QUANTUM COMPUTING

Designer pulses for better qubit gate operations

Nature Electronics volume 2, pages 140–141 (2019)Cite this article

Subjects

Error rates in silicon qubits can be improved by benchmarking and optimizing pulse engineering techniques.

Quantum computers have developed rapidly in the last decade, bringing their disruptive capabilities closer to market. By harnessing the unique features of the quantum world, such as quantum superposition, they could provide unprecedented computational power and help solve some of society’s greatest challenges. In particular, by directly encoding information into quantum many-body states, a small number of quantum bits — or qubits — can replace an exponential number of classical bits. This quantum-enhanced computational capability could then be used, for example, to reduce our impact on the climate through more energy-efficient materials and to design more effective drugs to cure diseases.
