Improving the magnetic bottle that controls fusion power on Earth

Scientists who use magnetic fields to bottle up and control on Earth the fusion reactions that power the sun and stars must correct any errors in the shape of the fields that contain the reactions. Such errors produce deviations ...

Optical toric code platform sets new record

Anyons form the basis for topological quantum computation and error correction, where the topological aspect of anyonic braiding is one of the important features that gives rise to fault tolerance. More qubits to control ...

Immunizing quantum computers against errors

Building a quantum computer requires reckoning with errors—in more than one sense. Quantum bits, or "qubits," which can take on the logical values zero and one simultaneously, and thus carry out calculations faster, are ...

A faster method to read quantum memory

The potential computing revolution that quantum computers have long promised is based on their weird property called superposition. Namely, qubits can take both logical states 0 and 1 simultaneously, on top of any value in ...

Coping with errors in the quantum age

Quantum systems can be manipulated with extremely high precision, but not perfectly. Researchers in the Department of Physics at ETH Zurich have now demonstrated how to monitor and correct errors that occur during such operations.

Tests show integrated quantum chip operations possible

Quantum computers that are capable of solving complex problems, like drug design or machine learning, will require millions of quantum bits—or qubits—connected in an integrated way and designed to correct errors that ...
