Amazon Web Services today announced Ocelot, its first-generation quantum computing chip. While the chip has only rudimentary computing capability, the company says it is a proof-of-principle demonstration—a step on the path to creating a larger machine that can deliver on the industry’s promised killer applications, such as fast and accurate simulations of new battery materials.

“This is a first prototype that demonstrates that this architecture is scalable and hardware-efficient,” says Oskar Painter, the head of quantum hardware at AWS, Amazon’s cloud computing unit. In particular, the company says its approach makes it simpler to perform error correction, a key technical challenge in the development of quantum computing.  

Ocelot consists of nine quantum bits, or qubits, on a chip about a centimeter square, which, like some forms of quantum hardware, must be cryogenically cooled to near absolute zero in order to operate. Five of the

In-brief analysis

February 26, 2025

According to our Natural Gas Annual Respondent Query System, 1,653 natural gas delivery companies delivered natural gas to end-use customers in 2023 in the United States. A delivery company is defined as any entity that delivers natural gas directly to end users. Natural gas deliveries by pipeline companies to the electric power sector made up the largest share of deliveries to end-use consumers, accounting for 33% of all natural gas delivered to end-use consumers in 2023.

Pipeline companies generally deliver large volumes of natural gas to high-volume end users, accounting for most of the deliveries to industrial facilities and electric power plants. The electric power sector and industrial sector are the largest and second-largest consuming sectors, respectively. Pipeline companies delivered 75%, or 27.1 billion cubic feet per day (Bcf/d), of the natural

Wherever humans go, we take some form of insulation with us to keep us at just the right temperature. But just because the idea is old doesn’t mean that there haven’t been innovations. One of those innovations could lower your energy costs.
