Rationalizing Unphysical Radiation in the Unruh Effect by Extending Black Hole Spacetime
Yi-Bo Liang, Hong-Rong Li
We demonstrate that Schwarzschild spacetime has a conformal extension and that, beyond null infinity, there is a black hole with a timelike singularity. In conformal extended space…
Multi-output microwave single-photon source using superconducting circuits with longitudinal and transverse couplings
Xin Wang, Adam Miranowicz, Hong-Rong Li +1
Single-photon devices at microwave frequencies are important for applications in quantum information processing and communication in the microwave regime. In this work, we describe…
Preparing ground states and squeezed states of nanomechanical cantilevers by fast dissipation
Xin Wang, Hong-rong Li, Peng-bo Li +3
We propose a protocol that enables strong coupling between a flux qubit and the quantized motion of a magnetized nanomechanical cantilever. The flux qubit is driven by microwave fi…
Vibration-assisted coherent excitation energy transfer in a detuning system
Xin Wang, Hao Chen, Hong-rong Li
The roles of the vibration motions played in the excitation energy transfer process are studied. It is found that a strong coherent transfer in the hybrid system emerges when the d…
Implementation of one-dimensional quantum walks on spin-orbital angular momentum space of photons
Pei Zhang, Bi-Heng Liu, Rui-Feng Liu +3
Photons can carry spin angular momentum (SAM) and orbital angular momentum (OAM), which can be used to realize a qubit system and a high-dimension system respectively. This spin-or…
