McKinsey estimates the quantum computing industry could reach $72 billion in revenue by 2035. Three stocks positioned for this are Alphabet, IonQ, and Nvidia. Alphabet is using its resources to develop its Willow quantum chip, which just showed positive results with their Quantum Echoes algorithm. IonQ is a smaller upstart using an ion trap approach instead of the usual superconducting method. This gives them an edge in accuracy, which is a major hurdle right now. Nvidia isn't actually building a quantum computer. Instead, they are making interface tools so these machines can plug into existing traditional networks for a hybrid approach.
