Pure-play quantum stock
IonQ builds trapped-ion quantum computers and is aiming for 2 million qubits by 2030. That target is why it matters for Q-Day.

IonQ builds quantum computers that use trapped ions as qubits: individual charged atoms held in place by electromagnetic fields. Its current systems, IonQ Forte and Forte Enterprise, are available through the major cloud providers (IonQ).
In 2025 IonQ bought Oxford Ionics, whose ion traps are made on standard semiconductor chips, and moved into quantum networking with a majority stake in ID Quantique and the purchase of Qubitekk and Lightsynq (IonQ).
IonQ says it intends to deliver quantum computers with 2 million qubits by 2030 (IonQ). That is the number to watch. In May 2025, Craig Gidney of Google Quantum AI estimated that a 2048-bit RSA key could be broken in under a week by a quantum computer with fewer than one million noisy qubits (Gidney).
Two caveats. A company target is not a delivered machine. And Gidney's estimate assumes a specific design: a grid of qubits that runs error correction every microsecond. Qubit counts on different kinds of hardware do not compare one to one.
