(InsideScience) Researchers at the Delft University of Technology have created a diamond-based quantum memory device that can retain a quantum state for more than a minute, making it the most stable quantum memory device of its kind. “Quantum states are very fragile. They can be lost very easily, and you can’t copy them,” said Conor Bradley, a physicist who is a member of the team. “One of the goals for our quantum bits is that they can retain a property called coherence for a long time.”

Potential for Diamonds to Be Used in Quantum Computers & Quantum Communications
The potential for diamonds to be used in quantum computers has prompted scientists to try to grow the perfectly flawed diamond, building it atom by atom with holes and defects located exactly where they should be, instead of leaving it up to nature and chance. The ability for diamond qubits to interact with light also makes them more suitable for certain applications such as long-range quantum communications, which are mostly done using lasers.
