Solid-state heteronuclear multiple-quantum spectroscopy under a magic-angle spinning frequency of 150 kHz
Eric Chung-Yueh Yuan, Po-Wen Chen, Shing-Jong Huang +3
We hereby demonstrate that 1H detected 15N-1H heteronuclear multiple-quantum spectroscopy can be carried out at a magic angle spinning frequency of 150 kHz. While the 15N-1H multip…
Time dynamics of quantum coherence and monogamy in a non-Markovian environment
Chandrashekar Radhakrishnan, Po-Wen Chen, Segar Jambulingam +2
The time evolution of the distribution and shareability of quantum coherence of a tripartite system in a non-Markovian environment is examined. The total coherence can be decompose…
Probing nonclassicality under spontaneous decay
Md. Manirul Ali, Po-Wen Chen
We investigate the nonclassicality of an open quantum system using Leggett-Garg inequality (LGI) which test the correlations of a single system measured at different times. Violati…
Quantum Zeno dynamics of qubits in a squeezed reservoir: effect of measurement selectivity
Md. Manirul Ali, Po-Wen Chen, Alec Maassen van den Brink +1
A complete suppression of the exponential decay in a qubit (interacting with a squeezed vacuum reservoir) can be achieved by frequent measurements of adequately chosen observables.…
Non-Markovian finite-temperature two-time correlation functions of system operators: beyond the quantum regression theorem
Hsi-Sheng Goan, Po-Wen Chen, Chung-Chin Jian
An extremely useful evolution equation that allows systematically calculating the two-time correlation functions (CF's) of system operators for non-Markovian open (dissipative) qua…
Non-Markovian dynamics of a nanomechanical resonator measured by a quantum point contact
Po-Wen Chen, Chung-Chin Jian, Hsi-Sheng Goan
We study the dynamics of a nanomechanical resonator (NMR) subject to a measurement by a low transparency quantum point contact (QPC) or tunnel junction in the non-Markovian domain.…
Decoherence-free subspace and disentanglement dynamics for two qubits in a common non-Markovian squeezed reservoir
Md. Manirul Ali, Po-Wen Chen, Hsi-Sheng Goan
We study the non-Markovian entanglement dynamics of two qubits in a common squeezed bath. We see remarkable difference between the non-Markovian entanglement dynamics with its Mark…
Non-Markovian finite-temperature two-time correlation functions of system operators of a pure-dephasing model
Hsi-Sheng Goan, Chung-Chin Jian, Po-Wen Chen
We evaluate the non-Markovian finite-temperature two-time correlation functions (CF's) of system operators of a pure-dephasing spin-boson model in two different ways, one by the di…
Optimal control of the silicon-based donor electron spin quantum computing
Dong-Bang Tsai, Po-Wen Chen, Hsi-Sheng Goan
We demonstrate how gradient ascent pulse engineering optimal control methods can be implemented on donor electron spin qubits in Si semiconductors with an architecture complementar…
