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…
Preparing squeezed, cat and GKP states with parity measurements
Zhiyuan Lin, Sen Li, Jingyan Feng +4
Bosonic modes constitute a central resource in a wide range of quantum technologies, providing long-lived degrees of freedom for the storage, processing, and transduction of quantu…
Phase assumption-free multiparty quantum clock synchronization
Hatim A. Oujaa, Qiao Liu, Ebubechukwu O. Ilo-Okeke +3
We investigate methods to broadcast timing information from a central clock to all other clocks by the use of multipartite entanglement. This task is a necessary step in establishi…
Quantum teleportation of cat states with binary-outcome measurements
Jingyan Feng, Mohan Zhang, Matteo Fadel +1
We propose a teleportation protocol involving beam splitting operations and binary-outcome measurements, such as parity measurements. These operations have a straightforward implem…
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…
Macroscopic quantum teleportation with ensembles of qubits
Manish Chaudhary, Zhiyuan Lin, Shuang Li +4
We develop methods for performing quantum teleportation of the total spin variables of an unknown state, using quantum nondemolition measurements, spin projection measurements, and…
