Simulation of Quantum Transduction Strategies for Quantum Networks

Laura d'Avossa, Caitao Zhan, Joaquin Chung, Rajkumar Kettimuthu, Angela Sara Cacciapuoti, Marcello Caleffi

TL;DR

This paper extends SeQUeNCe, an opensource, discrete-event simulator of quantum networks, with a quantum transduction component along with auxiliary hardware device models and protocols, and explores two strategies for transmitting quantum information between superconducting nodes via optical channels with a focus on the impact of quantum transduction on the transmission process.

Abstract

The Quantum Internet would likely be composed of diverse qubit technologies that interact through a heterogeneous quantum network. Thus, quantum transduction has been identified as a key enabler of the Quantum Internet. To better study heterogeneous quantum networks, the integration of a quantum transducer component into quantum network simulators has become crucial. In this paper, we extend SeQUeNCe, an open-source, discrete-event simulator of quantum networks, with a quantum transduction component along with auxiliary hardware device models and protocols. Moreover, we explore two strategies for transmitting quantum information between superconducting nodes via optical channels, with a focus on the impact of quantum transduction on the transmission process. The performance of these strategies is analyzed and compared through simulations conducted using SeQUeNCe. Our results align with theoretical predictions, offering simulation-based validation of the strategies and providing a path to accurate, larger-scale simulations of heterogeneous quantum networks.

  • Figure 2: Different functionalities of a quantum transducer: (a) up-conversion from microwave to optical, (b) down-conversion from optical to microwave, and (c) hybrid EPR pair generation. Subscripts of the quantum state indicate the frequency of the photon.
  • Figure 3: DQT system setup.
  • Figure 4: DQT high-level design. Attributes can be manually set while methods are called within the protocols.
  • Figure 5: EQT system setup. Shaded blue transmons represent the ancilla qubits used for hybrid entanglement generation, while the non-shaded transmon represents the qubit that stores the quantum information to be teleported. Classical channels are omitted to maintain clarity.
