. NASDAQ: GOOGL Key Data Points I think Alphabet is one of the biggest no-brainer investments in the quantum computing space, and will continue to impress investors with each announcement it makes. If quantum computing turns out to be a flop,
