Generating Fock state exceeding 10000 excitations with near unit fidelity by adaptive generalized-parity measurement
Chen-yi Zhang, Jun Jing
Fock states are fundamental quantum states with a precisely defined integer number of excitations, serving as the core basis for describing bosonic modes. Large Fock states provide…
Efficient nonclassical state preparation via generalized parity measurement
Chen-yi Zhang, Jun Jing
Nonclassical states of bosonic modes, especially the large number states, are valuable resources for quantum information processing and quantum metrology. It is however intricate t…
Dissipative qutrit-mediated stable charging
Chen-yi Zhang, Jun Jing
In this work, we propose a stable charging scheme mediated by a three-level system (qutrit), which renders a unidirectional energy flow from an external power source to an -…
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…
