Emerging Non-Hermitian Topology in a Chiral Driven-Dissipative Bose-Hubbard Model
Laszlo Rassaert, Tomás Ramos, Tommaso Roscilde +1
We introduce a driven-dissipative Bose-Hubbard chain describing coupled lossy photonic modes, in which time-reversal symmetry is broken by a coherent drive with a uniform phase gra…
Improving quantum metrology protocols with programmable photonic circuits
A. Muñoz de las Heras, D. Porras, A. González-Tudela
Photonic quantum metrology enables the measurement of physical parameters with precision surpassing classical limits by using quantum states of light. However, generating states pr…
Topological, multi-mode amplification induced by non-reciprocal, long-range dissipative couplings
Carlos Vega, Alberto Muñoz de las Heras, Diego Porras +1
Non-reciprocal couplings or drivings are known to induce steady-state, directional, amplification in driven-dissipative bosonic lattices. This amplification phenomenon has been rec…
Connection between single-layer Quantum Approximate Optimization Algorithm interferometry and thermal distributions sampling
Pablo Díez-Valle, Diego Porras, Juan José García-Ripoll
The Quantum Approximate Optimization Algorithm (QAOA) is an algorithm originally proposed to find approximate solutions to Combinatorial Optimization problems on quantum computers.…
Photonic quantum metrology with variational quantum optical non-linearities
A. Muñoz de las Heras, C. Tabares, J. T. Schneider +3
Photonic quantum metrology harnesses quantum states of light, such as NOON or Twin-Fock states, to measure unknown parameters beyond classical precision limits. Current protocols s…
Multiobjective variational quantum optimization for constrained problems: an application to Cash Management
Pablo Díez-Valle, Jorge Luis-Hita, Senaida Hernández-Santana +6
Combinatorial optimization problems are ubiquitous in industry. In addition to finding a solution with minimum cost, problems of high relevance involve a number of constraints that…
Variational waveguide QED simulators
Cristian Tabares, Alberto Muñoz de las Heras, Luca Tagliacozzo +2
Waveguide QED simulators are analogue quantum simulators made by quantum emitters interacting with one-dimensional photonic band-gap materials. One of their remarkable features is…
