Universal quantum control over bosonic network
Zhu-yao Jin, Jun Jing
Perfect transfer of {\em unknown} states across distinct nodes is a basic function in bosonic quantum networks. Here we develop a general theory to construct an -node bosonic ne…
Universal quantum control over Majorana zero modes
Zhu-yao Jin, Jun Jing
Majorana zero mode (MZM) exhibits inherent resilience to local parametric fluctuations, due to the topological protection mechanism in the non-Abelian braiding statistics of the an…
Universal quantum control by non-Hermitian Hamiltonian
Zhu-yao Jin, Jun Jing
Conventional manipulations over quantum systems for such as coherent population trapping and unidirectional transfer focus on Hamiltonian engineering while regarding the system's m…
Achieving the Heisenberg limit of metrology via measurement on an ancillary qubit
Peng Chen, Jun Jing
In the scenario of the probe-ancilla interaction, we propose a quantum metrology protocol by the unconditional measurement on the ancillary qubit after an optimized period of joint…
Preparing Greenberger-Horne-Zeilinger state on ground levels of neutral atoms
Zhu-yao Jin, Jun Jing
We propose a scalable protocol in the Rydberg atomic system to generate the Greenberger-Horne-Zeilinger (GHZ) states, where the qubits are encoded on the hyperfine ground levels. O…
Universal quantum control with dynamical correction
Zhu-yao Jin, Jun Jing
Error correction is generally demanded in large-scale quantum information processing and quantum computation. We provide here a universal and realtime control strategy to dynamical…
