Variational Coherent Quantum Annealing
N. Barraza, G. Alvarado Barrios, I. Montalban +2
We present a hybrid classical-quantum computing paradigm where the quantum part strictly runs within the coherence time of a quantum annealer, a method we call variational coherent…
Deterministic single-photon source in the ultrastrong coupling regime
Jie Peng, Jianing Tang, Pinghua Tang +7
Deterministic single-photon sources are important and ubiquitous in quantum information protocols. However, to the best of our knowledge, none of them work in the ultrastrong light…
Tripartite entanglement in quantum memristors
S. Kumar, F. A. Cárdenas-López, N. N. Hegade +3
We study the entanglement and memristive properties of three coupled quantum memristors. We consider quantum memristors based on superconducting asymmetric SQUID architectures whic…
Swap Test with Quantum-Dot Charge Qubits
Y. -D. Li, N. Barraza, G. Alvarado Barrios +2
We propose the implementation of the Swap Test using a charge qubit in a double quantum dot. The Swap Test is a fundamental quantum subroutine in quantum machine learning and other…
Quantum Memristors with Quantum Computers
Y. -M. Guo, F. Albarrán-Arriagada, H. Alaeian +2
We propose the encoding of memristive quantum dynamics on a digital quantum computer. Using a set of auxiliary qubits, we simulate an effective non-Markovian environment inspired b…
One-photon Solutions to Multiqubit Multimode quantum Rabi model
Jie Peng, Juncong Zheng, Jing Yu +6
General solutions to the quantum Rabi model involve subspaces with unbounded number of photons. However, for the multiqubit multimode case, we find special solutions with at most o…
Light-matter quantum Otto engine in finite time
G. Alvarado Barrios, F. Albarrán-Arriagada, F. J. Peña +2
We study a quantum Otto engine at finite time, where the working substance is composed of a two-level system interacting with a harmonic oscillator, described by the quantum Rabi m…
Analog simulator of integro-differential equations with classical memristors
G. Alvarado Barrios, J. C. Retamal, E. Solano +1
An analog computer makes use of continuously changeable quantities of a system, such as its electrical, mechanical, or hydraulic properties, to solve a given problem. While these d…
Role of quantum correlations in light-matter quantum heat engines
G. Alvarado Barrios, F. Albarrán-Arriagada, F. A. Cárdenas-López +2
We study a quantum Otto engine embedding a working substance composed by a two-level system interacting with a harmonic mode. The physical properties of the substance are described…
Incoherent-mediator for quantum state transfer in the ultrastrong coupling regime
F. A. Cárdenas-López, F. Albarrán-Arriagada, G. Alvarado Barrios +2
We study quantum state transfer between two qubits coupled to a common quantum bus that is constituted by an ultrastrong coupled light-matter system. By tuning both qubit frequenci…
Generation of higher dimensional entangled states in quantum Rabi systems
F. Albarrán-Arriagada, G. Alvarado Barrios, F. A. Cardenas-López +2
We present protocols for the generation of high-dimensional entangled states of anharmonic oscillators by means of coherent manipulation of light-matter systems in the ultrastrong…
