Weak and strong measurement of a qubit using a switching-based detector
S. Ashhab, J. Q. You, Franco Nori
We analyze the operation of a switching-based detector that probes a qubit's observable that does not commute with the qubit's Hamiltonian, leading to a nontrivial interplay betwee…
Coupling strength estimation for spin chains despite restricted access
Daniel Burgarth, Koji Maruyama, Franco Nori
Quantum control requires full knowledge of the system many-body Hamiltonian. In many cases this information is not directly available due to restricted access to the system. Here w…
Protecting entanglement in superconducting qubits
Jing Zhang, Yu-xi Liu, Chun-Wen Li +2
When a two-qubit system is initially maximally-entangled, two independent decoherence channels, one per qubit, would greatly reduce the entanglement of the two-qubit system when it…
Controlling Quasibound States in 1D Continuum Through Electromagnetic Induced Transparency Mechanism
Z. R. Gong, H. Ian, Lan Zhou +1
We study the coherent scattering process of a single photon confined in an one-dimensional (1D) coupled cavity-array, where a -type three-level atom is placed inside one of the…
Cavity optomechanical coupling assisted by an atomic gas
H. Ian, Z. R. Gong, Yu-xi Liu +2
We theoretically study a cavity filled with atoms, which provides the optical-mechanical interaction between the modified cavity photonic field and a movable mirror at one end. We…
Entanglement purification without controlled-NOT gates by using the natural dynamics of spin chains
Koji Maruyama, Franco Nori
We present a simple protocol to purify bipartite entanglement in spin-1/2 particles by utilizing only natural spin-spin interactions, i.e. those that can commonly be realized in re…
