Neural-Network Inverse Design of SRF Cavities and Transmons for Bosonic Quantum Computation

Joseph Yaker, Jovan Markovic, Alessandro Reineri +2

Three-dimensional superconducting radio-frequency (SRF) cavities provide exceptionally long-lived electromagnetic modes and, when coupled to nonlinear elements such as transmon qub…

Efficient Floating-Point Arithmetic on Fault-Tolerant Quantum Computers

José E. Cruz Serrallés, Oluwadara Ogunkoya, Do{g}a Murat Kürkçüo{g}lu +5

We propose a novel floating-point encoding scheme that builds on prior work involving fixed-point encodings. We encode floating-point numbers using Two's Complement fixed-point man…
