Mean-Field Solution of the Weak-Strong Cluster Problem for Quantum Annealing with Stoquastic and Non-Stoquastic Catalysts
Kabuki Takada, Yu Yamashiro, Hidetoshi Nishimori
We study the weak-strong cluster problem for quantum annealing in its mean-field version as proposed by Albash [Phys. Rev. A 99 (2019) 042334] who showed by numerical diagonalizati…
Reverse quantum annealing of the -spin model with relaxation
Gianluca Passarelli, Ka-Wa Yip, Daniel A. Lidar +2
In reverse quantum annealing, the initial state is an eigenstate of the final problem Hamiltonian and the transverse field is cycled rather than strictly decreased as in standard (…
Speeding-up a quantum refrigerator via counter-diabatic driving
Ken Funo, Neill Lambert, Bayan Karimi +3
We study the application of a counter-diabatic driving (CD) technique to enhance the thermodynamic efficiency and power of a quantum Otto refrigerator based on a superconducting qu…
Time-domain grating with a periodically driven qutrit
Yingying Han, Xiao-Qing Luo, Tie-Fu Li +5
Physical systems in the time domain may exhibit analogous phenomena in real space, such as time crystals, time-domain Fresnel lenses, and modulational interference in a qubit. Here…
Scully-Lamb quantum laser model for parity-time-symmetric whispering-gallery microcavities: Gain saturation effects and non-reciprocity
Ievgen I. Arkhipov, Adam Miranowicz, Omar Di Stefano +4
We use a non-Lindbladian master equation of the Scully-Lamb laser model for the analysis of light propagation in a parity-time symmetric photonic system composed of coupled active…
