In this work we introduce two code families, which we call the heavy-hexagon code and the
heavy-square code. Both code families are implemented by assigning physical data and …

The unique features of quantum theory offer a powerful new paradigm for information
processing. Translating these mathematical abstractions into useful algorithms and …

The Gottesman-Kitaev-Preskill (GKP) code was proposed in 2001 by Daniel Gottesman,
Alexei Kitaev, and John Preskill as a way to encode a qubit in an oscillator. The GKP …

Building a quantum computer that surpasses the computational power of its classical
counterpart is a great engineering challenge. Quantum software optimizations can provide …

Bosonic quantum error correction is a viable option for realizing error-corrected quantum
