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…
Transmitter Noise Propagation in Millimeter-Wave and Sub-Terahertz: From Limits to Design Guidelines
Mahir Burak Usta, Didem Aydogan, Evgenii Vinogradov +4
This paper presents a comprehensive link budget analysis for millimeter wave (mm-Wave) and sub-Terahertz (sub-THz) communication systems with primary focus on transmitter (TX) nois…
Channel-Aware Behavioral Power Modeling of CMOS OOK Transceivers for Wireless Network-on-Chip Systems
Mohammad Shahmoradi, Ahmet YelboÄa, Eduard Alarcón +2
Wireless Network-on-Chip (WNoC) systems enable low-latency communication in many-core platforms through short-range wireless links. However, the power consumption of integrated tra…
Cryo-CMOS Antenna for Wireless Communications within a Quantum Computer Cryostat
Viviana Centritto, Ama Bandara, Heqi Deng +4
Scaling quantum computers from a few qubits to large numbers remains one of the critical challenges in realizing practical quantum advantage. Multi-core quantum architectures have…
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…
