Uses the electron and nuclear spins of individual atoms in silicon as quantum information carriers, developing the control and readout methods needed to make those qubits usable.
UNSW SydneyarXivMorello’s contribution centers on making a single atom in silicon behave as a controllable information system. His group’s electron-spin work established practical readout and control, followed by nuclear-spin demonstrations that exploited a different part of the same atom. This gives silicon quantum computing both processing and memory possibilities. The research is significant because a qubit needs preparation, operations and measurement together; long coherence alone is insufficient. The cited results remain specific experimental demonstrations rather than evidence of a completed large-scale processor.
UNSW SydneyarXivWhat changes when quantum information uses more than two levels?
A qubit uses two states to encode quantum information. Systems with more available levels invite a different question: which states can be controlled and used together? More levels alone do not establish a proportionally more useful computer; the operations, errors and encoding still matter. [1]
Andrea Morello is listed on the organising committee for Beyond Qubits 2026, taking place in Sydney on 1–3 December. The meeting brings together research on qudits and other approaches beyond familiar qubit encodings, including control, error correction and algorithms. [1]
This is a dated contribution to a research community, distinct from a new experimental result. The event provides a route into the discussion. Its organising role remains part of the historical record after the meeting, without implying that Morello alone invented the approaches being discussed. [1]
Keep asking: What can the additional levels do under the available controls and error model?
