Temporal information processing on a 4,500-qubit quantum annealer
Antonio Sannia, Roberto Menta, Pratik Sathe +7
Quantum machine learning could uncover statistical structure beyond the reach of classical models, but this requires quantum models large and expressive enough to be useful and che…
All steerable quantum correlations can provide thermodynamic advantages in cooling
Tanmoy Biswas, Chandan Datta, Luis Pedro Garcia-Pintos
The removal of heat generated during computation poses a major challenge for both classical and quantum computation and information processing. In particular, removal of this heat…
Lower Bounds on Quantum Annealing Times
Luis Pedro García-Pintos, Lucas T. Brady, Jacob Bringewatt +1
The adiabatic theorem provides sufficient conditions for the time needed to prepare a target ground state. While it is possible to prepare a target state much faster with more gene…
Bounding the Minimum Time of a Quantum Measurement
Nathan Shettell, Federico Centrone, Luis Pedro García-Pintos
Measurements take a singular role in quantum theory. While they are often idealized as an instantaneous process, this is in conflict with all other physical processes in nature. In…
Limits on the Evolutionary Rates of Biological Traits
Luis Pedro García-Pintos
This paper focuses on the maximum speed at which biological evolution can occur. I derive inequalities that limit the rate of evolutionary processes driven by natural selection, mu…
Monitoring-induced Entanglement Entropy and Sampling Complexity
Mathias Van Regemortel, Oles Shtanko, Luis Pedro Garcia-Pintos +4
The dynamics of open quantum systems is generally described by a master equation, which describes the loss of information into the environment. By using a simple model of uncoupled…
Unifying Quantum and Classical Speed Limits on Observables
Luis Pedro García-Pintos, Schuyler Nicholson, Jason R. Green +2
The presence of noise or the interaction with an environment can radically change the dynamics of observables of an otherwise isolated quantum system. We derive a bound on the spee…
Energy storage and coherence in closed and open quantum batteries
Francesco Caravelli, Bin Yan, Luis Pedro Garcia-Pintos +1
We study the role of coherence in closed and open quantum batteries. We obtain upper bounds to the work performed or energy exchanged by both closed and open quantum batteries in t…
Time-information uncertainty relations in thermodynamics
Schuyler B. Nicholson, Luis Pedro Garcia-Pintos, Adolfo del Campo +1
Physical systems that power motion and create structure in a fixed amount of time dissipate energy and produce entropy. Whether living or synthetic, systems performing these dynami…
Fluctuations in extractable work bound the charging power of quantum batteries
Luis Pedro García-Pintos, Alioscia Hamma, Adolfo del Campo
We study the connection between the charging power of quantum batteries and the fluctuations of the extractable work. We prove that in order to have a non-zero rate of change of th…
Random Quantum Batteries
Francesco Caravelli, Ghislaine Coulter-De Wit, Luis Pedro Garcia-Pintos +1
Quantum nano-devices are fundamental systems in quantum thermodynamics that have been the subject of profound interest in recent years. Among these, quantum batteries play a very i…
Limits to Perception by Quantum Monitoring with Finite Efficiency
Luis Pedro García-Pintos, Adolfo del Campo
We formulate limits to perception under continuous quantum measurements by comparing the quantum states assigned by agents that have partial access to measurement outcomes. To this…
Time evolution of correlation functions in quantum many-body systems
Álvaro M. Alhambra, Jonathon Riddell, Luis Pedro García-Pintos
We give rigorous analytical results on the temporal behavior of two-point correlation functions --also known as dynamical response functions or Green's functions-- in closed many-b…
Extreme Decoherence and Quantum Chaos
Zhenyu Xu, Luis Pedro García-Pintos, Aurélia Chenu +1
We study the ultimate limits to the decoherence rate associated with dephasing processes. Fluctuating chaotic quantum systems are shown to exhibit extreme decoherence, with a rate…
Spontaneous symmetry breaking induced by quantum monitoring
Luis Pedro García-Pintos, Diego Tielas, Adolfo del Campo
Spontaneous symmetry breaking (SSB) is responsible for structure formation in scenarios ranging from condensed matter to cosmology. SSB is broadly understood in terms of perturbati…
Linear feedback stabilization of a dispersively monitored qubit
Taylor Lee Patti, Areeya Chantasri, Luis Pedro García-Pintos +2
The state of a continuously monitored qubit evolves stochastically, exhibiting competition between coherent Hamiltonian dynamics and diffusive partial collapse dynamics that follow…
Probing quantumness with joint continuous measurements of non-commuting qubit observables
Luis Pedro García-Pintos, Justin Dressel
We analyze the continuous measurement of two non-commuting observables for a qubit, and investigate whether the simultaneously observed noisy signals are consistent with the evolut…
Rapid estimation of drifting parameters in continuously measured quantum systems
Luis Cortez, Areeya Chantasri, Luis Pedro García-Pintos +2
We investigate the determination of a Hamiltonian parameter in a quantum system undergoing continuous measurement. We demonstrate a computationally rapid yet statistically optimal…
Equilibration time scales of physically relevant observables
Luis Pedro García-Pintos, Noah Linden, Artur S. L. Malabarba +2
We address the problem of understanding from first principles the conditions under which a quantum system equilibrates rapidly with respect to a concrete observable. On the one han…
Non-thermal quantum channels as a thermodynamical resource
Miguel Navascués, Luis Pedro García-Pintos
Quantum thermodynamics can be understood as a resource theory, whereby thermal states are free and the only allowed operations are unitary transformations commuting with the total…
Quantum Systems Equilibrate Rapidly for Most Observables
Artur S. L. Malabarba, Luis Pedro García-Pintos, Noah Linden +2
Considering any Hamiltonian, any initial state, and measurements with a small number of possible outcomes compared to the dimension, we show that most measurements are already equi…
A realist interpretation of quantum mechanics based on undecidability due to gravity
Rodolfo Gambini, Luis Pedro Garcia-Pintos, Jorge Pullin
We summarize several recent developments suggesting that solving the problem of time in quantum gravity leads to a solution of the measurement problem in quantum mechanics. This ap…
Undecidability as solution to the problem of measurement: fundamental criterion for the production of events
Rodolfo Gambini, Luis Pedro Garcia-Pintos, Jorge Pullin
In recent papers we put forth a new interpretation of quantum mechanics, colloquially known as ``the Montevideo interpretation''. This interpretation is based on taking into accoun…
An axiomatic formulation of the Montevideo interpretation of quantum mechanics
Rodolfo Gambini, Luis Pedro Garcia-Pintos, Jorge Pullin
We make a first attempt to axiomatically formulate the Montevideo interpretation of quantum mechanics. In this interpretation environmental decoherence is supplemented with loss of…
