Bosonic Cyclic Codes: Trading Stabilizers for Gaussian Non-Clifford Phase Gates
Owen C. Wetherbee, Yijia Xu, Victor V. Albert +2
Bosonic codes offer hardware-efficient approaches to quantum error correction, with the best encodings offering effective protection of idle quantum information against loss and de…
Chutes and Ladders: Dynamical Automorphisms via the ZX-Calculus
Alexander Frei, Sascha Zakaib-Bernier, Zachary Mann +2
The ZX-calculus is a powerful graphical language for manipulating quantum circuits, which has recently found many applications in quantum error correction. We extend this language…
Calderbank-Shor-Steane codes on group-valued qudits
Ben T. McDonough, Jian-Hao Zhang, Victor V. Albert +1
Calderbank-Shor-Steane (CSS) codes are a versatile quantum error-correcting family built out of commuting - and -type checks. We introduce CSS-like codes on -valued qudits…
Continuous-variable designs and design-based shadow tomography from random lattices
Jonathan Conrad, Joseph T. Iosue, Ansgar G. Burchards +1
We investigate state designs for continuous-variable quantum systems using the aid of lattice-like quantum states. These are code states of Gottesman-Kitaev-Preskill (GKP) codes. W…
