Error Correction

The researchers built a system (circuit diagram on the left) that can be controlled by microwave pulses (wiggly arrow) to turn on or off different operations. This system creates a special quantum state (cubic phase state) useful for fixing errors in quantum computers. The blue areas on the right show a unique property (Wigner negative regions) that proves this state is truly quantum.

Photon-Based Approach Promises Error-Resilient Logical Qubits

While errors are normally hard to spot in quantum devices, researchers have shown that, with careful control, some errors can cause atoms to glow. Researchers used this capability to execute a quantum simulation using an array of atoms and a laser beam, as shown in this artist's concept. The experiment showed that they could discard the glowing, erroneous atoms and make the quantum simulation run more efficiently.

A new way to erase quantum computer errors

MIT researchers have developed a technique that greatly reduces the error in an optical neural network, which uses light to process data instead of electrical signals. With their technique, the larger an optical neural network becomes, the lower the error in its computations. This could enable them to scale these devices up so they would be large enough for commercial uses.
