Energy efficiency of quantum computers
Miquel Carrasco-Codina, Pau Escofet, Paul Hilaire +13
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 defin…
Synthesizing an Optimal Spin Qubit Shuttling Bus Architecture for the Surface Code
Pau Escofet, Eduard Alarcón, Sergi Abadal +4
As quantum computers scale toward millions of physical qubits, it becomes essential to robustly encode individual logical qubits to ensure fault tolerance under realistic noise. A…
Quantum Circuit Pruning: Improving Fidelity via Compilation-Aware Circuit Approximation
Pau Escofet, Santiago Rodrigo, Rohit Sarma Sarkar +3
This work presents a routing-aware pruning strategy for quantum circuits executed on Noisy Intermediate-Scale Quantum (NISQ) devices. We propose a method to remove parametric contr…
Assessing the Role of Communication in Modular Multi-Core Quantum Systems
Maurizio Palesi, Enrico Russo, Giuseppe Ascia +8
The scalability of quantum computing is constrained by the physical and architectural limitations of monolithic quantum processors. Modular multi-core quantum architectures, which…
Accurate and Scalable Simulation of Cavity-Based Networks in Modular Quantum Architectures
Sahar Ben Rached, Zezhou Sun, Guilu Long +4
Cavity-mediated interconnects are a promising platform for scaling modular quantum computers by enabling high-fidelity inter-chip quantum state transmission and entanglement genera…
Modeling Quantum Links for the Exploration of Distributed Quantum Computing Systems
Sahar Ben Rached, Zezhou Sun, Junaid Khan +5
Quantum computing offers the potential to solve certain complex problems, yet, scaling monolithic processors remains a major challenge. Modular and distributed architectures are pr…
