Vučković’s quantum research group able to read qubit’s spin state in a single shot
The high-accuracy, single-shot readout of the signal with reliable spin control is a first for tin-vacancy qubits.

Stanford collaborators at the Q-NEXT quantum center amp up the signal from tin atoms embedded in diamond, opening possibilities for quantum networking.
The future of tin-based qubits is brighter thanks to breakthrough work by Stanford University researchers supported through a quantum research center led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory.
Qubits are the fundamental carriers of quantum information, and scientists worldwide are engineering atoms to create reliable, long-lived qubits for processing quantum data. Quantum engineering is expected to accelerate advances in areas as diverse as medicine and finance.
The Stanford team achieved their milestone on a type of qubit known as a tin vacancy center in diamond: replace two of diamond’s carbon atoms with one atom of tin and voila! A tin vacancy qubit is born.
