Single-photon pulse induced giant response in N100 qubit system
Li-Ping Yang, Zubin Jacob
The temporal dynamics of large quantum systems perturbed weakly by a single excitation can give rise to unique phenomena at the quantum phase boundaries. Here, we develop a time-de…
Dirac Wire
Farhad Khosravi, Todd Van Mechelen, Zubin Jacob
The interplay of photon spin and orbital angular momentum (OAM) in the optical fiber (1D waveguide) has recently risen to the forefront of quantum nanophotonics. Here, we introduce…
Engineering First-Order Quantum Phase Transitions for Weak Signal Detection
Li-Ping Yang, Zubin Jacob
The quantum critical detector (QCD), recently introduced for weak-signal amplification [Opt. Express 27, 10482 (2019)], functions by exploiting high sensitivity near the phase tran…
Quantum maximum power transfer theorem
Cristian L. Cortes, Zubin Jacob
We discover the quantum analog of the well-known classical maximum power transfer theorem. Our theoretical framework considers the continuous steady-state problem of coherent energ…
Single-Photon Pulse Induced Transient Entanglement Force
Li-Ping Yang, Chinmay Khandekar, Tongcang Li +1
We show that a single photon pulse (SPP) incident on two interacting two-level atoms induces a transient entanglement force between them. After absorption of a multi-mode Fock stat…
