Pulsed characteristic-function measurement of a thermalizing harmonic oscillator
Ralf Betzholz, Yu Liu, Jianming Cai
We present a method for the direct measurement of the Wigner characteristic function of a thermalizing harmonic oscillator that is completely inaccessible for control or measuremen…
Quantum optimal control using phase-modulated driving fields
Jiazhao Tian, Haibin Liu, Yu Liu +5
Quantum optimal control represents a powerful technique to enhance the performance of quantum experiments by engineering the controllable parameters of the Hamiltonian. However, th…
Complete Quantum-State Tomography with a Local Random Field
Pengcheng Yang, Min Yu, Ralf Betzholz +2
Single-qubit measurements are typically insufficient for inferring arbitrary quantum states of a multi-qubit system. We show that if the system can be fully controlled by driving a…
Nanotube Double Quantum Dot Spin Transducer for Scalable Quantum Information Processing
Wanlu Song, Tianyi Du, Haibin Liu +2
One of the key challenges for the implementation of scalable quantum information processing is the design of scalable architectures that support coherent interaction and entangleme…
Pulsed Quantum-State Reconstruction of Dark Systems
Yu Liu, Jiazhao Tian, Ralf Betzholz +1
We propose a novel strategy to reconstruct the quantum state of dark systems, i.e., degrees of freedom that are not directly accessible for measurement or control. Our scheme relie…
Scalable nuclear-spin entanglement mediated by a mechanical oscillator
Puhao Cao, Ralf Betzholz, Jianming Cai
We propose a solid-state hybrid platform based on an array of implanted nitrogen-vacancy (NV) centers in diamond magnetically coupled to a mechanical oscillator. The mechanical osc…
