Quantum technologies get ahead: one discovers material to store quantum information

Fazel Tafti, a researcher from Boston College, has made a breakthrough in the development of quantum technologies. He has discovered a new method of producing spin liquid, an innovative material required for a long-term storage of quantum information.

Spin liquid is one of the states of matter, which is extremely rare. Tafti has managed to obtain it out of copper iridate: a compound of copper, oxygen and iridium. According to the researcher, the atomic structure of this matter looks like the honeycomb. Such a structure leads to a phenomenon called magnetic frustration: the spins of electrons in this matter keep moving and never freeze unlike solid matter atoms even if the temperature of such liquid is reduced up to zero.

Besides other properties, spin liquid features long-range entanglement: in this environment, one particle’s quantum state is twinned with that of another particle some distance away. It is this very property that quantum computer founders are interested in, as it allows to maintain the integrity of the qubits.

A paramount importance of the study is that one has discovered the method, which is also the way to discovering other matters. Moreover, one of such matters will eventually result in receiving spin liquid appropriate to produce a quantum computer.
