Qubits or quantum bits are the fundamental building block for quantum information processes. Whereas conventional computers store and process data as a series of ‘1’s and ‘0’s, quantum computers use the properties of a quantum system, such as the polarization of a photon or the spin of an electron.

    The physics of large systems is often understood as the outcome of the local operations among its components. Now, it is shown that this picture may be incomplete in quantum systems whose interactions are constrained by symmetries.

    The dynamics of quantum information and entanglement is closely linked to the physics of thermalization. A quantum simulator comprised of superconducting qubits has measured the spread of quantum information in a many-body system.

    The reliability of quantum computers depends on the correction of noise-induced errors, which requires additional resources. Experiments on superconducting qubits have now demonstrated the capabilities of a less-demanding scheme for error detection.

    Qubits come in many shapes and forms. Some are better developed, some will make it easier to scale up to big quantum processors and some will require less effort to correct errors. One thing they have in common: they will all benefit from materials optimization.
