From Liouville equation to universal quantum control: A study of generating ultra highly squeezed states
Zhu-yao Jin, J. Q. You, Jun Jing
We find that the seemingly disparate control approaches for classical and quantum continuous-variable systems can be unified via differential manifolds of the ancillary representat…
Precision limit under weak coupling with an ancillary qubit
Peng Chen, Jun Jing
We propose a measurement-based quantum metrology protocol in a composite model, where the probe system (a spin ensemble) is coupled to an ancillary two-level system (qubit) with a…
Universal quantum control over non-Hermitian continuous-variable systems
Zhu-yao Jin, Jun Jing
Current studies about the continuous-variable systems in non-Hermitian quantum mechanics heavily revolved around the singularities in the eigenspectrum by mimicking their discrete-…
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…
Entangling distant systems via universal nonadiabatic passage
Zhu-yao Jin, Jun Jing
In this paper, we derive universal nonadiabatic passages in a general -dimensional discrete system, where and denote the degrees of freedom for the assistant and worki…
Generating Fock-state superpositions from coherent states by selective measurement
Chen-yi Zhang, Jun Jing
Fock states and their superpositions are exotic testbeds for nonclassical physics and valuable resources for quantum technologies. We provide a simple protocol for the quantum meas…
Realizing a mechanical dynamical Casimir effect with a low-frequency oscillator
Tian-hao Jiang, Jun Jing
We propose to realize a mechanical dynamical Casimir effect (MDCE) in a hybrid optomechanical system consisting of a cavity mode, a low-frequency mechanical oscillator, and a two-l…
Universal perspective on nonadiabatic quantum control
Zhu-yao Jin, Jun Jing
A stable and fast path linking two arbitrary states of a quantum system is generally required for state-engineering protocols, such as stimulated Raman adiabatic passage, shortcuts…
Qubit-assisted quantum metrology under a time-reversal strategy
Peng Chen, Jun Jing
We propose a quantum metrology protocol based on a two-step joint evolution of the probe system and an ancillary qubit and quantum measurement. With a proper initial state of the a…
Generating magnon Bell states via parity measurement
Jia-shun Yan, Jun Jing
We propose a scheme to entangle two magnon modes based on parity measurement. In particular, we consider a system that two yttrium-iron-garnet spheres are coupled to a -type sup…
Stabilizing a single-magnon state by optimizing magnon blockade
Zhu-yao Jin, Jun Jing
A stable and high-quality single-magnon state is desired by the single-magnon source for quantum information application with a macroscopic spin system. We consider a hybrid system…
