📌 Key Points
High-fidelity collisional quantum gates with fermionic atoms
A composite pair-exchange gate using fermionic atoms in an optical superlattice has been developed.
The gate demonstrates high fidelities and long Bell-state lifetimes.
This advancement is a significant step towards achieving a fully digital fermionic quantum computer.
The experiment utilizes a degenerate Fermi gas of 6Li atoms in a balanced mixture of two hyperfine states.
The two hyperfine states represent the two spin states necessary for quantum computation.
