Christopher Monroe

Develops trapped-ion quantum computers and photonic interconnects, linking precise control of individual atomic qubits with architectures that connect separate quantum processors into larger systems.

Monroe’s work addresses both computation inside an ion processor and communication between processors. The reviewed experiments show why those tasks belong together: mid-circuit measurement must avoid damaging stored data, while modular machines need entanglement across physically separated memories. His Duke group’s recent papers offer concrete examples of each. These are specific experimental building blocks for scalable systems, rather than evidence that a useful, fully fault-tolerant machine has already been delivered.
