Quantum correlation enhanced weak field detection in optomechanical system
Wen-Zhao Zhang, Li-Bo Chen, Jiong Cheng +1
We propose a theoretical scheme to enhance the signal-to-noise ratio in ultrasensitive detection with the help of quantum correlation. By introducing the auxiliary oscillator and t…
Weak measurement amplification in optomechanics via a squeezed coherent state pointer
Gang Li, Li-Bo Chen, Xiu-Min Lin +1
We present a scheme for achieving amplification of the displacement of the mirror in optomechanical cavity using single-photon postselection where the mirror is initially prepared…
Precision metrology of weak measurement with thermal state pointer
Gang Li, Li-Bo Chen, Tao Wang +2
Quantum metrology is being gradually studied for weak measurement systems. For weak measurement systems with thermal state pointer, we find that in the displacement space correspon…
Heralded entanglement of two distant quantum dot spins via optical interference
Li-Bo Chen, Wen Yang, Zhang-Qi Yin
We present a proposal for heralded entanglement between two quantum dots via Hong--Ou--Mandel effect. Each of the quantum dots, drived off-resonance by two lasers, can be entangled…
All-optical controlled phase gate in quantum dot molecules
Li-Bo Chen, Wen Yang
We propose a two-qubit optically controlled phase gate in quantum dot molecules via adiabatic passage and hole tunneling. Our proposal combines the merits of the current generation…
Generating atomic multi-dimensional entangled states under large atom-cavity detuning
Peng Shi, Li-Bo Chen, Wen-Dong Li +3
We propose a scheme to deterministically generate atomic two-dimensional and three-dimensional entangled states by passing two 87Rb atoms through a high-Q bi-mode cavity alternatel…
Generation of three-dimensional entangled states between a single atom and a Bose-Einstein Condensate via adiabatic passage
Li-Bo Chen, Peng Shi, Chun-Hong Zheng +1
We propose a robust scheme to prepare three-dimensional entanglement states between a single atom and a Bose-Einstein Condensate (BEC) via stimulated Raman adiabatic passage (STIRA…
Optically controlled phase gate for two spin qubits in coupled quantum dots
Li-Bo Chen, L. J. Sham, Edo Waks
We present a feasible scheme for performing an optically controlled phase gate between two conduction electron spin qubits in adjacent self assembled quantum dots. Interaction betw…
Generation of atomic entangled states in a bi-mode cavity via adiabatic passage
Li-Bo Chen, Peng Shi, Yong-Jian Gu +2
We propose schemes to prepare atomic entangled states in a bi-mode cavity via stimulated Raman adiabatic passage (STIRAP) and fractional stimulated Raman adiabatic passage (f-STIRA…
