Closing the Detection Loophole in Bell Experiments Using Qudits
Closing the Detection Loophole in Bell Experiments Using Qudits
We show that the detection efficiencies required for closing the detection loophole in Bell tests can be significantly lowered using quantum systems of dimension larger than two. We introduce a series of asymmetric Bell tests for which an efficiency arbitrarily close to 1/N can be tolerated using N-dimensional systems, and …
