We may be on the cusp of quantum supremacy. But what does that actually mean?

Researchers have made significant progress in the quest for scalable and fault-tolerant quantum computers after entangling the most logical qubits on record.

Google's new 105-qubit 'Willow' quantum processor has surpassed a key error-correction threshold first proposed in 1995 — with errors now reducing exponentially as you scale up quantum machines.

Scientists have created a single unit of quantum information using a superconducting circuit and a vibrating sapphire crystal.

A chance discovery by researchers could drastically lower the energy needed for next-generation memory technologies.

The new type of transistor, known as the "cryo-CMOS transistor," is optimized to operate at temperatures under 1 K and emit near-zero heat.

Scientists in Australia say they've cracked a key hurdle facing the the development of scalable quantum computers and practical quantum data storage.

D-Wave says its new Advantage2 processor, which is designed for complex applications in AI, optimization and data science, is faster and more accurate than its existing 5,000-qubit system.

When combined with Qiskit software tools, the 156-qubit R2 Heron quantum processor can perform 5,000 two-qubit gate operations — double the previous best — meaning it's ready for complex quantum computations, IBM scientists say.
