Escaping Local Minima with Quantum Coherent Cooling
Jia-Jin Feng, Biao Wu
Quantum cooling has demonstrated its potential in quantum computing, which can reduce the number of control channels needed for external signals. Recent progress also supports the…
Transport theory for topological Josephson junctions with a Majorana qubit
Zhi Wang, Jia-Jin Feng, Zhao Huang +1
We construct a semiclassical theory for the transport of topological junctions starting from a microscopic Hamiltonian that comprehensively includes the interplay among the Majoran…
Quantum Computing by Cooling
Jiajin Feng, Biao Wu, Frank Wilczek
Interesting problems in quantum computation take the form of finding low-energy states of (pseudo)spin systems with engineered Hamiltonians that encode the problem data. Motivated…
Josephson radiation patterns in underdamped topological Josephson junctions
Yuejian Zhang, Xiping Yang, Jia-Jin Feng +2
Josephson radiation is a useful signature for detecting Majorana zero modes in topological superconductors. We study the Josephson radiation of the underdamped topological Josephso…
Microscope for Quantum Dynamics with Planck Cell Resolution
Zhenduo Wang, Jiajin Feng, Biao Wu
We introduce the out-of-time-correlation(OTOC) with the Planck cell resolution. The dependence of this OTOC on the initial state makes it function like a microscope, allowing us to…
Josephson radiation from nonlinear dynamics of Majorana zero modes
Jia-Jin Feng, Zhao Huang, Zhi Wang +1
Josephson radiation is a powerful method to probe Majorana zero modes in topological superconductors. Recently, Josephson radiation with half the Josephson frequency has been exper…
Hysteresis from nonlinear dynamics of Majorana modes in topological Josephson junctions
Jia-Jin Feng, Zhao Huang, Zhi Wang +1
We reveal that topological Josephson junctions provide a natural platform for the interplay between the Josephson effect and the Landau-Zener effect through a two-level system form…
