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…
Efficiently architecting VQAs: Expressibility--Trainability--Resources Pareto-Optimality
Rodrigo M. Sanz, Andreu Angles-Castillo, Eduard Alarcon +1
Ansatz selection is a key factor in the performance of variational quantum algorithms (VQAs). While much of the state-of-the-art still relies on heuristic choices, an inadequate ci…
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…
Exponential improvement in benchmarking multiphoton interference
Rodrigo M. Sanz, Emilio Annoni, Stephen C. Wein +4
Several photonic quantum technologies rely on the ability to generate multiple indistinguishable photons. Benchmarking the level of indistinguishability of these photons is essenti…
Enabling Technologies for Scalable Superconducting Quantum Computing
Xanthe Croot, Kasra Nowrouzi, Christopher Spitzer +21
Experiments with superconducting quantum processors have successfully demonstrated the basic functions needed for quantum computation and evidence of utility, albeit without a siza…
Lattice Surgery Aware Resource Analysis for the Mapping and Scheduling of Quantum Circuits for Scalable Modular Architectures
Batuhan Keskin, Cameron Afradi, Sylvain Lovis +4
Quantum computing platforms are evolving to a point where placing high numbers of qubits into a single core comes with certain difficulties such as fidelity, crosstalk, and high po…
