Home develops trapped-ion control and oscillator encodings, helping demonstrate a logical grid-state qubit and correction cycles that prolong information stored in an ion’s motion.
Home’s experimental work explores how a single oscillator can carry a protected logical qubit. His collaborations first prepared and controlled grid states in the motion of a trapped calcium ion, then demonstrated correction of small shifts in position and momentum. This connects a mathematical encoding to the physical operations needed to maintain it. The results are significant steps in quantum control and error correction, with their scope limited to the particular encoded systems and procedures tested.
Co-proposed quantum computing with electron spins in quantum dots and helped develop the theoretical and institutional foundations of semiconductor-spin quantum information processing.
Loss helped turn the spin of a confined electron into a detailed proposal for a quantum-computing building block. The shared Loss–DiVincenzo architecture specifies how spins could store information and interact to perform gates, while later work examines the obstacles between that proposal and an operating machine. His Basel research and participation in NCCR SPIN connect the theoretical program to a broader semiconductor-qubit effort. Inclusion recognizes an architectural contribution and sustained research activity, without assigning him every subsequent experimental result in the field.
