Self-testing in a constrained prepare-measure scenario sans assuming quantum dimension
Ritesh K. Singh, Souradeep Sasmal, S. Nautiyal +1
We present a device-independent (DI) self-testing protocol in a constrained prepare-measure scenario, based on the bit parity-oblivious multiplexing (POM) task. In this scenari…
