What are spin qubits?

IBM Research · 2 months ago · 28

IBM announced it will acquire HRL Laboratories to expand its quantum computing capabilities, particularly gaining access to HRL's expertise in silicon-spin qubit technology. HRL recently demonstrated a silicon-spin quantum computer with 54 quantum dots capable of functioning as up to 18 qubits, using exchange-only qubit architecture with three electrons per qubit. The acquisition will strengthen IBM's long-term plans to deliver useful quantum computing while adding quantum sensing and quantum networking capabilities to complement its existing superconducting qubit research.
