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…
Pre-emptive parametric kill switch for evaporative atomic sources in vacuum
Shuang Li, Zhiyuan Lin, Sen Li +7
A robust pre-emptive kill switch for cold atom experiments is introduced to significantly reduce costly system reassembly or replacement. The design incorporates upper (alarm) and…
Neutral atom entangling gate in the ultrastrong coupling regime
Ebubechukwu O. Ilo-Okeke, Tongzhou Wang, Valentin Ivannikov +1
We propose a method to deterministically entangle qubits or ensembles of qubits interacting with a shared bosonic mode in the ultrastrong coupling regime. We show that the resultin…
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…
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…
