摘要原文
Quantum transducers convert quantum signals from one carrier to another through hybrid interfaces of physical systems. For a quantum transducer between two bosonic modes, direct quantum transduction without shared entanglement or classical communication typically requires a conversion efficiency exceeding 0.5 which is challenging for current experiments. We propose the passive environment-assisted quantum transduction to overcome this stringent requirement. Without internal losses, the quantum transducer realizes a beam splitter unitary between two modes. The added noises to the transduction process from mode 1 to mode 2 is determined by the initial state of mode 2, which can be engineered to enhance the transduction performance. We find that by choosing the ideal Gottesman-Kitaev-Preskill (GKP) states as the initial states of both modes, perfect quantum transduction can be achieved at arbitrarily low conversion efficiencies. In practice, it is crucial to also consider the finite energy constraints and high fidelity quantum transduction remains achievable with GKP states at the few-photon level.
