OQC builds quantum chips by placing transmon qubits atop a thin layer of sapphire. According to the company, its engineers create the qubits using photolithography techniques and an electron beam. The other side of the sapphire substrate hosts devices called resonators that are responsible for extracting calculation results from qubits.

With the release of its new Majorana 2 chip, Microsoft claims agentic AI has dramatically accelerated its timeline to scale a commercial-grade quantum computer.

Researchers at Monash University have built a tiny on-chip circuit that can generate, direct, and read light-based information for both artificial intelligence inference and quantum computing operations.

Court filings have revealed IBM intends to make a massive five-year investment to be the first company to commercialize quantum computing.

For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors,

Quantum computing is still in its infancy and requires massive, long-term investments — which means investing in quantum is highly speculative, based on future potential.

The quantum computing trade has shifted from a speculative bet to an identifiable, investable theme, and the three exchange-traded funds that best capture it each take a different angle on the same transition.
