Ion Beams Create Chains of Closely Coupled Qubits

Ion Beams Qubits Diamond
Ion beams can create chains of closely coupled quantum bits (qubits) based on nitrogen-vacancy “color centers” in diamond for use in quantum computing hardware. The honeycomb pattern in the photo shows the difference between areas exposed to the beam (darker) and masked-off areas. Results indicate it should be possible to create 10,000 coupled qubits over a distance of about the width of a human hair, an unrivaled number and density of qubits.

Achieving the immense promise of quantum computing requires new developments at every level, including the computing hardware itself.  A Lawrence Berkeley National Laboratory (Berkeley Lab)-led international team of...
