Exploring a Double Full-Stack Communications-Enabled Architecture for Multi-Core Quantum Computers

2020 · arXiv (Cornell University)

Being a very promising technology, with impressive advances in the recent years, it is still unclear how quantum computing will scale to satisfy the requirements of its most powerful applications. Although continued progress in the …

Revisiting the Mapping of Quantum Circuits: Entering the Multi-Core Era

2024 · arXiv (Cornell University)

Quantum computing represents a paradigm shift in computation, offering the potential to solve complex problems intractable for classical computers. Although current quantum processors already consist of a few hundred of qubits, their scalability remains a …

Characterizing the Inter-Core Qubit Traffic in Large-Scale Quantum Modular Architectures

2025 · IEEE Access

Modular quantum processor architectures are envisioned as a promising solution for the scalability of quantum computing systems beyond the Noisy Intermediate Scale Quantum (NISQ) era. Based upon interconnecting tens to hundreds of quantum processors (i.e …

Energy efficiency of quantum computers

2026 · HAL (Le Centre pour la Communication Scientifique Directe)

How much energy does a quantum computer consume? Are they more efficient than their classical counterparts? In this work, we make a step towards answering these questions. We define the energy efficiency of a quantum …
