Ancilla assisted Discrete Time Crystals in Non-interacting Spin Systems
Jianpei Geng, Vadim Vorobyov, Durga Dasari +1
We show here through experiments and exact analytical models the emergence of discrete time translation symmetry breaking in non-interacting systems. These time-periodic structures…
Experimental dissipative quantum sensing
Yijin Xie, Jianpei Geng, Huiyao Yu +3
Quantum sensing utilizes quantum systems as sensors to capture weak signal, and provides new opportunities in nowadays science and technology. The strongest adversary in quantum se…
Observation of parity-time symmetry breaking in a single spin system
Yang Wu, Wenqiang Liu, Jianpei Geng +5
A fundamental axiom of quantum mechanics requires the Hamiltonians to be Hermitian which guarantees real eigen-energies and probability conservation. However, a class of non-Hermit…
Quantum state tomography of a single electron spin in diamond with Wigner reconstruction
Bing Chen, Jianpei Geng, Feifei Zhou +3
We present the experimental reconstruction of the Wigner function of an individual electronic spin qubit associated with a nitrogen-vacancy (NV) center in diamond at room temperatu…
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…
Constraints on a Spin-Dependent Exotic Interaction between Electrons with Single Electron Spin Quantum Sensors
Xing Rong, Man Jiao, Jianpei Geng +6
A new laboratory bound on the axial-vector mediated interaction between electron spins at micrometer scale is established with single nitrogen-vacancy (NV) centers in diamond. A si…
