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…
An Analytical Approach to Design Space Exploration for Cavity-Mediated Quantum State Transfer in Multi-core Architectures
Biel Pons Zaragoza, Junaid Khan, Rohit Sarma Sarkar +4
In multi-core quantum computing architectures, waveguide-mediated interconnects are essential for facilitating fast, high-fidelity quantum state transfer between qubits located in…
Assessing the Impact of Low Resolution Control Electronics on Quantum Neural Network Performance
Rupayan Bhattacharjee, Rohit Sarma Sarkar, Sergi Abadal +2
Scaling quantum computers requires tight integration of cryogenic control electronics with quantum processors, where Digital-to-Analog Converters (DACs) face severe power and area…
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…
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…
