A group of experts from the University of Southern California, managed to build a quantum computer in diamond. Such a case, by their properties, can protect quantum computations from decoherence, noise, preventing proper data transfer. Although the size of device is very small, it have shown the feasibility of establishing solid-state quantum devices. They are much more stable in operation and easily scalable.
Instead of electrons to transfer the quantum state , the researchers used nitrogen nucleus, located inside the diamond as an impurity. Qubits have turned out slower, but the time of decoherence has significantly increased, up to several milliseconds, which is a significant achievement, according to Prof. Daniel Lidar (Daniel Lidar). Due to a more stable qubits and diamond shell, scientists were able to achieve the correct performance of operations by 95%, which, of course, is not enough for practical use. Related Products :
