Developing the field of quantum information science (QIS) hinges upon designing viable qubits, the smallest unit in quantum computing. One approach to creating qubits is introducing paramagnetic defects into semiconductors or insulators. This class of qubits has seen success in the form of nitrogen-vacancy centers in diamond, divacancy defects in SiC, and P doped into Si. These materials feature paramagnetic defects in a low nuclear spin environment to reduce the impact of nuclear spin on… Expand

Ultralong spin coherence time in isotopically engineered diamond.
Here, it is demonstrated the synthesis and application of ultrapure isotopically controlled single-crystal chemical vapour deposition (CVD) diamond with a remarkably low concentration of paramagnetic impurities, and single electron spins show the longest room-temperature spin dephasing times ever observed in solid-state systems.

Rare-earth solid-state qubits.
A new family of spin qubits based on rare-earth ions demonstrates values of τ2 and QM at 2.5 K, which suggests that rare- earth qubits may, in principle, be suitable for scalable quantum information processing at 4He temperatures. Expand

• 2016
A way of enhancing coherence in solid-state molecular spin qubits without resorting to extreme dilution is presented, based on the design of molecular structures with crystal field ground states possessing large tunnelling gaps that give rise to optimal operating points, or atomic clock transitions, at which the quantum spin dynamics become protected against dipolar decoherence.
