Tunable Diamond String May Hold Key to Quantum Memory

Caption

Electrodes stretch diamond strings to increase the frequency of atomic vibrations to which an electron is sensitive, just like tightening a guitar string increases the frequency or pitch of the string. The tension quiets a qubit's environment and improves memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip.
