Distillation of supersinglet states
Saeed Ahmad, Shuang Li, Jonathan Raghoonanan +3
We introduce an entanglement distillation (purification) protocol for supersinglet states composed of N qubits. The supersinglet state we target is a total spin zero state with zer…

Ultrahigh threshold nonstabilizer nonlinear quantum error correcting code
Maga Grafe, Kaixuan Zhou, Zaman Tekin +5
We introduce a novel type of quantum error correcting code, called the spinor code, based on spaces defined by total spin. The code is a nonstabilizer code, and is also a nonlinear…
