Abstract

Two identical squeezed coherent states at the input ports of a 50% absorbing beam splitter do not show coherent perfect absorption (CPA). All coherence is lost, though, since at the output ports entangled squeezed vacuum states emerge. Remarkably, this output state is a pure state, although produced by a lossy device. Therefore this CPA gate could become a new tool for continuous-variable quantum state preparation. Moreover, for graphene multilayers engineered for CPA, we discuss the effects of interlayer separation.
