Two-Phonon Resonance Drives Multicomponent Mechanical Cat States
Nuo Wang, Haoyang Zhang, Yu Tian +2
Using quadratic optomechanical coupling to prepare high-purity mechanical cat states is not feasible as its strength is several orders weaker than linear optomechanical coupling. H…
Direct Readout of Nitrogen-Vacancy Hybrid-Spin Quantum Register in Diamond by Photon Arrival Time Analysis
Jingyan He, Yu Tian, Zhiyi Hu +4
Quantum state readout plays a pivotal role in quantum technologies, spanning applications in sensing, computation, and secure communication. In this work, we introduce a new approa…
Preserving Entanglement in a Solid-Spin System Using Quantum Autoencoders
Feifei Zhou, Yu Tian, Yumeng Song +6
Entanglement, as a key resource for modern quantum technologies, is extremely fragile due to the decoherence. Here, we show that a quantum autoencoder, which is trained to compress…
Pulse-width-induced polarization enhancement of optically-pumped N-V electron spin in diamond
Yumeng Song, Yu Tian, Zhiyi Hu +7
The nitrogen-vacancy (N-V) center in diamond is a widely-used platform for quantum information processing and metrology. The electron-spin state of N-V center could be initialized…
Dynamically Polarizing Spin Register of NV Centers in Diamond using Chopped Laser Pulses
Nanyang Xu, Yu Tian, Bing Chen +4
Nuclear spins nearby nitrogen-vacancy (NV) centers in diamond are excellent quantum memory for quantum computing and quantum sensing, but are difficult to be initialized due to the…
Wavelet-based fast time-resolved magnetic sensing with electronic spins in diamond
Nanyang Xu, Fengjian Jiang, Yu Tian +6
Time-resolved magnetic sensing is of great importance from fundamental studies to applications in physical and biological sciences. Recently the nitrogen-vacancy (NV) defect center…
