Most materials being considered for quantum technology can hold a stable quantum state only when chilled to extreme temperatures. Diamond-based materials can work at room temperature, but their usefulness depends on defects in the crystal that have been difficult and computationally demanding to simulate.
At the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), staff research scientist Mark Martirez has developed a far faster way to calculate how those defects respond to light and microwave pulses. The approach has identified promising boron- and oxygen-based defects that could serve as qubits, the basic information-processing units of quantum computers and sensors. The research was recently published in ACS Central Science and has already attracted attention from other experts in the field.
