Sequential generalized measurements: Asymptotics, typicality and emergent projective measurements
Wen-Long Ma, Shu-Shen Li, Ren-Bao Liu
The relation between projective measurements and generalized quantum measurements is a fundamental problem in quantum physics, and clarifying this issue is also important to quantu…
Algebraic structure of path-independent quantum control
Wen-Long Ma, Shu-Shen Li, Liang Jiang
Path-independent (PI) quantum control has recently been proposed to integrate quantum error correction and quantum control [Phys. Rev. Lett. 125, 110503 (2020)], achieving fault-to…
Atomic-scale positioning of single spins via multiple nitrogen-vacancy centers
Wen-Long Ma, Shu-Shen Li, Geng-Yu Cao +1
We present a scheme of positioning a single electron spin with sub-nanometer resolution through multiple nitrogen-vacancy centers in diamond. With unwanted noise suppressed by dyna…
The classical nature of nuclear spin noise near clock transitions of Bi donors in silicon
Wen-Long Ma, Gary Wolfowicz, Shu-Shen Li +2
Whether a quantum bath can be approximated as classical noise is a fundamental issue in central spin decoherence and also of practical importance in designing noise-resilient quant…
Decoherence of a quantum system coupled to an XY spin chain: Role of the initial state of the spin chain
Zi-Gang Yuan, Ping Zhang, Shu-Shen Li
We study the decoherence of a coupled quantum system consisting of a central spin and its correlated environment described by a general spin-chain model. We make it clear that…
The Quantification of Quantum Nonlocality by Characteristic Function
Wei Wen, Shu-Shen Li
Quantum nonlocal correlation (QNC) is thought to be more general than quantum entanglement correlation, but the strength of it has not been well defined. We propose a way to measur…
