Sensors and probes

Sensors and probes are molecules that report the presence of specific ions, molecules or molecular events in vitro or in cells by communicating a measurable signal, often a light-based readout. They may function through selective interaction or attachment to a molecule of interest or undergo conformational changes.

    A fast, high-fidelity two-qubit exchange gate between phosphorus donor electron spin qubits in silicon is demonstrated by creating a tunable exchange interaction between two electrons bound to phosphorus atom qubits.

    Fluctuating nuclear spin ensembles are a significant decoherence mechanism for solid-state spin qubits. Here the authors introduce an approach to controlling and extending the coherence of a nuclear spin bath around self-assembled quantum dots and gain insight into the many-body dynamics.

    Random sequences of unitary gate operations on an exchange-only qubit encoded in three physical electron qubits are performed using only voltage pulses and exhibit an average total error of 0.35%, where half of the error originates from leakage out of the computational subspace caused by interactions with substrate nuclear spins.
