qubit

A reconfigurable spin iceSpin ices, magnetic systems in which local spins respect the so-called ice rules, can occur in natural materials or be engineered in patterned arrays. King et al. used superconducting qubits to implement a…

SummaryQuantum computers (QCs) promise to exponentially speed up a number of problems in optimization, materials science, and chemistry. The caveat is that they may not even get the chance. One outstanding issue is the coherence time, which…

Superconducting spin qubitTo date, the most promising solid-state approaches for developing quantum information-processing systems have been based on the circulating supercurrents of superconducting circuits and manipulating the spin…
