A Quantum Gate Chooses Its Recipient Later
A two-qudit entangling gate can be split among candidate nodes before one later key release selects the only node allowed to use it.
Summary
A two-qudit entangling gate can be split among candidate nodes before one later key release selects the only node allowed to use it.
The protocol encrypts half of a Bell pair into shares and preserves secrecy against fewer than all candidate nodes. The selected node can apply the exact non-local gate; the key cannot be reused.
Why it matters
A two-qudit entangling gate can be split among candidate nodes before one later key release selects the only node allowed to use it.
Limits and context
- The selected node can apply the exact non-local gate; the key cannot be reused.
