New Quantum Computer Plugs Into a Wall Outlet — No Freezer Required

Most quantum computers need to be cooled to temperatures colder than outer space just to work. A new company called SAXON Q says it has built ones that don't. Its machines run at normal room temperature and plug into a regular wall outlet. Quantum computers are a type of computer that can solve certain hard problems much faster than the computers we use every day. But they are usually delicate. Most need giant refrigerators and sealed vacuum chambers to work, which makes them expensive and hard to run outside a specialized lab. SAXON Q's computers work differently. Instead of the usual hardware, they use small diamonds with tiny defects built into them on purpose. These defects, called nitrogen-vacancy centers, can store and process quantum information without needing extreme cold. The company is now selling two models: one with 128 qubits and one with 512 qubits. A qubit is the basic unit of information a quantum computer uses, similar to how a "bit" works in a normal computer. Both new machines are built to slide into a standard server rack, the kind of equipment shelf already used in most data centers. They run on regular power, not the special cooling and shielding systems other quantum computers need. SAXON Q says its machines are also far more energy efficient than the powerful graphics chips many companies currently use for heavy computing tasks. The company is aiming its computers at specific jobs: simulating chemical reactions, researching new materials, and running certain types of artificial intelligence models. These are areas where businesses have wanted to try quantum computing but didn't want to build the costly infrastructure it normally requires. This launch follows an earlier demo in April, when SAXON Q showed off a smaller, portable version of the same technology at a trade show in Germany. Experts who study quantum computing say removing the need for deep cooling is a major step toward making the technology practical for regular businesses. They also caution that it's still unclear whether diamond-based computers can grow powerful enough to beat today's best computers at real-world tasks.
