One big problem holding up the development of quantum computing is build materials . But there might be a solution , and it awesomely involves nitrogen - tincture diamond nanocrystals .
Quantum information processing system theoretically solve by using qubits ( short for quantum bits ) , which can rely on quantum mechanically skillful principle to hold multiple value simultaneously . This ability makes quantum computers unimaginably faster than their atomic number 14 counterparts when dealing with certain type of problems . alas , the only candidates from which to make qubits , like individual atoms and semiconducting quantum dots , require temperature far below zero in decree to work .
There might now be a room temperature solution , accord to a squad of scientists at China ’s Wuhan Institute of Physics and Mathematics , the Chinese Academy of Sciences , and the University of Science and Technology of China . They say that something called baseball diamond nitrogen emptiness materials , or NV materials , could do the task .
To create such a material , you first need to make an super fine baseball diamond film – essentially , a super belittled diamond crystal – with a “ molecule ” at its shopping mall . This speck is composed of a atomic number 7 mote and a vacancy , a region within the watch glass where there are no atom at all . This musical arrangement could then operate as a qubit , appropriate for information to exist in superpositions and signal the dawn of quantum computation .
The material difficulty would be pair the diamond - NV centers together , a cognitive process that would require multiple acts of quantum entanglement . Indeed , a vast act of these NV textile would need to be bring together to achieve the complexness of something like a quantum figurer , and that make up a major challenge . Still , it ’s exciting that this is within the land of current skill at all , and it ’s a discovery just to reduce the problem from theoretic impossibility to practical incubus .
